TobraDex (dexamethasone 0.1 % / tobramycin 0.3 % ) Ophthalmic Suspension

WARNINGS

: FOR TOPICAL OPHTHALMIC USE.

NOT FOR INJECTION INTO THE EYE.

Sensitivity to topically applied aminoglycosides may occur in some patients.

Severity of hypersensitivity reactions may vary from local effects to generalized reactions, such as erythema, itching, urticaria, skin rash, anaphylaxis, anaphylactoid reactions, or bullous reactions.

If a sensitivity reaction does occur, discontinue use.

Prolonged use of steroids may result in glaucoma, with damage to the optic nerve, defects in visual acuity and fields of vision, and posterior subcapsular cataract formation.

Intraocular pressure (IOP) should be routinely monitored even though it may be difficult in pediatric patients and uncooperative patients.

Prolonged use may suppress the host response and thus increase the hazard of secondary ocular infections.

In acute purulent conditions and parasitic infections of the eye, steroids may mask infection or enhance existing infection.

In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids.

GERIATRIC USE

Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly and younger patients.

INDICATIONS AND USAGE

: TOBRADEX ® (tobramycin and dexamethasone ophthalmic suspension) is indicated for steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where superficial bacterial ocular infection or a risk of bacterial ocular infection exists.

Ocular steroids are indicated in inflammatory conditions of the palpebral and bulbar conjunctiva, cornea and anterior segment of the globe where the inherent risk of steroid use in certain infective conjunctivitides is accepted to obtain a diminution in edema and inflammation.

They are also indicated in chronic anterior uveitis and corneal injury from chemical, radiation or thermal burns, or penetration of foreign bodies.

The use of a combination drug with an anti-infective component is indicated where the risk of superficial ocular infection is high or where there is an expectation that potentially dangerous numbers of bacteria will be present in the eye.

The particular anti-infective drug in this product is active against the following common bacterial eye pathogens: Staphylococci , including S.

aureus and S.

epidermidis (coagulase-positive and coagulase-negative), including penicillin-resistant strains.

Streptococci , including some of the Group A-beta-hemolytic species, some nonhemolytic species, and some Streptococcus pneumoniae.

Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Proteus mirabilis, Morganella morganii, most Proteus vulgaris strains, Haemophilus influenzae and H.

aegyptius, Moraxella lacunata, Acinetobacter calcoaceticus and some Neisseria species.

PEDIATRIC USE

Pediatric Use: Safety and effectiveness in pediatric patients below the age of 2 years have not been established.

PREGNANCY

Pregnancy: Corticosteroids have been found to be teratogenic in animal studies.

Ocular administration of 0.1% dexamethasone resulted in 15.6% and 32.3% incidence of fetal anomalies in two groups of pregnant rabbits.

Fetal growth retardation and increased mortality rates have been observed in rats with chronic dexamethasone therapy.

Reproduction studies have been performed in rats and rabbits with tobramycin at doses up to 100 mg/kg/day parenterally and have revealed no evidence of impaired fertility or harm to the fetus.

There are no adequate and well-controlled studies in pregnant women.

However, prolonged or repeated corticoid use during pregnancy has been associated with an increased risk of intra-uterine growth retardation.

TOBRADEX (tobramycin and dexamethasone ophthalmic suspension) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Infants born of mothers who have received substantial doses of corticosteroids during pregnancy should be observed carefully for signs of hypoadrenalism.

NUSRING MOTHERS

Nursing Mothers: Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects.

It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk.

Because many drugs are excreted in human milk, caution should be exercised when TOBRADEX (tobramycin and dexamethasone ophthalmic suspension) is administered to a nursing woman.

INFORMATION FOR PATIENTS

Information for Patients: Do not touch dropper tip to any surface, as this may contaminate the contents.

Contact lenses should not be worn during the use of this product.

DOSAGE AND ADMINISTRATION

: One or two drops instilled into the conjunctival sac(s) every four to six hours.

During the initial 24 to 48 hours, the dosage may be increased to one or two drops every two (2) hours.

Frequency should be decreased gradually as warranted by improvement in clinical signs.

Care should be taken not to discontinue therapy prematurely.

Not more than 20 mL should be prescribed initially and the prescription should not be refilled without further evaluation as outlined in PRECAUTIONS above.

Atrovent HFA 17 MCG per ACTUAT Metered Dose Inhaler, 200 ACTUAT

Generic Name: IPRATROPIUM BROMIDE
Brand Name: Atrovent HFA
  • Substance Name(s):
  • IPRATROPIUM BROMIDE

DRUG INTERACTIONS

7 ATROVENT HFA has been used concomitantly with other drugs, including sympathomimetic bronchodilators, methylxanthines, oral and inhaled steroids commonly used in the treatment of COPD.

With the exception of albuterol, there are no formal studies fully evaluating the interaction effects of ATROVENT HFA and these drugs with respect to safety and effectiveness.

Anticholinergics: May interact additively with concomitantly used anticholinergic medications.

Avoid administration of ATROVENT HFA with other anticholinergic-containing drugs ( 7.1 ) 7.1 Anticholinergic Agents There is potential for an additive interaction with concomitantly used anticholinergic medications.

Therefore, avoid coadministration of ATROVENT HFA with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects [ see Warnings and Precautions (5.4 , 5.5) ].

OVERDOSAGE

10 Acute overdose by inhalation is unlikely since ipratropium bromide is not well absorbed systemically after inhalation or oral administration.

DESCRIPTION

11 The active ingredient in ATROVENT HFA is ipratropium bromide (monohydrate).

It is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo[3.2.1]octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8-methyl-8-(1-methylethyl)-,bromide monohydrate, (3-endo, 8-syn)-: a synthetic quaternary ammonium compound, chemically related to atropine.

The structural formula for ipratropium bromide is: C 20 H 30 BrNO 3 ∙H 2 O ipratropium bromide Mol.

Wt.

430.4 Ipratropium bromide is a white to off-white crystalline substance, freely soluble in water and methanol, sparingly soluble in ethanol, and insoluble in lipophilic solvents such as ether, chloroform, and fluorocarbons.

ATROVENT HFA is a pressurized metered-dose aerosol unit for oral inhalation that contains a solution of ipratropium bromide.

The 200 inhalation unit has a net weight of 12.9 grams.

After priming, each actuation of the inhaler delivers 21 mcg of ipratropium bromide (monohydrate) from the valve in 56 mg of solution and delivers 17 mcg of ipratropium bromide (monohydrate) from the mouthpiece.

The actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between the actuation of the device and inspiration through the delivery system.

The excipients are anhydrous citric acid, dehydrated alcohol, HFA-134a (1,1,1,2-tetrafluoroethane) as propellant, and sterile water for irrigation.

This product does not contain chlorofluorocarbons (CFCs) as propellants.

ATROVENT HFA should be primed before using for the first time by releasing 2 test sprays into the air away from the face.

In cases where the inhaler has not been used for more than 3 days, prime the inhaler again by releasing 2 test sprays into the air away from the face.

Chemical Structure

CLINICAL STUDIES

14 Conclusions regarding the efficacy of ATROVENT HFA were derived from two randomized, double-blind, controlled clinical studies.

These studies enrolled males and females ages 40 years and older, with a history of COPD, a smoking history of >10 pack-years, an FEV 1 <65% and an FEV 1 /FVC <70%.

One of the studies was a 12-week randomized, double-blind active, and placebo-controlled study in which 505 of the 507 randomized COPD patients were evaluated for the safety and efficacy of 42 mcg (n=124) and 84 mcg (n=126) ATROVENT HFA in comparison to 42 mcg (n=127) ATROVENT CFC and their respective placebos (HFA n=62, CFC n=66).

Data for both placebo HFA and placebo CFC were combined in the evaluation.

Serial FEV 1 (shown in Figure 1, below, as means adjusted for center and baseline effects on test day 1 and test day 85 (primary endpoint)) demonstrated that 1 dose (2 inhalations/21 mcg each) of ATROVENT HFA produced significantly greater improvement in pulmonary function than placebo.

During the six hours immediately post-dose on day 1, the average hourly improvement in adjusted mean FEV 1 was 0.148 liters for ATROVENT HFA (42 mcg) and 0.013 liters for placebo.

The mean peak improvement in FEV 1 , relative to baseline, was 0.295 liters, compared to 0.138 liters for placebo.

During the six hours immediately post-dose on day 85, the average hourly improvement in adjusted mean FEV 1 was 0.141 liters for ATROVENT HFA (42 mcg) and 0.014 liters for placebo.

The mean peak improvement in FEV 1 , relative to baseline, was 0.295 liters, compared to 0.140 liters for placebo.

ATROVENT HFA (42 mcg) was shown to be clinically comparable to ATROVENT CFC (42 mcg).

Figure 1 Day 1 and Day 85 (Primary Endpoint) Results In this study, both ATROVENT HFA and ATROVENT CFC formulations were equally effective in patients over 65 years of age and under 65 years of age.

The median time to improvement in pulmonary function (FEV 1 increase of 15% or more) was within approximately 15 minutes, reached a peak in 1 to 2 hours, and persisted for 2 to 4 hours in the majority of the patients.

Improvements in Forced Vital Capacity (FVC) were also demonstrated.

The other study was a 12-week, randomized, double-blind, active-controlled clinical study in 174 adults with COPD, in which ATROVENT HFA 42 mcg (n=118) was compared to ATROVENT CFC 42 mcg (n=56).

Safety and efficacy of HFA and CFC formulations were shown to be comparable.

The bronchodilatory efficacy and comparability of ATROVENT HFA vs ATROVENT CFC were also studied in a one-year open-label safety and efficacy study in 456 COPD patients.

The safety and efficacy of HFA and CFC formulations were shown to be comparable.

HOW SUPPLIED

16 /STORAGE AND HANDLING ATROVENT HFA is supplied in a pressurized stainless steel canister as a metered-dose inhaler with a white mouthpiece that has a clear, colorless sleeve and a green protective cap (NDC 0597-0087-17).

The mouthpiece has an actuation indicator visible through a small window.

The indicator typically moves during every 5 to 7 actuations.

It displays the approximate number of actuations remaining in increments of 20, starting at “200” and decreasing until it reaches “0”.

The ATROVENT HFA canister is to be used only with the accompanying ATROVENT HFA mouthpiece.

This mouthpiece should not be used with other aerosol medications.

Similarly, the canister should not be used with other mouthpieces.

After priming, each actuation of ATROVENT HFA delivers 21 mcg of ipratropium bromide (monohydrate) from the valve and 17 mcg from the mouthpiece.

Each canister has a net weight of 12.9 grams and provides sufficient medication for 200 actuations.

The inhaler should be discarded after the labeled number of actuations has been used when the indicator displays “0”.

The amount of medication in each actuation cannot be assured after this point, even though the canister is not completely empty.

Storage Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature].

For optimal results, the canister should be at room temperature before use.

Contents Under Pressure: Do not puncture.

Do not use or store near heat or open flame.

Exposure to temperatures above 120°F may cause bursting.

Never throw the inhaler into a fire or incinerator.

Keep out of reach of children.

Avoid spraying in eyes .

GERIATRIC USE

8.5 Geriatric Use In the pivotal 12-week study, both ATROVENT HFA and ATROVENT CFC formulations were equally effective in patients over 65 years of age and under 65 years of age.

Of the total number of subjects in clinical studies of ATROVENT HFA, 57% were ≥65 years of age.

No overall differences in safety or effectiveness were observed between these subjects and younger subjects.

DOSAGE FORMS AND STRENGTHS

Each pressurized metered-dose aerosol unit for oral inhalation contains a 12.9 g solution of ipratropium bromide (monohydrate) that provides sufficient medication for 200 actuations.

After priming, each actuation of the inhaler delivers 21 mcg of ipratropium bromide (monohydrate) from the valve and delivers 17 mcg of ipratropium bromide (monohydrate) from the mouthpiece.

Inhalation Aerosol: Each actuation of ATROVENT HFA Inhalation Aerosol delivers 17 mcg of ipratropium bromide (monohydrate) from the mouthpiece ( 3 ) Supplied in a 12.9 g canister containing 200 actuations ( 3 )

MECHANISM OF ACTION

12.1 Mechanism of Action Ipratropium bromide is an anticholinergic (parasympatholytic) agent which, based on animal studies, appears to inhibit vagally-mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released at the neuromuscular junctions in the lung.

Anticholinergics prevent the increases in intracellular concentration of Ca++ which is caused by interaction of acetylcholine with the muscarinic receptors on bronchial smooth muscle.

INDICATIONS AND USAGE

1 ATROVENT HFA Inhalation Aerosol is indicated as a bronchodilator for maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.

ATROVENT HFA is an anticholinergic indicated for the maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema ( 1 )

PEDIATRIC USE

8.4 Pediatric Use Safety and effectiveness in the pediatric population have not been established.

PREGNANCY

8.1 Pregnancy Risk Summary Ipratropium is negligibly absorbed systemically following oral inhalation; therefore, maternal use is not expected to result in fetal exposure to the drug [ see Clinical Pharmacology (12.3) ].

There is limited experience with ipratropium bromide use in pregnant women.

Published literature, including cohort studies, case control studies and case series, over several decades have not identified a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.

Based on animal reproduction studies, no evidence of structural alterations was observed when ipratropium bromide was administered to pregnant mice, rats and rabbits during organogenesis at doses up to approximately 200, 40,000, and 10,000 times, respectively, the maximum recommended human daily inhalation dose (MRHDID) in adults (see Data ) .

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defect, loss or other adverse outcomes.

In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data Animal Data In animal reproduction studies, oral and inhalation administration of ipratropium bromide to pregnant mice, rats and rabbits during the period of organogenesis did not show evidence of fetal structural alterations.

The ipratropium bromide dose in oral studies in mice, rats, and rabbits was up to approximately 200, 40,000, and 10,000 times, respectively, the MRHDID in adults (on a mg/m 2 basis at maternal doses of 10, 1,000, and 125 mg/kg/day, respectively).

The ipratropium bromide dose in inhalation studies in rats and rabbits was up to approximately 60 and 140 times, respectively, the MRHDID in adults (on a mg/m 2 basis at maternal doses of 1.5 and 1.8 mg/kg/day, respectively).

Embryotoxicity was observed as increased resorption in rats at oral doses approximately 3,600 times the MRHDID in adults (on a mg/m 2 basis at maternal doses of 90 mg/kg/day and above).

This effect is not considered relevant to human use due to the large doses at which it was observed and the difference in route of administration.

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS Not indicated for the initial treatment of acute episodes of bronchospasm where rescue therapy is required for rapid response ( 5.1 ) Hypersensitivity reactions including anaphylaxis: Discontinue ATROVENT HFA at once and consider alternative treatments ( 5.2 ) Paradoxical bronchospasm: Discontinue ATROVENT HFA and consider other treatments if paradoxical bronchospasm occurs ( 5.3 ) Ocular effects: Use with caution in patients with narrow-angle glaucoma and instruct patients to consult a physician immediately if signs or symptoms of narrow-angle glaucoma develop ( 5.4 ) Urinary retention: Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patients to consult a physician immediately if signs or symptoms of urinary retention develop ( 5.5 ) 5.1 Use for Maintenance Treatment Only ATROVENT HFA is a bronchodilator for the maintenance treatment of bronchospasm associated with COPD and is not indicated for the initial treatment of acute episodes of bronchospasm where rescue therapy is required for rapid response.

5.2 Hypersensitivity Reactions, Including Anaphylaxis Hypersensitivity reactions including urticaria, angioedema, rash, bronchospasm, anaphylaxis, and oropharyngeal edema may occur after the administration of ATROVENT HFA.

In clinical trials and postmarketing experience with ipratropium-containing products, hypersensitivity reactions such as skin rash, pruritus, angioedema of tongue, lips and face, urticaria (including giant urticaria), laryngospasm and anaphylactic reactions have been reported [ see Adverse Reactions (6.1 , 6.2) ].

If such a reaction occurs, therapy with ATROVENT HFA should be stopped at once and alternative treatment should be considered [ see Contraindications (4) ] .

5.3 Paradoxical Bronchospasm ATROVENT HFA can produce paradoxical bronchospasm that can be life threatening.

If this occurs, treatment with ATROVENT HFA should be stopped and other treatments considered.

5.4 Ocular Effects ATROVENT HFA is an anticholinergic and its use may increase intraocular pressure.

This may result in precipitation or worsening of narrow-angle glaucoma.

Therefore, ATROVENT HFA should be used with caution in patients with narrow-angle glaucoma [ see Drug Interactions (7.1) ].

Patients should avoid spraying ATROVENT HFA into their eyes.

If a patient sprays ATROVENT HFA into their eyes, they may cause eye pain or discomfort, temporary blurring of vision, mydriasis, visual halos or colored images in association with red eyes from conjunctival and corneal congestion.

Advise patients to consult their physician immediately if any of these symptoms develop while using ATROVENT HFA Inhalation Aerosol.

5.5 Urinary Retention ATROVENT HFA is an anticholinergic and may cause urinary retention.

Therefore, caution is advised when administering ATROVENT HFA Inhalation Aerosol to patients with prostatic hyperplasia, or bladder-neck obstruction [ see Drug Interactions (7.1) ].

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Instructions for Use).

Appropriate and safe use of ATROVENT HFA includes providing the patient with the information listed below and an understanding of the way it should be administered.

Advise patients that ATROVENT HFA is a bronchodilator for the maintenance treatment of bronchospasm associated with COPD and is not indicated for the initial treatment of acute episodes of bronchospasm where rescue therapy is required for rapid response.

Hypersensitivity Reactions Inform patients that hypersensitivity reactions, including urticaria, angioedema, rash, bronchospasm, anaphylaxis, and oropharyngeal edema, may occur after the administration of ATROVENT HFA.

Advise patients to immediately discontinue ATROVENT HFA and consult a physician [ see Warnings and Precautions (5.2) ] .

Paradoxical Bronchospasm Inform patients that ATROVENT HFA can produce paradoxical bronchospasm that can be life-threatening.

If paradoxical bronchospasm occurs, patients should discontinue using ATROVENT HFA.

Ocular Effects Caution patients to avoid spraying the aerosol into their eyes and be advised that this may result in precipitation or worsening of narrow-angle glaucoma, mydriasis, increased intraocular pressure, acute eye pain or discomfort, temporary blurring of vision, visual halos or colored images in association with red eyes from conjunctival and corneal congestion.

Patients should also be advised that should any combination of these symptoms develop, they should consult their physician immediately.

Since dizziness, accommodation disorder, mydriasis, and blurred vision may occur with use of ATROVENT HFA, patients should be cautioned about engaging in activities requiring balance and visual acuity such as driving a car or operating appliances or machinery.

Urinary Retention Inform patients that ATROVENT HFA may cause urinary retention and should be advised to consult their physicians if they experience difficulty with urination.

Frequency of Use The action of ATROVENT HFA should last 2 to 4 hours.

Advise patients not to increase the dose or frequency of ATROVENT HFA without patients consulting their physician.

Advise patients to seek immediate medical attention if treatment with ATROVENT HFA becomes less effective for symptomatic relief, their symptoms become worse, and/or patients need to use the product more frequently than usual.

Concomitant Drug Use Advise patients on the use of ATROVENT HFA in relation to other inhaled drugs [ see Drug Interactions (7.1) ].

Use Only as Prescribed Remind patients that ATROVENT HFA should be used consistently as prescribed throughout the course of therapy.

Preparation for Use and Priming Instruct patients that priming ATROVENT HFA is essential to ensure appropriate content of the medication in each actuation.

Patients do not have to shake the ATROVENT HFA canister before use .

DOSAGE AND ADMINISTRATION

2 The usual starting dosage of ATROVENT HFA is two inhalations four times a day.

Patients may take additional inhalations as required; however, the total number of inhalations should not exceed 12 in 24 hours.

ATROVENT HFA is a solution aerosol that does not require shaking.

However, as with any other metered-dose inhaler, some coordination is required between actuating the canister and inhaling the medication.

Patients should “prime” or actuate ATROVENT HFA before using for the first time by releasing 2 test sprays into the air away from the face.

In cases where the inhaler has not been used for more than 3 days, prime the inhaler again by releasing 2 test sprays into the air away from the face.

Patients should avoid spraying ATROVENT HFA into their eyes.

Each inhaler provides sufficient medication for 200 actuations.

The inhaler should be discarded after the labeled number of actuations has been used.

The amount of medication in each actuation cannot be assured after this point, even though the canister is not completely empty.

Patients should be instructed on the proper use of their inhaler [ see Patient Counseling Information (17) ].

For oral inhalation only Two inhalations four times a day, not to exceed 12 inhalations in 24 hours ( 2 )

Albuterol 1 MG/ML Inhalant Solution

WARNINGS

Paradoxical Bronchospasm: Albuterol sulfate inhalation solution can produce paradoxical bronchospasm, which may be life threatening.

If paradoxical bronchospasm occurs, albuterol sulfate inhalation solution should be discontinued immediately and alternative therapy instituted.

It should be recognized that paradoxical bronchospasm, when associated with inhaled formulations, frequently occurs with the first use of a new canister or vial.

Albuterol sulfate inhalation solution contains the preservative benzalkonium chloride.

Benzalkonium chloride has been associated with bronchospasm in a dose-dependent manner.

In patients who receive high doses (e.g., continuous nebulization) of albuterol sulfate inhalation solution and bronchospasm does not resolve, consider a trial of short-acting bronchodilator that does not contain the preservative benzalkonium chloride [see Dosage and Administration ].

Fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs and with the home use of nebulizers.

It is therefore essential that the physician instruct the patient in the need for further evaluation if his/her asthma becomes worse.

Cardiovascular Effects: Albuterol sulfate inhalation solution, like all other betaadrenergic agonists, can produce a clinically significant cardiovascular effect in some patients as measured by pulse rate, blood pressure, and/or symptoms.

Although such effects are uncommon after administration of albuterol sulfate inhalation solution at recommended doses, if they occur, the drug may need to be discontinued.

In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTC interval, and ST segment depression.

The clinical significance of these findings is unknown.

Therefore, albuterol sulfate inhalation solution, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.

Deterioration of Asthma: Asthma may deteriorate acutely over a period of hours or chronically over several days or longer.

If the patient needs more doses of albuterol sulfate inhalation solution than usual, this may be a marker of destabilization of asthma and requires reevaluation of the patient and treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids.

Immediate Hypersensitivity Reactions: Immediate hypersensitivity reactions may occur after administration of albuterol, as demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm, and oropharyngeal edema.

Use of Anti-inflammatory Agents: The use of beta-adrenergic agonist bronchodilators alone may not be adequate to control asthma in many patients.

Early consideration should be given to adding anti-inflammatory agents, e.g., corticosteroids.

Microbial Contamination: It is recommended that each multi-dose bottle of albuterol be used for only one patient.

Nosocomial outbreaks of pneumonia have occurred in hospitals when one multi-dose bottle of albuterol was used to treat more than one patient.

To avoid microbial contamination, proper aseptic technique should be used each time the bottle is opened.

Precautions should be taken to prevent contact of the dropper tip of the bottle with any surface, including the nebulizer reservoir and associated ventilatory equipment.

In addition, if the solution changes color or becomes cloudy, it should not be used.

DRUG INTERACTIONS

Drug Interactions Other short-acting sympathomimetic aerosol bronchodilators or epinephrine should not be used concomitantly with albuterol.

If additional adrenergic drugs are to be administered by any route, they should be used with caution to avoid deleterious cardiovascular effects.

Monoamine Oxidase Inhibitors or Tricyclic Antidepressants: Albuterol should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of albuterol on the vascular system may be potentiated.

Beta-Blockers: Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as albuterol sulfate inhalation solution, but may produce severe bronchospasm in asthmatic patients.

Therefore, patients with asthma should not normally be treated with beta-blockers.

However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents in patients with asthma.

In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.

Diuretics: The ECG changes and/or hypokalemia that may result from the administration of nonpotassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded.

Although the clinical significance of these effects is not known, caution is advised in the coadministration of beta-agonists with nonpotassium-sparing diuretics.

Digoxin: Mean decreases of 16% to 22% in serum digoxin levels were demonstrated after single-dose intravenous and oral administration of albuterol, respectively, to normal volunteers who had received digoxin for 10 days.

The clinical significance of these findings for patients with obstructive airway disease who are receiving albuterol and digoxin on a chronic basis is unclear.

Nevertheless, it would be prudent to carefully evaluate the serum digoxin levels in patients who are currently receiving digoxin and albuterol.

OVERDOSAGE

The expected symptoms with overdosage are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the symptoms listed under ADVERSE REACTIONS , e.g., seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats/min, arrhythmias, nervousness, headache, tremor, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, and sleeplessness.

Hypokalemia may also occur.

In isolated cases in children 2 to 12 years of age, tachycardia with rates >200 beats/min has been observed.

As with all sympathomimetic medications, cardiac arrest and even death may be associated with abuse of albuterol sulfate inhalation solution.

Treatment consists of discontinuation of albuterol sulfate inhalation solution together with appropriate symptomatic therapy.

The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm.

There is insufficient evidence to determine if dialysis is beneficial for overdosage of albuterol sulfate inhalation solution.

The oral median lethal dose of albuterol sulfate in mice is greater than 2000 mg/kg (approximately 810 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis or approximately 300 times the maximum recommended daily dose for children on a mg/m 2 basis).

In mature rats, the subcutaneous (sc) median lethal dose of albuterol sulfate is approximately 450 mg/kg (approximately 365 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis or approximately 135 times the maximum recommended daily inhalation dose for children on a mg/m 2 basis).

In small young rats, the sc median lethal dose is approximately 2000 mg/kg (approximately 1600 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis or approximately 600 times the maximum recommended daily inhalation dose for children on a mg/m 2 basis).

The inhalational median lethal dose has not been determined in animals.

INDICATIONS AND USAGE

Albuterol sulfate inhalation solution is indicated for the relief of bronchospasm in patients 2 years of age and older with reversible obstructive airway disease and acute attacks of bronchospasm.

PEDIATRIC USE

Pediatric Use The safety and effectiveness of albuterol sulfate inhalation solution have been established in children 2 years of age and older.

Use of albuterol sulfate inhalation solution in these age-groups is supported by evidence from adequate and well-controlled studies of albuterol sulfate inhalation solution in adults; the likelihood that the disease course, pathophysiology, and the drug’s effect in pediatric and adult patients are substantially similar; and published reports of trials in pediatric patients 3 years of age or older.

The recommended dose for the pediatric population is based upon three published dose comparison studies of efficacy and safety in children 5 to17 years, and on the safety profile in both adults and pediatric patients at doses equal to or higher than the recommended doses.

The safety and effectiveness of albuterol sulfate inhalation solution in children below 2 years of age have not been established.

PREGNANCY

Pregnancy Pregnancy Category C: Albuterol has been shown to be teratogenic in mice.

A study in CD-1 mice at subcutaneous (sc) doses of 0.025, 0.25, and 2.5 mg/kg (approximately 1/100, 1/10, and 1.0 times, respectively, the maximum recommended daily inhalation dose for adults on a mg/m 2 basis) showed cleft palate formation in 5 of 111 (4.5%) fetuses at 0.25 mg/kg and in 10 of 108 (9.3%) fetuses at 2.5 mg/kg.

The drug did not induce cleft palate formation at the lowest dose, 0.025 mg/kg.

Cleft palate also occurred in 22 of 72 (30.5%) fetuses from females treated with 2.5 mg/kg of isoproterenol (positive control) subcutaneously (approximately 1.0 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis).

A reproduction study in Stride Dutch rabbits revealed cranioschisis in 7 of 19 (37%) fetuses when albuterol was administered orally at a 50-mg/kg dose (approximately 80 times the maximum recommended daily inhalation dose for adults on a mg/m 2 basis).

There are no adequate and well-controlled studies in pregnant women.

Albuterol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

During worldwide marketing experience, various congenital anomalies, including cleft palate and limb defects, have been rarely reported in the offspring of patients being treated with albuterol.

Some of the mothers were taking multiple medications during their pregnancies.

No consistent pattern of defects can be discerned, and a relationship between albuterol use and congenital anomalies has not been established.

NUSRING MOTHERS

Nursing Mothers It is not known whether this drug is excreted in human milk.

Because of the potential for tumorigenicity shown for albuterol in some animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

INFORMATION FOR PATIENTS

Information for Patients The action of albuterol sulfate inhalation solution may last up to 6 hours or longer.

Albuterol sulfate inhalation solution should not be used more frequently than recommended.

Do not increase the dose or frequency of albuterol sulfate inhalation solution without consulting your physician.

If you find that treatment with albuterol sulfate inhalation solution becomes less effective for symptomatic relief, your symptoms become worse, and/or you need to use the product more frequently than usual, you should seek medical attention immediately.

While you are using albuterol sulfate inhalation solution, other inhaled drugs and asthma medications should be taken only as directed by your physician.

Common adverse effects include palpitations, chest pain, rapid heart rate, and tremor or nervousness.

If you are pregnant or nursing, contact your physician about use of albuterol sulfate inhalation solution.

Effective and safe use of albuterol sulfate inhalation solution includes an understanding of the way that it should be administered.

Drug compatibility (physical and chemical), efficacy, and safety of albuterol sulfate inhalation solution when mixed with other drugs in a nebulizer have not been established.

See illustrated “ Patient’s Instructions for Use .”

DOSAGE AND ADMINISTRATION

To avoid microbial contamination, proper aseptic techniques should be used each time the bottle is opened.

Precautions should be taken to prevent contact of the dropper tip of the bottle with any surface, including the nebulizer reservoir and associated ventilatory equipment.

In addition, if the solution changes color or becomes cloudy, it should not be used.

Children 2 to 12 Years of Age For children 2 to 12 years of age, initial dosing should be based upon body weight (0.1 to 0.15 mg/kg per dose), with subsequent dosing titrated to achieve the desired clinical response.

Dosing should not exceed 2.5 mg three to four times daily by nebulization.

The following table outlines approximate dosing according to body weight.

Approximate Weight (kg) Approximate Weight (lb) Dose (mg) Volume of Inhalation Solution 10-15 22-33 1.25 0.25 mL >15 >33 2.5 0.5 mL The appropriate volume of the 0.5% inhalation solution should be diluted in sterile normal saline solution to a total volume of 3 mL prior to administration via nebulization.

Adults and Children Over 12 Years of Age The usual dosage for adults and children 12 years of age and older is 2.5 mg of albuterol administered three to four times daily by nebulization.

More frequent administration or higher doses are not recommended.

To administer 2.5 mg of albuterol, dilute 0.5 mL of the 0.5% inhalation solution with 2.5 mL of sterile normal saline solution.

The flow rate is regulated to suit the particular nebulizer so that albuterol sulfate inhalation solution will be delivered over approximately 5 to 15 minutes.

The use of albuterol sulfate inhalation solution can be continued as medically indicated to control recurring bouts of bronchospasm.

During this time most patients gain optimal benefit from regular use of the inhalation solution.

If a previously effective dosage regimen fails to provide the usual relief, medical advice should be sought immediately as this is often a sign of seriously worsening asthma that would require reassessment of therapy.

Drug compatibility (physical and chemical), efficacy, and safety of albuterol sulfate inhalation solution when mixed with other drugs in a nebulizer have not been established.

In patients who receive high doses (e.g., continuous nebulization) of Albuterol Sulfate Inhalation Solution and bronchospasm does not resolve, consider a trial of short acting bronchodilator that does not contain the preservative benzalkonium chloride [see WARNINGS – Paradoxical Bronchospasm ].

silver sulfADIAZINE 1 % Topical Cream

Generic Name: SILVER SULFADIAZINE
Brand Name: Silver Sulfadiazine
  • Substance Name(s):

(See CONTRAINDICATIONS )

PREGNANCY

: TERATOGENIC EFFECTS: Pregnancy Category B.

A reproductive study has been performed in rabbits at doses up to three to ten times the concentration of silver sulfadiazine in silver sulfadiazine cream, USP 1% and has revealed no evidence of harm to the fetus due to silver sulfadiazine.

There are, however, no adequate and well-controlled studies in pregnant women.

Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly justified, especially in pregnant women approaching or at term.

(See CONTRAINDICATIONS )

NUSRING MOTHERS

Nursing Mothers.

It is not known whether silver sulfadiazine cream, USP 1% is excreted in human milk.

However, sulfonamides are known to be excreted in human milk and all sulfonamides derivatives are known to increase the possibility of kernicterus.

Because of the possibility for serious adverse reactions in nursing infants from sulfonamides, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

DOSAGE AND ADMINISTRATION

Prompt institution of appropriate regimens for care of the burned patient is of prime importance and includes the control of shock and pain.

The burn wounds are then cleansed and debrided; silver sulfadiazine cream, USP 1% is then applied under sterile conditions.

The burn areas should be covered with silver sulfadiazine cream, USP 1% at all times.

The cream should be applied once to twice daily to a thickness of approximately one sixteenth of an inch.

Whenever necessary, the cream should be reapplied to any areas from which it has been removed by patient activity.

Administration may be accomplished in minimal time because dressings are not required.

However, if individual patient requirements make dressings necessary, they may be used.

Reapply immediately after hydrotherapy.

Treatment with silver sulfadiazine cream, USP 1% should be continued until satisfactory healing has occurred or until the burn site is ready for grafting.

The drug should not be withdrawn from the therapeutic regimen while there remains the possibility of infection except if a significant adverse reaction occurs.

pregabalin 300 MG Oral Capsule

DRUG INTERACTIONS

7 Since LYRICA is predominantly excreted unchanged in the urine, undergoes negligible metabolism in humans (less than 2% of a dose recovered in urine as metabolites), and does not bind to plasma proteins, its pharmacokinetics are unlikely to be affected by other agents through metabolic interactions or protein binding displacement.

In vitro and in vivo studies showed that LYRICA is unlikely to be involved in significant pharmacokinetic drug interactions.

Specifically, there are no pharmacokinetic interactions between pregabalin and the following antiepileptic drugs: carbamazepine, valproic acid, lamotrigine, phenytoin, phenobarbital, and topiramate.

Important pharmacokinetic interactions would also not be expected to occur between LYRICA and commonly used antiepileptic drugs [see Clinical Pharmacology (12) ] .

Pharmacodynamics Multiple oral doses of LYRICA were co-administered with oxycodone, lorazepam, or ethanol.

Although no pharmacokinetic interactions were seen, additive effects on cognitive and gross motor functioning were seen when LYRICA was co-administered with these drugs.

No clinically important effects on respiration were seen.

OVERDOSAGE

10 Signs, Symptoms and Laboratory Findings of Acute Overdosage in Humans There is limited experience with overdose of LYRICA.

The highest reported accidental overdose of LYRICA during the clinical development program was 8000 mg, and there were no notable clinical consequences.

In the postmarketing experience, the most commonly reported adverse events observed when LYRICA was taken in overdose included affective disorder, somnolence, confusional state, depression, agitation, and restlessness.

Seizures were also reported.

Treatment or Management of Overdose There is no specific antidote for overdose with LYRICA.

If indicated, elimination of unabsorbed drug may be attempted by emesis or gastric lavage; observe usual precautions to maintain the airway.

General supportive care of the patient is indicated including monitoring of vital signs and observation of the clinical status of the patient.

Contact a Certified Poison Control Center for up-to-date information on the management of overdose with LYRICA.

Although hemodialysis has not been performed in the few known cases of overdose, it may be indicated by the patient’s clinical state or in patients with significant renal impairment.

Standard hemodialysis procedures result in significant clearance of pregabalin (approximately 50% in 4 hours).

CLINICAL STUDIES

14 14.1 Neuropathic Pain Associated with Diabetic Peripheral Neuropathy The efficacy of the maximum recommended dose of LYRICA for the management of neuropathic pain associated with diabetic peripheral neuropathy was established in three double-blind, placebo-controlled, multicenter studies with three times a day dosing, two of which studied the maximum recommended dose.

Patients were enrolled with either Type 1 or Type 2 diabetes mellitus and a diagnosis of painful distal symmetrical sensorimotor polyneuropathy for 1 to 5 years.

A total of 89% of patients completed Studies DPN 1 and DPN 2.

The patients had a minimum mean baseline pain score of greater than or equal to 4 on an 11-point numerical pain rating scale ranging from 0 (no pain) to 10 (worst possible pain).

The baseline mean pain scores across the two studies ranged from 6.1 to 6.7.

Patients were permitted up to 4 grams of acetaminophen per day as needed for pain, in addition to pregabalin.

Patients recorded their pain daily in a diary.

Study DPN 1: This 5-week study compared LYRICA 25, 100, or 200 mg three times a day with placebo.

Treatment with LYRICA 100 and 200 mg three times a day statistically significantly improved the endpoint mean pain score and increased the proportion of patients with at least a 50% reduction in pain score from baseline.

There was no evidence of a greater effect on pain scores of the 200 mg three times a day dose than the 100 mg three times a day dose, but there was evidence of dose dependent adverse reactions [see Adverse Reactions (6.1) ] .

For a range of levels of improvement in pain intensity from baseline to study endpoint, Figure 1 shows the fraction of patients achieving that level of improvement.

The figure is cumulative, so that patients whose change from baseline is, for example, 50%, are also included at every level of improvement below 50%.

Patients who did not complete the study were assigned 0% improvement.

Some patients experienced a decrease in pain as early as Week 1, which persisted throughout the study.

Figure 2: Patients Achieving Various Levels of Improvement in Pain Intensity– Study DPN 2 Figure 2 14.2 Postherpetic Neuralgia The efficacy of LYRICA for the management of postherpetic neuralgia was established in three double-blind, placebo-controlled, multicenter studies.

These studies enrolled patients with neuralgia persisting for at least 3 months following healing of herpes zoster rash and a minimum baseline score of greater than or equal to 4 on an 11-point numerical pain rating scale ranging from 0 (no pain) to 10 (worst possible pain).

Seventy-three percent of patients completed the studies.

The baseline mean pain scores across the 3 studies ranged from 6 to 7.

Patients were permitted up to 4 grams of acetaminophen per day as needed for pain, in addition to pregabalin.

Patients recorded their pain daily in a diary.

Study PHN 1: This 13-week study compared LYRICA 75, 150, and 300 mg twice daily with placebo.

Patients with creatinine clearance (CLcr) between 30 to 60 mL/min were randomized to 75 mg, 150 mg, or placebo twice daily.

Patients with creatinine clearance greater than 60 mL/min were randomized to 75 mg, 150 mg, 300 mg or placebo twice daily.

In patients with creatinine clearance greater than 60 mL/min treatment with all doses of LYRICA statistically significantly improved the endpoint mean pain score and increased the proportion of patients with at least a 50% reduction in pain score from baseline.

Despite differences in dosing based on renal function, patients with creatinine clearance between 30 to 60 mL/min tolerated LYRICA less well than patients with creatinine clearance greater than 60 mL/min as evidenced by higher rates of discontinuation due to adverse reactions.

For various levels of improvement in pain intensity from baseline to study endpoint, Figure 3 shows the fraction of patients achieving that level of improvement.

The figure is cumulative, so that patients whose change from baseline is, for example, 50%, are also included at every level of improvement below 50%.

Figure 5: Patients Achieving Various Levels of Improvement in Pain Intensity– Study PHN 3 Figure 5 14.3 Adjunctive Therapy for Adult Patients with Partial Onset Seizures The efficacy of LYRICA as adjunctive therapy in partial onset seizures was established in three 12-week, randomized, double-blind, placebo-controlled, multicenter studies in adult patients.

Patients were enrolled who had partial onset seizures with or without secondary generalization and were not adequately controlled with 1 to 3 concomitant antiepileptic drugs (AEDs).

Patients taking gabapentin were required to discontinue gabapentin treatment 1 week prior to entering baseline.

During an 8-week baseline period, patients had to experience at least 6 partial onset seizures with no seizure-free period exceeding 4 weeks.

The mean duration of epilepsy was 25 years in these 3 studies and the mean and median baseline seizure frequencies were 22.5 and 10 seizures per month, respectively.

Approximately half of the patients were taking 2 concurrent AEDs at baseline.

Among the LYRICA-treated patients, 80% completed the double-blind phase of the studies.

Table 8 shows median baseline seizure rates and median percent reduction in seizure frequency by dose.

In the first study (E1), each daily dose was divided into two equal doses (twice a day dosing).

In the second study (E2), each daily dose was divided into three equal doses (three times a day dosing).

In the third study (E3), the same total daily dose was divided into two equal doses for one group (twice a day dosing) and three equal doses for another group (three times a day dosing).

While the three times a day dosing group in Study E3 performed numerically better than the twice a day dosing group, this difference was small and not statistically significant.

A secondary outcome measure included the responder rate (proportion of patients with greater than or equal to 50% reduction from baseline in partial seizure frequency).

The following figure displays responder rate by dose for two of the studies.

Figure 6: Responder rate by add-on epilepsy study Figure 7: Seizure Reduction by Dose (All Partial Onset Seizures) for Studies E1, E2, and E3 Subset evaluations of the antiseizure efficacy of LYRICA showed no clinically important differences as a function of age, gender, or race.

Figure 6 Figure 7 14.4 Management of Fibromyalgia The efficacy of LYRICA for management of fibromyalgia was established in one 14-week, double-blind, placebo-controlled, multicenter study (F1) and one six-month, randomized withdrawal study (F2).

Studies F1 and F2 enrolled patients with a diagnosis of fibromyalgia using the American College of Rheumatology (ACR) criteria (history of widespread pain for 3 months, and pain present at 11 or more of the 18 specific tender point sites).

The studies showed a reduction in pain by visual analog scale.

In addition, improvement was demonstrated based on a patient global assessment (PGIC), and on the Fibromyalgia Impact Questionnaire (FIQ).

Study F1 : This 14-week study compared LYRICA total daily doses of 300 mg, 450 mg and 600 mg with placebo.

Patients were enrolled with a minimum mean baseline pain score of greater than or equal to 4 on an 11-point numeric pain rating scale and a score of greater than or equal to 40 mm on the 100 mm pain visual analog scale (VAS).

The baseline mean pain score in this trial was 6.7.

Responders to placebo in an initial one-week run-in phase were not randomized into subsequent phases of the study.

A total of 64% of patients randomized to LYRICA completed the study.

There was no evidence of a greater effect on pain scores of the 600 mg daily dose than the 450 mg daily dose, but there was evidence of dose-dependent adverse reactions [ see Adverse Reactions (6.1) ].

Some patients experienced a decrease in pain as early as Week 1, which persisted throughout the study.

The results are summarized in Figure 8 and Table 9.

For various levels of improvement in pain intensity from baseline to study endpoint, Figure 8 shows the fraction of patients achieving that level of improvement.

The figure is cumulative.

Patients who did not complete the study were assigned 0% improvement.

Some patients experienced a decrease in pain as early as Week 1, which persisted throughout the study.

Patients were titrated during a 6-week open-label dose optimization phase to a total daily dose of 300 mg, 450 mg, or 600 mg.

Patients were considered to be responders if they had both: 1) at least a 50% reduction in pain (VAS) and, 2) rated their overall improvement on the PGIC as “much improved” or “very much improved.” Those who responded to treatment were then randomized in the double-blind treatment phase to either the dose achieved in the open-label phase or to placebo.

Patients were treated for up to 6 months following randomization.

Efficacy was assessed by time to loss of therapeutic response, defined as 1) less than 30% reduction in pain (VAS) from open-label baseline during two consecutive visits of the double-blind phase, or 2) worsening of FM symptoms necessitating an alternative treatment.

Fifty-four percent of patients were able to titrate to an effective and tolerable dose of LYRICA during the 6-week open-label phase.

Of the patients entering the randomized treatment phase assigned to remain on LYRICA, 38% of patients completed 26 weeks of treatment versus 19% of placebo-treated patients.

When considering return of pain or withdrawal due to adverse events as loss of response (LTR), treatment with LYRICA resulted in a longer time to loss of therapeutic response than treatment with placebo.

Fifty-three percent of the pregabalin-treated subjects compared to 33% of placebo patients remained on study drug and maintained a therapeutic response to Week 26 of the study.

Treatment with LYRICA also resulted in a longer time to loss of response based on the FIQ Time to worsening of the FIQ was defined as the time to a 1-point increase from double-blind baseline in each of the subscales, and a 5-point increase from double-blind baseline evaluation for the FIQ total score.

, and longer time to loss of overall assessment of patient status, as measured by the PGIC Time to PGIC lack of improvement was defined as time to PGIC assessments indicating less improvement than “much improvement.” .

Figure 9: Time to Loss of Therapeutic Response, Fibromyalgia Study F2 (Kaplan-Meier Analysis) Figure 9 14.5 Management of Neuropathic Pain Associated with Spinal Cord Injury The efficacy of LYRICA for the management of neuropathic pain associated with spinal cord injury was established in two double-blind, placebo-controlled, multicenter studies.

Patients were enrolled with neuropathic pain associated with spinal cord injury that persisted continuously for at least three months or with relapses and remissions for at least six months.

A total of 63% of patients completed study 1 and 84% completed study 2.

The patients had a minimum mean baseline pain score of greater than or equal to 4 on an 11-point numerical pain rating scale ranging from 0 (no pain) to 10 (worst possible pain).

The baseline mean pain scores across the two studies ranged from 6.5 to 6.7.

Patients were allowed to take opioids, non-opioid analgesics, antiepileptic drugs, muscle relaxants, and antidepressant drugs if the dose was stable for 30 days prior to screening.

Patients were allowed to take acetaminophen and nonsteroidal anti-inflammatory drugs during the studies.

Study SCI 1 : This 12-week, randomized, double-blind, parallel-group, multicenter, flexible dose (150–600 mg/day) study compared pregabalin with placebo.

The 12-week study consisted of a 3-week dose adjustment phase and a 9-week dose maintenance phase.

Treatment with LYRICA 150–600 mg/day statistically significantly improved the endpoint weekly mean pain score, and increased the proportion of patients with at least a 30% and 50% reduction in pain score from baseline.

The fraction of patients achieving various levels of improvement in pain intensity from baseline to Week 12 is presented in Figure 10.

Some patients experienced a decrease in pain as early as week 1, which persisted throughout the study.

GERIATRIC USE

8.5 Geriatric Use In controlled clinical studies of LYRICA in neuropathic pain associated with diabetic peripheral neuropathy, 246 patients were 65 to 74 years of age, and 73 patients were 75 years of age or older.

In controlled clinical studies of LYRICA in neuropathic pain associated with postherpetic neuralgia, 282 patients were 65 to 74 years of age, and 379 patients were 75 years of age or older.

In controlled clinical studies of LYRICA in epilepsy, there were only 10 patients 65 to 74 years of age, and 2 patients who were 75 years of age or older.

No overall differences in safety and efficacy were observed between these patients and younger patients.

In controlled clinical studies of LYRICA in fibromyalgia, 106 patients were 65 years of age or older.

Although the adverse reaction profile was similar between the two age groups, the following neurological adverse reactions were more frequent in patients 65 years of age or older: dizziness, vision blurred, balance disorder, tremor, confusional state, coordination abnormal, and lethargy.

LYRICA is known to be substantially excreted by the kidney, and the risk of toxic reactions to LYRICA may be greater in patients with impaired renal function.

Because LYRICA is eliminated primarily by renal excretion, adjust the dose for elderly patients with renal impairment [see Dosage and Administration (2.6) ] .

MECHANISM OF ACTION

12.1 Mechanism of Action LYRICA (pregabalin) binds with high affinity to the alpha 2 -delta site (an auxiliary subunit of voltage-gated calcium channels) in central nervous system tissues.

Although the mechanism of action of pregabalin has not been fully elucidated, results with genetically modified mice and with compounds structurally related to pregabalin (such as gabapentin) suggest that binding to the alpha 2 -delta subunit may be involved in pregabalin’s anti-nociceptive and antiseizure effects in animals.

In animal models of nerve damage, pregabalin has been shown to reduce calcium-dependent release of pro-nociceptive neurotransmitters in the spinal cord, possibly by disrupting alpha 2 -delta containing-calcium channel trafficking and/or reducing calcium currents.

Evidence from other animal models of nerve damage and persistent pain suggest the anti-nociceptive activities of pregabalin may also be mediated through interactions with descending noradrenergic and serotonergic pathways originating from the brainstem that modulate pain transmission in the spinal cord.

While pregabalin is a structural derivative of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), it does not bind directly to GABA A , GABA B , or benzodiazepine receptors, does not augment GABA A responses in cultured neurons, does not alter rat brain GABA concentration or have acute effects on GABA uptake or degradation.

However, in cultured neurons prolonged application of pregabalin increases the density of GABA transporter protein and increases the rate of functional GABA transport.

Pregabalin does not block sodium channels, is not active at opiate receptors, and does not alter cyclooxygenase enzyme activity.

It is inactive at serotonin and dopamine receptors and does not inhibit dopamine, serotonin, or noradrenaline reuptake.

INDICATIONS AND USAGE

1 LYRICA is indicated for: Management of neuropathic pain associated with diabetic peripheral neuropathy Management of postherpetic neuralgia Adjunctive therapy for adult patients with partial onset seizures Management of fibromyalgia Management of neuropathic pain associated with spinal cord injury LYRICA is indicated for: Neuropathic pain associated with diabetic peripheral neuropathy (DPN) ( 1 ) Postherpetic neuralgia (PHN) ( 1 ) Adjunctive therapy for adult patients with partial onset seizures ( 1 ) Fibromyalgia ( 1 ) Neuropathic pain associated with spinal cord injury ( 1 )

PEDIATRIC USE

8.4 Pediatric Use The safety and efficacy of pregabalin in pediatric patients have not been established.

Fibromyalgia A 15-week, placebo-controlled trial was conducted with 107 pediatric patients with fibromyalgia, ages 12 through 17 years, at LYRICA total daily doses of 75–450 mg per day.

The primary efficacy endpoint of change from baseline to Week 15 in mean pain intensity (derived from an 11-point numeric rating scale) showed numerically greater improvement for the pregabalin-treated patients compared to placebo-treated patients, but did not reach statistical significance.

The most frequently observed adverse reactions in the clinical trial included dizziness, nausea, headache, weight increased, and fatigue.

The overall safety profile in adolescents was similar to that observed in adults with fibromyalgia.

Juvenile Animal Data In studies in which pregabalin (50 to 500 mg/kg) was orally administered to young rats from early in the postnatal period (Postnatal Day 7) through sexual maturity, neurobehavioral abnormalities (deficits in learning and memory, altered locomotor activity, decreased auditory startle responding and habituation) and reproductive impairment (delayed sexual maturation and decreased fertility in males and females) were observed at doses greater than or equal to 50 mg/kg.

The neurobehavioral changes of acoustic startle persisted at greater than or equal to 250 mg/kg and locomotor activity and water maze performance at greater than or equal to 500 mg/kg in animals tested after cessation of dosing and, thus, were considered to represent long-term effects.

The low effect dose for developmental neurotoxicity and reproductive impairment in juvenile rats (50 mg/kg) was associated with a plasma pregabalin exposure (AUC) approximately equal to human exposure at the maximum recommended dose of 600 mg/day.

A no-effect dose was not established.

PREGNANCY

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to LYRICA during pregnancy.

To provide information regarding the effects of in utero exposure to LYRICA, physicians are advised to recommend that pregnant patients taking LYRICA enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry.

This can be done by calling the toll free number 1-888-233-2334, and must be done by patients themselves.

Information on the registry can also be found at the website http://www.aedpregnancyregistry.org/.

Risk Summary There are no adequate and well-controlled studies with LYRICA in pregnant women.

However, in animal reproduction studies, increased incidences of fetal structural abnormalities and other manifestations of developmental toxicity, including skeletal malformations, retarded ossification, and decreased fetal body weight were observed in the offspring of rats and rabbits given pregabalin orally during organogenesis, at doses that produced plasma pregabalin exposures (AUC) greater than or equal to 16 times human exposure at the maximum recommended dose (MRD) of 600 mg/day [see Data ] .

In an animal development study, lethality, growth retardation, and nervous and reproductive system functional impairment were observed in the offspring of rats given pregabalin during gestation and lactation.

The no-effect dose for developmental toxicity was approximately twice the human exposure at MRD.

The background risk of major birth defects and miscarriage for the indicated populations are unknown.

However, the background risk in the U.S.

general population of major birth defects is 2–4% and of miscarriage is 15–20% of clinically recognized pregnancies.

Advise pregnant women of the potential risk to a fetus.

Data Animal Data When pregnant rats were given pregabalin (500, 1250, or 2500 mg/kg) orally throughout the period of organogenesis, incidences of specific skull alterations attributed to abnormally advanced ossification (premature fusion of the jugal and nasal sutures) were increased at greater than or equal to 1250 mg/kg, and incidences of skeletal variations and retarded ossification were increased at all doses.

Fetal body weights were decreased at the highest dose.

The low dose in this study was associated with a plasma exposure (AUC) approximately 17 times human exposure at the MRD of 600 mg/day.

A no-effect dose for rat embryo-fetal developmental toxicity was not established.

When pregnant rabbits were given LYRICA (250, 500, or 1250 mg/kg) orally throughout the period of organogenesis, decreased fetal body weight and increased incidences of skeletal malformations, visceral variations, and retarded ossification were observed at the highest dose.

The no-effect dose for developmental toxicity in rabbits (500 mg/kg) was associated with a plasma exposure approximately 16 times human exposure at the MRD.

In a study in which female rats were dosed with LYRICA (50, 100, 250, 1250, or 2500 mg/kg) throughout gestation and lactation, offspring growth was reduced at greater than or equal to 100 mg/kg and offspring survival was decreased at greater than or equal to 250 mg/kg.

The effect on offspring survival was pronounced at doses greater than or equal to 1250 mg/kg, with 100% mortality in high-dose litters.

When offspring were tested as adults, neurobehavioral abnormalities (decreased auditory startle responding) were observed at greater than or equal to 250 mg/kg and reproductive impairment (decreased fertility and litter size) was seen at 1250 mg/kg.

The no-effect dose for pre- and postnatal developmental toxicity in rats (50 mg/kg) produced a plasma exposure approximately 2 times human exposure at the MRD.

In the prenatal-postnatal study in rats, pregabalin prolonged gestation and induced dystocia at exposures greater than or equal to 50 times the mean human exposure (AUC (0–24) of 123 µg∙hr/mL) at theMRD.

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS Angioedema (e.g., swelling of the throat, head and neck) can occur, and may be associated with life-threatening respiratory compromise requiring emergency treatment.

Discontinue LYRICA immediately in these cases.

( 5.1 ) Hypersensitivity reactions (e.g.

hives, dyspnea, and wheezing) can occur.

Discontinue LYRICA immediately in these patients.

( 5.2 ) Increased seizure frequency may occur in patients with seizure disorders if LYRICA is rapidly discontinued.

Withdraw LYRICA gradually over a minimum of 1 week.

( 5.3 ) Antiepileptic drugs, including LYRICA, increase the risk of suicidal thoughts or behavior.

( 5.4 ) LYRICA may cause peripheral edema.

Exercise caution when co-administering LYRICA and thiazolidinedione antidiabetic agents.

( 5.5 ) LYRICA may cause dizziness and somnolence and impair patients’ ability to drive or operate machinery.( 5.6 ) 5.1 Angioedema There have been postmarketing reports of angioedema in patients during initial and chronic treatment with LYRICA.

Specific symptoms included swelling of the face, mouth (tongue, lips, and gums), and neck (throat and larynx).

There were reports of life-threatening angioedema with respiratory compromise requiring emergency treatment.

Discontinue LYRICA immediately in patients with these symptoms.

Exercise caution when prescribing LYRICA to patients who have had a previous episode of angioedema.

In addition, patients who are taking other drugs associated with angioedema (e.g., angiotensin converting enzyme inhibitors [ACE-inhibitors]) may be at increased risk of developing angioedema.

5.2 Hypersensitivity There have been postmarketing reports of hypersensitivity in patients shortly after initiation of treatment with LYRICA.

Adverse reactions included skin redness, blisters, hives, rash, dyspnea, and wheezing.

Discontinue LYRICA immediately in patients with these symptoms.

5.3 Withdrawal of Antiepileptic Drugs (AEDs) As with all AEDs, withdraw LYRICA gradually to minimize the potential of increased seizure frequency in patients with seizure disorders.

If LYRICA is discontinued, taper the drug gradually over a minimum of 1 week.

5.4 Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including LYRICA, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication.

Monitor patients treated with any AED for any indication for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior.

Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo.

In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated.

There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide.

The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed.

Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed.

The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed.

The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication.

The risk did not vary substantially by age (5–100 years) in the clinical trials analyzed.

Table 2 shows absolute and relative risk by indication for all evaluated AEDs.

Table 2.

Risk by indication for antiepileptic drugs in the pooled analysis Indication Placebo Patients with Events Per 1000 Patients Drug Patients with Events Per 1000 Patients Relative Risk: Incidence of Events in Drug Patients/Incidence in Placebo Patients Risk Difference: Additional Drug Patients with Events Per 1000 Patients Epilepsy 1.0 3.4 3.5 2.4 Psychiatric 5.7 8.5 1.5 2.9 Other 1.0 1.8 1.9 0.9 Total 2.4 4.3 1.8 1.9 The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications.

Anyone considering prescribing LYRICA or any other AED must balance the risk of suicidal thoughts or behavior with the risk of untreated illness.

Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior.

Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.

Inform patients, their caregivers, and families that LYRICA and other AEDs increase the risk of suicidal thoughts and behavior and advise them of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm.

Report behaviors of concern immediately to healthcare providers.

5.5 Peripheral Edema LYRICA treatment may cause peripheral edema.

In short-term trials of patients without clinically significant heart or peripheral vascular disease, there was no apparent association between peripheral edema and cardiovascular complications such as hypertension or congestive heart failure.

Peripheral edema was not associated with laboratory changes suggestive of deterioration in renal or hepatic function.

In controlled clinical trials the incidence of peripheral edema was 6% in the LYRICA group compared with 2% in the placebo group.

In controlled clinical trials, 0.5% of LYRICA patients and 0.2% placebo patients withdrew due to peripheral edema.

Higher frequencies of weight gain and peripheral edema were observed in patients taking both LYRICA and a thiazolidinedione antidiabetic agent compared to patients taking either drug alone.

The majority of patients using thiazolidinedione antidiabetic agents in the overall safety database were participants in studies of pain associated with diabetic peripheral neuropathy.

In this population, peripheral edema was reported in 3% (2/60) of patients who were using thiazolidinedione antidiabetic agents only, 8% (69/859) of patients who were treated with LYRICA only, and 19% (23/120) of patients who were on both LYRICA and thiazolidinedione antidiabetic agents.

Similarly, weight gain was reported in 0% (0/60) of patients on thiazolidinediones only; 4% (35/859) of patients on LYRICA only; and 7.5% (9/120) of patients on both drugs.

As the thiazolidinedione class of antidiabetic drugs can cause weight gain and/or fluid retention, possibly exacerbating or leading to heart failure, exercise caution when co-administering LYRICA and these agents.

Because there are limited data on congestive heart failure patients with New York Heart Association (NYHA) Class III or IV cardiac status, exercise caution when using LYRICA in these patients.

5.6 Dizziness and Somnolence LYRICA may cause dizziness and somnolence.

Inform patients that LYRICA-related dizziness and somnolence may impair their ability to perform tasks such as driving or operating machinery [see Patient Counseling Information (17.5) ] .

In the LYRICA controlled trials, dizziness was experienced by 30% of LYRICA-treated patients compared to 8% of placebo-treated patients; somnolence was experienced by 23% of LYRICA-treated patients compared to 8% of placebo-treated patients.

Dizziness and somnolence generally began shortly after the initiation of LYRICA therapy and occurred more frequently at higher doses.

Dizziness and somnolence were the adverse reactions most frequently leading to withdrawal (4% each) from controlled studies.

In LYRICA-treated patients reporting these adverse reactions in short-term, controlled studies, dizziness persisted until the last dose in 30% and somnolence persisted until the last dose in 42% of patients [see Drug Interactions (7) ] .

5.7 Weight Gain LYRICA treatment may cause weight gain.

In LYRICA controlled clinical trials of up to 14 weeks, a gain of 7% or more over baseline weight was observed in 9% of LYRICA-treated patients and 2% of placebo-treated patients.

Few patients treated with LYRICA (0.3%) withdrew from controlled trials due to weight gain.

LYRICA associated weight gain was related to dose and duration of exposure, but did not appear to be associated with baseline BMI, gender, or age.

Weight gain was not limited to patients with edema [see Warnings and Precautions (5.5) ] .

Although weight gain was not associated with clinically important changes in blood pressure in short-term controlled studies, the long-term cardiovascular effects of LYRICA-associated weight gain are unknown.

Among diabetic patients, LYRICA-treated patients gained an average of 1.6 kg (range: -16 to 16 kg), compared to an average 0.3 kg (range: -10 to 9 kg) weight gain in placebo patients.

In a cohort of 333 diabetic patients who received LYRICA for at least 2 years, the average weight gain was 5.2 kg.

While the effects of LYRICA-associated weight gain on glycemic control have not been systematically assessed, in controlled and longer-term open label clinical trials with diabetic patients, LYRICA treatment did not appear to be associated with loss of glycemic control (as measured by HbA 1C ).

5.8 Abrupt or Rapid Discontinuation Following abrupt or rapid discontinuation of LYRICA, some patients reported symptoms including insomnia, nausea, headache, anxiety, hyperhidrosis, and diarrhea.

Taper LYRICA gradually over a minimum of 1 week rather than discontinuing the drug abruptly.

5.9 Tumorigenic Potential In standard preclinical in vivo lifetime carcinogenicity studies of LYRICA, an unexpectedly high incidence of hemangiosarcoma was identified in two different strains of mice [see Nonclinical Toxicology (13.1) ] .

The clinical significance of this finding is unknown.

Clinical experience during LYRICA’s premarketing development provides no direct means to assess its potential for inducing tumors in humans.

In clinical studies across various patient populations, comprising 6396 patient-years of exposure in patients greater than 12 years of age, new or worsening-preexisting tumors were reported in 57 patients.

Without knowledge of the background incidence and recurrence in similar populations not treated with LYRICA, it is impossible to know whether the incidence seen in these cohorts is or is not affected by treatment.

5.10 Ophthalmological Effects In controlled studies, a higher proportion of patients treated with LYRICA reported blurred vision (7%) than did patients treated with placebo (2%), which resolved in a majority of cases with continued dosing.

Less than 1% of patients discontinued LYRICA treatment due to vision-related events (primarily blurred vision).

Prospectively planned ophthalmologic testing, including visual acuity testing, formal visual field testing and dilated funduscopic examination, was performed in over 3600 patients.

In these patients, visual acuity was reduced in 7% of patients treated with LYRICA, and 5% of placebo-treated patients.

Visual field changes were detected in 13% of LYRICA-treated, and 12% of placebo-treated patients.

Funduscopic changes were observed in 2% of LYRICA-treated and 2% of placebo-treated patients.

Although the clinical significance of the ophthalmologic findings is unknown, inform patients to notify their physician if changes in vision occur.

If visual disturbance persists, consider further assessment.

Consider more frequent assessment for patients who are already routinely monitored for ocular conditions [see Patient Counseling Information (17.8) ] .

5.11 Creatine Kinase Elevations LYRICA treatment was associated with creatine kinase elevations.

Mean changes in creatine kinase from baseline to the maximum value were 60 U/L for LYRICA-treated patients and 28 U/L for the placebo patients.

In all controlled trials across multiple patient populations, 1.5% of patients on LYRICA and 0.7% of placebo patients had a value of creatine kinase at least three times the upper limit of normal.

Three LYRICA treated subjects had events reported as rhabdomyolysis in premarketing clinical trials.

The relationship between these myopathy events and LYRICA is not completely understood because the cases had documented factors that may have caused or contributed to these events.

Instruct patients to promptly report unexplained muscle pain, tenderness, or weakness, particularly if these muscle symptoms are accompanied by malaise or fever.

Discontinue treatment with LYRICA if myopathy is diagnosed or suspected or if markedly elevated creatine kinase levels occur.

5.12 Decreased Platelet Count LYRICA treatment was associated with a decrease in platelet count.

LYRICA-treated subjects experienced a mean maximal decrease in platelet count of 20 × 10 3 /µL, compared to 11 × 10 3 /µL in placebo patients.

In the overall database of controlled trials, 2% of placebo patients and 3% of LYRICA patients experienced a potentially clinically significant decrease in platelets, defined as 20% below baseline value and less than 150 × 10 3 /µL.

A single LYRICA treated subject developed severe thrombocytopenia with a platelet count less than 20 × 10 3 / µL.

In randomized controlled trials, LYRICA was not associated with an increase in bleeding-related adverse reactions.

5.13 PR Interval Prolongation LYRICA treatment was associated with PR interval prolongation.

In analyses of clinical trial ECG data, the mean PR interval increase was 3–6 msec at LYRICA doses greater than or equal to 300 mg/day.

This mean change difference was not associated with an increased risk of PR increase greater than or equal to 25% from baseline, an increased percentage of subjects with on-treatment PR greater than 200 msec, or an increased risk of adverse reactions of second or third degree AV block.

Subgroup analyses did not identify an increased risk of PR prolongation in patients with baseline PR prolongation or in patients taking other PR prolonging medications.

However, these analyses cannot be considered definitive because of the limited number of patients in these categories.

INFORMATION FOR PATIENTS

17 PATIENT COUNSELING INFORMATION 17.1 Medication Guide Inform patients of the availability of a Medication Guide, and instruct them to read the Medication Guide prior to taking LYRICA.

Instruct patients to take LYRICA only as prescribed.

17.2 Angioedema Advise patients that LYRICA may cause angioedema, with swelling of the face, mouth (lip, gum, tongue) and neck (larynx and pharynx) that can lead to life-threatening respiratory compromise.

Instruct patients to discontinue LYRICA and immediately seek medical care if they experience these symptoms [ see Warnings and Precautions (5.1) ].

17.3 Hypersensitivity Advise patients that LYRICA has been associated with hypersensitivity reactions such as wheezing, dyspnea, rash, hives, and blisters.

Instruct patients to discontinue LYRICA and immediately seek medical care if they experience these symptoms [see Warnings and Precautions (5.2) ].

17.4 Suicidal Thinking and Behavior Patients, their caregivers, and families should be counseled that AEDs, including LYRICA, may increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm.

Report behaviors of concern immediately to healthcare providers [see Warnings and Precautions (5.4) ] .

17.5 Dizziness and Somnolence Counsel patients that LYRICA may cause dizziness, somnolence, blurred vision and other CNS signs and symptoms.

Accordingly, advise patients not to drive, operate complex machinery, or engage in other hazardous activities until they have gained sufficient experience on LYRICA to gauge whether or not it affects their mental, visual, and/or motor performance adversely.

[see Warnings and Precautions (5.6) ] .

17.6 Weight Gain and Edema Counsel patients that LYRICA may cause edema and weight gain.

Advise patients that concomitant treatment with LYRICA and a thiazolidinedione antidiabetic agent may lead to an additive effect on edema and weight gain.

For patients with preexisting cardiac conditions, this may increase the risk of heart failure.

[see Warnings and Precautions (5.5 and 5.7) ] .

17.7 Abrupt or Rapid Discontinuation Advise patients to take LYRICA as prescribed.

Abrupt or rapid discontinuation may result in insomnia, nausea, headache, anxiety, hyperhidrosis, or diarrhea.

[see Warnings and Precautions (5.8) ] .

17.8 Ophthalmological Effects Counsel patients that LYRICA may cause visual disturbances.

Inform patients that if changes in vision occur, they should notify their physician [see Warnings and Precautions (5.10) ] .

17.9 Creatine Kinase Elevations Instruct patients to promptly report unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever.

[see Warnings and Precautions (5.11) ] .

17.10 CNS Depressants Inform patients who require concomitant treatment with central nervous system depressants such as opiates or benzodiazepines that they may experience additive CNS side effects, such as somnolence [see Warnings and Precautions (5.6) and Drug Interactions (7) ] .

17.11 Alcohol Tell patients to avoid consuming alcohol while taking LYRICA, as LYRICA may potentiate the impairment of motor skills and sedating effects of alcohol.

17.12 Pregnancy There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to LYRICA during pregnancy [see Use in Specific Populations (8.1) ] .

17.13 Lactation Advise nursing mothers that breastfeeding is not recommended during treatment with LYRICA [ see Use in Specific Populations (8.2) ] .

17.14 Male Fertility Inform men being treated with LYRICA who plan to father a child of the potential risk of male-mediated teratogenicity.

In preclinical studies in rats, pregabalin was associated with an increased risk of male-mediated teratogenicity.

The clinical significance of this finding is uncertain [see Nonclinical Toxicology (13.1) and Use in specific populations (8.3) ] .

17.15 Dermatopathy Instruct diabetic patients to pay particular attention to skin integrity while being treated with LYRICA.

Some animals treated with pregabalin developed skin ulcerations, although no increased incidence of skin lesions associated with LYRICA was observed in clinical trials [see Nonclinical Toxicology (13.2) ] .

DOSAGE AND ADMINISTRATION

2 LYRICA is given orally with or without food.

When discontinuing LYRICA, taper gradually over a minimum of 1 week.

For all indications, begin dosing at 150 mg/day.

( 2.1 , 2.2 , 2.3 , 2.4 , 2.5 ) Dosing recommendations: INDICATION Dosing Regimen Maximum Dose DPN Pain ( 2.1 ) 3 divided doses per day 300 mg/day within 1 week PHN ( 2.2 ) 2 or 3 divided doses per day 300 mg/day within 1 week.

Maximum dose of 600 mg/day.

Adjunctive Therapy for Adult Patients with Partial Onset Seizures ( 2.3 ) 2 or 3 divided doses per day Maximum dose of 600 mg/day.

Fibromyalgia ( 2.4 ) 2 divided doses per day 300 mg/day within 1 week.

Maximum dose of 450 mg/day.

Neuropathic Pain Associated with Spinal Cord Injury ( 2.5 ) 2 divided doses per day 300 mg/day within 1 week.

Maximum dose of 600 mg/day.

Dose should be adjusted in patients with reduced renal function.

( 2.6 ) Oral Solution Concentration and Dispensing ( 2.7 ) 2.1 Neuropathic Pain Associated with Diabetic Peripheral Neuropathy The maximum recommended dose of LYRICA is 100 mg three times a day (300 mg/day) in patients with creatinine clearance of at least 60 mL/min.

Begin dosing at 50 mg three times a day (150 mg/day).

The dose may be increased to 300 mg/day within 1 week based on efficacy and tolerability.

Because LYRICA is eliminated primarily by renal excretion, adjust the dose in patients with reduced renal function [see Dosage and Administration (2.6) ] .

Although LYRICA was also studied at 600 mg/day, there is no evidence that this dose confers additional significant benefit and this dose was less well tolerated.

In view of the dose-dependent adverse reactions, treatment with doses above 300 mg/day is not recommended [see Adverse Reactions (6.1) ] .

2.2 Postherpetic Neuralgia The recommended dose of LYRICA is 75 to 150 mg two times a day, or 50 to 100 mg three times a day (150 to 300 mg/day) in patients with creatinine clearance of at least 60 mL/min.

Begin dosing at 75 mg two times a day, or 50 mg three times a day (150 mg/day).

The dose may be increased to 300 mg/day within 1 week based on efficacy and tolerability.

Because LYRICA is eliminated primarily by renal excretion, adjust the dose in patients with reduced renal function [see Dosage and Administration (2.6) ] .

Patients who do not experience sufficient pain relief following 2 to 4 weeks of treatment with 300 mg/day, and who are able to tolerate LYRICA, may be treated with up to 300 mg two times a day, or 200 mg three times a day (600 mg/day).

In view of the dose-dependent adverse reactions and the higher rate of treatment discontinuation due to adverse reactions, reserve dosing above 300 mg/day for those patients who have on-going pain and are tolerating 300 mg daily [see Adverse Reactions (6.1) ] .

2.3 Adjunctive Therapy for Adult Patients with Partial Onset Seizures LYRICA at doses of 150 to 600 mg/day has been shown to be effective as adjunctive therapy in the treatment of partial onset seizures in adults.

Both the efficacy and adverse event profiles of LYRICA have been shown to be dose-related.

Administer the total daily dose in two or three divided doses.

In general, it is recommended that patients be started on a total daily dose no greater than 150 mg/day (75 mg two times a day, or 50 mg three times a day).

Based on individual patient response and tolerability, the dose may be increased to a maximum dose of 600 mg/day.

Because LYRICA is eliminated primarily by renal excretion, adjust the dose in patients with reduced renal function [see Dosage and Administration (2.6) ] .

The effect of dose escalation rate on the tolerability of LYRICA has not been formally studied.

The efficacy of add-on LYRICA in patients taking gabapentin has not been evaluated in controlled trials.

Consequently, dosing recommendations for the use of LYRICA with gabapentin cannot be offered.

2.4 Management of Fibromyalgia The recommended dose of LYRICA for fibromyalgia is 300 to 450 mg/day.

Begin dosing at 75 mg two times a day (150 mg/day).

The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability.

Patients who do not experience sufficient benefit with 300 mg/day may be further increased to 225 mg two times a day (450 mg/day).

Although LYRICA was also studied at 600 mg/day, there is no evidence that this dose confers additional benefit and this dose was less well tolerated.

In view of the dose-dependent adverse reactions, treatment with doses above 450 mg/day is not recommended [see Adverse Reactions (6.1) ] .

Because LYRICA is eliminated primarily by renal excretion, adjust the dose in patients with reduced renal function [see Dosage and Administration (2.6) ] .

2.5 Neuropathic Pain Associated with Spinal Cord Injury The recommended dose range of LYRICA for the treatment of neuropathic pain associated with spinal cord injury is 150 to 600 mg/day.

The recommended starting dose is 75 mg two times a day (150 mg/day).

The dose may be increased to 150 mg two times a day (300 mg/day) within 1 week based on efficacy and tolerability.

Patients who do not experience sufficient pain relief after 2 to 3 weeks of treatment with 150 mg two times a day and who tolerate LYRICA may be treated with up to 300 mg two times a day [see Clinical Studies (14.5) ] .

Because LYRICA is eliminated primarily by renal excretion, adjust the dose in patients with reduced renal function [see Dosage and Administration (2.6) ] .

2.6 Patients with Renal Impairment In view of dose-dependent adverse reactions and since LYRICA is eliminated primarily by renal excretion, adjust the dose in patients with reduced renal function.

Base the dose adjustment in patients with renal impairment on creatinine clearance (CLcr), as indicated in Table 1.

To use this dosing table, an estimate of the patient’s CLcr in mL/min is needed.

CLcr in mL/min may be estimated from serum creatinine (mg/dL) determination using the Cockcroft and Gault equation: Next, refer to the Dosage and Administration section to determine the recommended total daily dose based on indication, for a patient with normal renal function (CLcr greater than or equal to 60 mL/min).

Then refer to Table 1 to determine the corresponding renal adjusted dose.

(For example: A patient initiating LYRICA therapy for postherpetic neuralgia with normal renal function (CLcr greater than or equal to 60 mL/min), receives a total daily dose of 150 mg/day pregabalin.

Therefore, a renal impaired patient with a CLcr of 50 mL/min would receive a total daily dose of 75 mg/day pregabalin administered in two or three divided doses.) For patients undergoing hemodialysis, adjust the pregabalin daily dose based on renal function.

In addition to the daily dose adjustment, administer a supplemental dose immediately following every 4-hour hemodialysis treatment (see Table 1 ).

Table 1.

Pregabalin Dosage Adjustment Based on Renal Function Creatinine Clearance (CLcr) (mL/min) Total Pregabalin Daily Dose (mg/day) Total daily dose (mg/day) should be divided as indicated by dose regimen to provide mg/dose.

calcitriol 0.25 MCG Oral Capsule

WARNINGS

Overdosage of any form of vitamin D is dangerous (see OVERDOSAGE ).

Progressive hypercalcemia due to overdosage of vitamin D and its metabolites may be so severe as to require emergency attention.

Chronic hypercalcemia can lead to generalized vascular calcification, nephrocalcinosis and other soft-tissue calcification.

The serum calcium times phosphate (Ca x P) product should not be allowed to exceed 70 mg 2 /dL 2 .

Radiographic evaluation of suspect anatomical regions may be useful in the early detection of this condition.

Calcitriol is the most potent metabolite of vitamin D available.

The administration of calcitriol to patients in excess of their daily requirements can cause hypercalcemia, hypercalciuria, and hyperphosphatemia.

Therefore, pharmacologic doses of vitamin D and its derivatives should be withheld during calcitriol treatment to avoid possible additive effects and hypercalcemia.

If treatment is switched from ergocalciferol (vitamin D 2 ) to calcitriol, it may take several months for the ergocalciferol level in the blood to return to the baseline value (see OVERDOSAGE ).

Calcitriol increases inorganic phosphate levels in serum.

While this is desirable in patients with hypophosphatemia, caution is called for in patients with renal failure because of the danger of ectopic calcification.

A non-aluminum phosphate-binding compound and a low-phosphate diet should be used to control serum phosphorus levels in patients undergoing dialysis.

Magnesium-containing preparations (eg, antacids) and calcitriol should not be used concomitantly in patients on chronic renal dialysis because such use may lead to the development of hypermagnesemia.

Studies in dogs and rats given calcitriol for up to 26 weeks have shown that small increases of calcitriol above endogenous levels can lead to abnormalities of calcium metabolism with the potential for calcification of many tissues in the body.

DRUG INTERACTIONS

Drug Interactions Cholestyramine Cholestyramine has been reported to reduce intestinal absorption of fat-soluble vitamins; as such it may impair intestinal absorption of calcitriol (see WARNINGS and PRECAUTIONS : General ).

Phenytoin/Phenobarbital The coadministration of phenytoin or phenobarbital will not affect plasma concentrations of calcitriol, but may reduce endogenous plasma levels of 25(OH)D 3 by accelerating metabolism.

Since blood level of calcitriol will be reduced, higher doses of calcitriol may be necessary if these drugs are administered simultaneously.

Thiazides Thiazides are known to induce hypercalcemia by the reduction of calcium excretion in urine.

Some reports have shown that the concomitant administration of thiazides with calcitriol causes hypercalcemia.

Therefore, precaution should be taken when coadministration is necessary.

Digitalis Calcitriol dosage must be determined with care in patients undergoing treatment with digitalis, as hypercalcemia in such patients may precipitate cardiac arrhythmias (see PRECAUTIONS : General ).

Ketoconazole Ketoconazole may inhibit both synthetic and catabolic enzymes of calcitriol.

Reductions in serum endogenous calcitriol concentrations have been observed following the administration of 300 mg/day to 1200 mg/day ketoconazole for a week to healthy men.

However, in vivo drug interaction studies of ketoconazole with calcitriol have not been investigated.

Corticosteroids A relationship of functional antagonism exists between vitamin D analogues, which promote calcium absorption, and corticosteroids, which inhibit calcium absorption.

Phosphate-Binding Agents Since calcitriol also has an effect on phosphate transport in the intestine, kidneys and bones, the dosage of phosphate-binding agents must be adjusted in accordance with the serum phosphate concentration.

Vitamin D Since calcitriol is the most potent active metabolite of vitamin D3, pharmacological doses of vitamin D and its derivatives should be withheld during treatment with calcitriol to avoid possible additive effects and hypercalcemia (see WARNINGS ).

Calcium Supplements: Uncontrolled intake of additional calcium-containing preparations should be avoided (see PRECAUTIONS : General ).

Magnesium Magnesium-containing preparations (eg, antacids) may cause hypermagnesemia and should therefore not be taken during therapy with calcitriol by patients on chronic renal dialysis.

Carcinogenesis, Mutagenesis and Impairment of Fertility Long-term studies in animals have not been conducted to evaluate the carcinogenic potential of calcitriol.

Calcitriol is not mutagenic in vitro in the Ames Test, nor is it genotoxic in vivo in the Mouse Micronucleus Test.

No significant effects of calcitriol on fertility and/or general reproductive performances were observed in a Segment I study in rats at doses of up to 0.3 mcg/kg (approximately 3 times the maximum recommended dose based on body surface area).

OVERDOSAGE

Administration of calcitriol to patients in excess of their daily requirements can cause hypercalcemia, hypercalciuria and hyperphosphatemia.

Since calcitriol is a derivative of vitamin D, the signs and symptoms of overdose are the same as for an overdose of vitamin D (see ADVERSE REACTIONS ).

High intake of calcium and phosphate concomitant with calcitriol may lead to similar abnormalities.

The serum calcium times phosphate (Ca x P) product should not be allowed to exceed 70 mg2/dL2.

High levels of calcium in the dialysate bath may contribute to the hypercalcemia (see WARNINGS ).

Treatment of Hypercalcemia and Overdosage in Dialysis Patients and Hypoparathyroidism Patients General treatment of hypercalcemia (greater than 1 mg/dL above the upper limit of the normal range) consists of immediate discontinuation of calcitriol therapy, institution of a low-calcium diet and withdrawal of calcium supplements.

Serum calcium levels should be determined daily until normocalcemia ensues.

Hypercalcemia frequently resolves in 2 to 7 days.

When serum calcium levels have returned to within normal limits, calcitriol therapy may be reinstituted at a dose of 0.25 mcg/day less than prior therapy.

Serum calcium levels should be obtained at least twice weekly after all dosage changes and subsequent dosage titration.

In dialysis patients, persistent or markedly elevated serum calcium levels may be corrected by dialysis against a calcium-free dialysate.

Treatment of Hypercalcemia and Overdosage in Predialysis Patients If hypercalcemia ensues (greater than 1 mg/dL above the upper limit of the normal range), adjust dosage to achieve normocalcemia by reducing calcitriol therapy from 0.5 mcg to 0.25 mcg daily.

If the patient is receiving a therapy of 0.25 mcg daily, discontinue calcitriol until patient becomes normocalcemic.

Calcium supplements should also be reduced or discontinued.

Serum calcium levels should be determined 1 week after withdrawal of calcium supplements.

If serum calcium levels have returned to normal, calcitriol therapy may be reinstituted at a dosage of 0.25 mcg/day if previous therapy was at a dosage of 0.5 mcg/day.

If calcitriol therapy was previously administered at a dosage of 0.25 mcg/day, calcitriol therapy may be reinstituted at a dosage of 0.25 mcg every other day.

If hypercalcemia is persistent at the reduced dosage, serum PTH should be measured.

If serum PTH is normal, discontinue calcitriol therapy and monitor patient in 3 months’ time.

Treatment of Hyperphosphatemia in Predialysis Patients If serum phosphorus levels exceed 5 mg/dL to 5.5 mg/dL, a calcium-containing phosphate-binding agent (ie, calcium carbonate or calcium acetate) should be taken with meals.

Serum phosphorus levels should be determined as described earlier (see PRECAUTIONS : Laboratory Tests ).

Aluminum-containing gels should be used with caution as phosphate-binding agents because of the risk of slow aluminum accumulation.

Treatment of Accidental Overdosage of Calcitriol The treatment of acute accidental overdosage of calcitriol should consist of general supportive measures.

If drug ingestion is discovered within a relatively short time, induction of emesis or gastric lavage may be of benefit in preventing further absorption.

If the drug has passed through the stomach, the administration of mineral oil may promote its fecal elimination.

Serial serum electrolyte determinations (especially calcium), rate of urinary calcium excretion and assessment of eIectrocardiographic abnormalities due to hypercalcemia should be obtained.

Such monitoring is critical in patients receiving digitalis.

Discontinuation of supplemental calcium and a low-calcium diet are also indicated in accidental overdosage.

Due to the relatively short duration of the pharmacological action of calcitriol, further measures are probably unnecessary.

Should, however, persistent and markedly elevated serum calcium levels occur, there are a variety of therapeutic alternatives which may be considered, depending on the patient’s underlying condition.

These include the use of drugs such as phosphates and corticosteroids as well as measures to induce an appropriate forced diuresis.

The use of peritoneal dialysis against a calcium-free dialysate has also been reported.

GERIATRIC USE

Geriatric Use Clinical studies of calcitriol did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

INDICATIONS AND USAGE

Predialysis Patients Calcitriol Capsules are indicated in the management of secondary hyperparathyroidism and resultant metabolic bone disease in patients with moderate to severe chronic renal failure (Ccr 15 to 55 mL/min) not yet on dialysis.

In children, the creatinine clearance value must be corrected for a surface area of 1.73 square meters.

A serum iPTH level of ≥100 pg/mL is strongly suggestive of secondary hyperparathyroidism.

Dialysis Patients Calcitriol Capsules are indicated in the management of hypocalcemia and the resultant metabolic bone disease in patients undergoing chronic renal dialysis.

In these patients, calcitriol administration enhances calcium absorption, reduces serum alkaline phosphatase levels, and may reduce elevated parathyroid hormone levels and the histological manifestations of osteitis fibrosa cystica and defective mineralization.

Hypoparathyroidism Patients Calcitriol Capsules are also indicated in the management of hypocalcemia and its clinical manifestations in patients with postsurgical hypoparathyroidism, idiopathic hypoparathyroidism, and pseudohypoparathyroidism.

PEDIATRIC USE

Pediatric Use Safety and effectiveness of calcitriol in pediatric patients undergoing dialysis have not been established.

The safety and effectiveness of calcitriol in pediatric predialysis patients is based on evidence from adequate and well-controlled studies of calcitriol in adults with predialysis chronic renal failure and additional supportive data from non-placebo controlled studies in pediatric patients.

Dosing guidelines have not been established for pediatric patients under 1 year of age with hypoparathyroidism or for pediatric patients less than 6 years of age with pseudohypoparathyroidism (see DOSAGE AND ADMINISTRATION : Hypoparathyroidism ).

Oral doses of calcitriol ranging from 10 to 55 ng/kg/day have been shown to improve calcium homeostasis and bone disease in pediatric patients with chronic renal failure for whom hemodialysis is not yet required (predialysis).

Long-term calcitriol therapy is well tolerated by pediatric patients.

The most common safety issues are mild, transient episodes of hypercalcemia, hyperphosphatemia, and increases in the serum calcium times phosphate (Ca x P) product which are managed effectively by dosage adjustment or temporary discontinuation of the vitamin D derivative.

PREGNANCY

Pregnancy Teratogenic Effects Pregnancy Category C Calcitriol has been found to be teratogenic in rabbits when given at doses of 0.08 and 0.3 mcg/kg (approximately 2 and 6 times the maximum recommended dose based on mg/m 2 ).

All 15 fetuses in 3 litters at these doses showed external and skeletal abnormalities.

However, none of the other 23 litters (156 fetuses) showed external and skeletal abnormalities compared with controls.

Teratogenicity studies in rats at doses up to 0.45 mcg/kg (approximately 5 times maximum recommended dose based on mg/m 2 ) showed no evidence of teratogenic potential.

There are no adequate and well-controlled studies in pregnant women.

Calcitriol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nonteratogenic Effects In the rabbit, dosages of 0.3 mcg/kg/day (approximately 6 times maximum recommended dose based on surface area) administered on days 7 to 18 of ges-tation resulted in 19% maternal mortality, a decrease in mean fetal body weight and a reduced number of newborn surviving to 24 hours.

A study of perinatal and postnatal development in rats resulted in hypercalcemia in the offspring of dams given calcitriol at doses of 0.08 or 0.3 mcg/kg/day (approximately 1 and 3 times the maximum recommended dose based on mg/m 2 ), hypercalcemia and hypophosphatemia in dams given calcitriol at a dose of 0.08 or 0.3 mcg/kg/day, and increased serum urea nitrogen in dams given calcitriol at a dose of 0.3 mcg/kg/day.

In another study in rats, maternal weight gain was slightly reduced at a dose of 0.3 mcg/kg/day (approximately 3 times the maximum recommended dose based on mg/m 2 ) administered on days 7 to 15 of gestation.

The offspring of a woman administered 17 mcg/day to 36 mcg/day of calcitriol (approximately 17 to 36 times the maximum recommended dose), during pregnancy manifested mild hypercalcemia in the first 2 days of life which returned to normal at day 3.

Nursing Mothers Calcitriol from ingested calcitriol capsules may be excreted in human milk.

Because many drugs are excreted in human milk and because of the potential for serious adverse reactions from calcitriol in nursing infants, a mother should not nurse while taking calcitriol capsules.

NUSRING MOTHERS

Nursing Mothers Calcitriol from ingested calcitriol capsules may be excreted in human milk.

Because many drugs are excreted in human milk and because of the potential for serious adverse reactions from calcitriol in nursing infants, a mother should not nurse while taking calcitriol capsules.

INFORMATION FOR PATIENTS

Information for Patients The patient and his or her caregivers should be informed about compliance with dosage instructions, adherence to instructions about diet and calcium supplementation, and avoidance of the use of unapproved nonprescription drugs.

Patients and their caregivers should also be carefully informed about the symptoms of hypercalcemia (see ADVERSE REACTIONS ).

The effectiveness of calcitriol therapy is predicated on the assumption that each patient is receiving an adequate daily intake of calcium.

Patients are advised to have a dietary intake of calcium at a minimum of 600 mg daily.

The U.S.

RDA for calcium in adults is 800 mg to 1200 mg.

DOSAGE AND ADMINISTRATION

The optimal daily dose of calcitriol must be carefully determined for each patient.

Calcitriol Capsules should be administered orally.

Calcitriol therapy should always be started at the lowest possible dose and should not be increased without careful monitoring of serum calcium.

The effectiveness of calcitriol therapy is predicated on the assumption that each patient is receiving an adequate but not excessive daily intake of calcium.

Patients are advised to have a dietary intake of calcium at a minimum of 600 mg daily.

The U.S.

RDA for calcium in adults is 800 mg to 1200 mg.

To ensure that each patient receives an adequate daily intake of calcium, the physician should either prescribe a calcium supplement or instruct the patient in proper dietary measures.

Because of improved calcium absorption from the gastrointestinal tract, some patients on calcitriol may be maintained on a lower calcium intake.

Patients who tend to develop hypercalcemia may require only low doses of calcium or no supplements at all.

During the titration period of treatment with calcitriol, serum calcium levels should be checked at least twice weekly.

When the optimal dosage of calcitriol has been determined, serum calcium levels should be checked every month (or as given below for individual indications).

Samples for serum calcium estimation should be taken without a tourniquet.

Dialysis Patients The recommended initial dose of calcitriol is 0.25 mcg/day.

If a satisfactory response in the biochemical parameters and clinical manifestations of the disease state is not observed, dosage may be increased by 0.25 mcg/day at 4 to 8 week intervals.

During this titration period, serum calcium levels should be obtained at least twice weekly, and if hypercalcemia is noted, the drug should be immediately discontinued until normocalcemia ensues (see PRECAUTIONS : General ).

Phosphorus, magnesium, and alkaline phosphatase should be determined periodically.

Patients with normal or only slightly reduced serum calcium levels may respond to calcitriol doses of 0.25 mcg every other day.

Most patients undergoing hemodialysis respond to doses between 0.5 and 1 mcg/day.

Oral calcitriol may normalize plasma ionized calcium in some uremic patients, yet fail to suppress parathyroid hyperfunction.

In these individuals with autonomous parathyroid hyperfunction, oral calcitriol may be useful to maintain normocalcemia, but has not been shown to be adequate treatment for hyperparathyroidism.

Hypoparathyroidism The recommended initial dosage of calcitriol is 0.25 mcg/day given in the morning.

If a satisfactory response in the biochemical parameters and clinical manifestations of the disease is not observed, the dose may be increased at 2- to 4-week intervals.

During the dosage titration period, serum calcium levels should be obtained at least twice weekly and, if hypercalcemia is noted, calcitriol should be immediately discontinued until normocalcemia ensues (see PRECAUTIONS : General ).

Careful consideration should also be given to lowering the dietary calcium intake.

Serum calcium, phosphorus, and 24-hour urinary calcium should be determined periodically.

Most adult patients and pediatric patients age 6 years and older have responded to dosages in the range of 0.5 mcg to 2 mcg daily.

Pediatric patients in the 1 to 5 year age group with hypoparathyroidism have usually been given 0.25 mcg to 0.75 mcg daily.

The number of treated patients with pseudohypoparathyroidism less than 6 years of age is too small to make dosage recommendations.

Malabsorption is occasionally noted in patients with hypoparathyroidism; hence, larger doses of calcitriol may be needed.

Predialysis Patients The recommended initial dosage of calcitriol is 0.25 mcg/day in adults and pediatric patients 3 years of age and older.

This dosage may be increased if necessary to 0.5 mcg/day.

For pediatric patients less than 3 years of age, the recommended initial dosage of calcitriol is 10 to 15 ng/kg/day.

levETIRAcetam 500 MG in 5 ML Injection

Generic Name: LEVETIRACETAM
Brand Name: Levetiracetam
  • Substance Name(s):
  • LEVETIRACETAM

OVERDOSAGE

10 10.1 Signs, Symptoms and Laboratory Findings of Acute Overdosage in Humans The highest known dose of oral Levetiracetam received in the clinical development program was 6000 mg/day.

Other than drowsiness, there were no adverse reactions in the few known cases of overdose in clinical trials.

Cases of somnolence, agitation, aggression, depressed level of consciousness, respiratory depression and coma were observed with Levetiracetam overdoses in postmarketing use.

10.2 Management of Overdose There is no specific antidote for overdose with Levetiracetam.

If indicated, elimination of unabsorbed drug should be attempted by emesis or gastric lavage; usual precautions should be observed to maintain airway.

General supportive care of the patient is indicated including monitoring of vital signs and observation of the patient’s clinical status.

A Certified Poison Control Center should be contacted for up to date information on the management of overdose with Levetiracetam.

10.3 Hemodialysis Standard hemodialysis procedures result in significant clearance of levetiracetam (approximately 50% in 4 hours) and should be considered in cases of overdose.

Although hemodialysis has not been performed in the few known cases of overdose, it may be indicated by the patient’s clinical state or in patients with significant renal impairment.

CLINICAL STUDIES

14 All clinical studies supporting the efficacy of Levetiracetam Injection utilized oral formulations.

The finding of efficacy of Levetiracetam Injection is based on the results of studies using an oral formulation of Levetiracetam, and on the demonstration of comparable bioavailability of the oral and parenteral formulations [see Clinical Pharmacology ( 12.3 ) ].

14.1 Partial Onset Seizures Effectiveness in Partial-Onset Seizures in Adults The effectiveness of Levetiracetam for the treatment of partial-onset seizures in adults was established in three multicenter, randomized, double-blind, placebo-controlled clinical studies in patients who had refractory partial onset seizures with or without secondary generalization.

The tablet formulation was used in all these studies.

In these studies, 904 patients were randomized to placebo, 1000 mg, 2000 mg, or 3000 mg/day.

Patients enrolled in Study 1 or Study 2 had refractory partial onset seizures for at least two years and had taken two or more classical AEDs.

Patients enrolled in Study 3 had refractory partial onset seizures for at least 1 year and had taken one classical AED.

At the time of the study, patients were taking a stable dose regimen of at least one and could take a maximum of two AEDs.

During the baseline period, patients had to have experienced at least two partial onset seizures during each 4-week period.

Study 1 Study 1 was a double-blind, placebo-controlled, parallel-group study conducted at 41 sites in the United States comparing Levetiracetam 1000 mg/day (N=97), Levetiracetam 3000 mg/day (N=101), and placebo (N=95) given in equally divided doses twice daily.

After a prospective baseline period of 12 weeks, patients were randomized to one of the three treatment groups described above.

The 18-week treatment period consisted of a 6-week titration period, followed by a 12-week fixed dose evaluation period, during which concomitant AED regimens were held constant.

The primary measure of effectiveness was a between group comparison of the percent reduction in weekly partial seizure frequency relative to placebo over the entire randomized treatment period (titration + evaluation period).

Secondary outcome variables included the responder rate (incidence of patients with ≥50% reduction from baseline in partial onset seizure frequency).

The results of the analysis of Study 1 are displayed in Table 10.

The first period of the study (Period A) was designed to be analyzed as a parallel-group study.

After a prospective baseline period of up to 12 weeks, patients were randomized to one of the three treatment groups described above.

The 16-week treatment period consisted of the 4-week titration period followed by a 12-week fixed dose evaluation period, during which concomitant AED regimens were held constant.

The primary measure of effectiveness was a between group comparison of the percent reduction in weekly partial seizure frequency relative to placebo over the entire randomized treatment period (titration + evaluation period).

Secondary outcome variables included the responder rate (incidence of patients with ≥50% reduction from baseline in partial onset seizure frequency).

The results of the analysis of Period A are displayed in Table 11.

Analysis of the trial as a cross-over yielded similar results.

Study 3 Study 3 was a double-blind, placebo-controlled, parallel-group study conducted at 47 centers in Europe comparing Levetiracetam 3000 mg/day (N=180) and placebo (N=104) in patients with refractory partial onset seizures, with or without secondary generalization, receiving only one concomitant AED.

Study drug was given in two divided doses.

After a prospective baseline period of 12 weeks, patients were randomized to one of two treatment groups described above.

The 16-week treatment period consisted of a 4-week titration period, followed by a 12-week fixed dose evaluation period, during which concomitant AED doses were held constant.

The primary measure of effectiveness was a between group comparison of the percent reduction in weekly seizure frequency relative to placebo over the entire randomized treatment period (titration + evaluation period).

Secondary outcome variables included the responder rate (incidence of patients with ≥50% reduction from baseline in partial onset seizure frequency).

Table 12 displays the results of the analysis of Study 3.

Table 12: Reduction in Mean Over Placebo in Weekly Frequency of Partial-Onset Seizures in Study 3 Placebo (N=104) Levetiracetam 3000 mg/day (N=180) Percent reduction in partial seizure frequency over placebo – 23.0% statistically significant versus placebo The percentage of patients (y-axis) who achieved ≥50% reduction in weekly seizure rates from baseline in partial onset seizure frequency over the entire randomized treatment period (titration + evaluation period) within the two treatment groups (x-axis) is presented in Figure 3.

Figure 3: Responder Rate (≥50% Reduction from Baseline) in Study 3 * statistically significant versus placebo Effectiveness in Partial Onset Seizures in Pediatric Patients 4 Years to 16 Years of Age Study 4 was a multicenter, randomized double-blind, placebo-controlled study, in pediatric patients 4 to 16 years of age with partial seizures uncontrolled by standard antiepileptic drugs (AEDs).

Study 4 was conducted at 60 sites in North America.

The study consisted of an 8-week baseline period and 4-week titration period followed by a 10-week evaluation period.

Eligible patients who still experienced, on a stable dose of 1 to 2 AEDs, at least 4 partial onset seizures during the 4 weeks prior to screening, as well as at least 4 partial onset seizures in each of the two 4-week baseline periods, were randomized to receive either Levetiracetam or placebo.

Dosing was initiated at a dose of 20 mg/kg/day in two divided doses.

During the treatment period, Levetiracetam doses were adjusted in 20 mg/kg/day increments, at 2-week intervals to the target dose of 60 mg/kg/day.

The primary measure of efficacy was a between group comparison of the percent reduction in weekly partial seizure frequency relative to placebo over the entire 14-week randomized treatment period (titration + evaluation period).

Secondary outcome variables included the responder rate (incidence of patients with ≥ 50% reduction from baseline in partial onset seizure frequency per week).

The enrolled population included 198 patients (Levetiracetam N=101, placebo N=97) with refractory partial onset seizures, whether or not secondarily generalized.

Table 13 displays the results of Study 4.

Table 13: Reduction in Mean Over Placebo in Weekly Frequency of Partial-Onset Seizures in Study 4 Placebo (N=97) Levetiracetam (N=101) Percent reduction in partial seizure frequency over placebo – 26.8% statistically significant versus placebo The percentage of patients (y-axis) who achieved ≥ 50% reduction in weekly seizure rates from baseline in partial onset seizure frequency over the entire randomized treatment period (titration + evaluation period) within the two treatment groups (x-axis) is presented in Figure 4.

Figure 4: Responder Rate (≥ 50% Reduction from Baseline) in Study 4 *statistically significant versus placebo Effectiveness in Partial Onset Seizures in Pediatric Patients 1 Month to <4 Years of Age Study 5 was a multicenter, randomized double-blind, placebo-controlled study, in pediatric patients 1 month to less than 4 years of age with partial seizures, uncontrolled by standard epileptic drugs (AEDs).

Study 5 was conducted at 62 sites in North America, South America, and Europe.

Study 5 consisted of a 5-day evaluation period, which included a 1-day titration period followed by a 4-day maintenance period.

Eligible patients who experienced, on a stable dose of 1-2 AEDs, at least 2 partial onset seizures during the 48-hour baseline video EEG were randomized to receive either Levetiracetam or placebo.

Randomization was stratified by age range as follows: 1 month to less than 6 months of age (N=4 treated with Levetiracetam), 6 months to less than 1 year of age (N=8 treated with Levetiracetam), 1 year to less than 2 years of age (N=20 treated with Levetiracetam), and 2 years to less than 4 years of age (N=28 treated with Levetiracetam).

Levetiracetam dosing was determined by age and weight as follows: children 1 month to less than 6 months old were randomized to a target dose of 40 mg/kg/day, and children 6 months to less than 4 years old were randomized to a target dose of 50 mg/kg/day.

The primary measure of efficacy was the responder rate (percent of patients with ≥ 50% reduction from baseline in average daily partial onset seizure frequency) assessed by a blinded central reader using a 48-hour video EEG performed during the last two days of the 4-day maintenance period.

The enrolled population included 116 patients (Levetiracetam N=60, placebo N=56) with refractory partial onset seizures, whether or not secondarily generalized.

A total of 109 patients were included in the efficacy analysis.

A statistically significant difference between Levetiracetam and placebo was observed in Study 5 (see Figure 5).

The treatment effect associated with Levetiracetam was consistent across age groups.

Eligible patients on a stable dose of 1 antiepileptic drug (AED) experiencing one or more myoclonic seizures per day for at least 8 days during the prospective 8-week baseline period were randomized to either Levetiracetam or placebo (Levetiracetam N=60, placebo N=60).

Patients were titrated over 4 weeks to a target dose of 3000 mg/day and treated at a stable dose of 3000 mg/day over 12 weeks (evaluation period).

Study drug was given in 2 divided doses.

The primary measure of efficacy was the proportion of patients with at least 50% reduction in the number of days per week with one or more myoclonic seizures during the treatment period (titration + evaluation periods) as compared to baseline.

Table 14 displays the results for the 113 patients with JME in this study.

Eligible patients on a stable dose of 1 or 2 antiepileptic drugs (AEDs) experiencing at least 3 PGTC seizures during the 8-week combined baseline period (at least one PGTC seizure during the 4 weeks prior to the prospective baseline period and at least one PGTC seizure during the 4-week prospective baseline period) were randomized to either Levetiracetam or placebo.

The 8-week combined baseline period is referred to as “baseline” in the remainder of this section.

Patients were titrated over 4 weeks to a target dose of 3000 mg/day for adults or a pediatric target dose of 60 mg/kg/day and treated at a stable dose of 3000 mg/day (or 60 mg/kg/day for children) over 20 weeks (evaluation period).

Study drug was given in 2 equally divided doses per day.

The primary measure of efficacy was the percent reduction from baseline in weekly PGTC seizure frequency for Levetiracetam and placebo treatment groups over the treatment period (titration + evaluation periods).

The population included 164 patients (Levetiracetam N=80, placebo N=84) with idiopathic generalized epilepsy (predominately juvenile myoclonic epilepsy, juvenile absence epilepsy, childhood absence epilepsy, or epilepsy with Grand Mal seizures on awakening) experiencing primary generalized tonic-clonic seizures.

Each of these syndromes of idiopathic generalized epilepsy was well represented in this patient population.

There was a statistically significant decrease from baseline in PGTC frequency in the Levetiracetam-treated patients compared to the placebo-treated patients in Study 7 (see Table 15).

HOW SUPPLIED

16 /STORAGE AND HANDLING 16.1 How Supplied Levetiracetam Injection 500 mg/5 mL injection is a clear, colorless, sterile solution.

It is supplied in single-dose 5 mL vials, available in cartons of 25 vials (NDC 0143-9574-25).

16.2 Storage Store at 25°C (77°F); excursions permitted to 15 to 30°C (59 to 86°F) [see USP Controlled Room Temperature].

GERIATRIC USE

8.5 Geriatric Use There were 347 subjects in clinical studies of levetiracetam that were 65 years old and over.

No overall differences in safety were observed between these subjects and younger subjects.

There were insufficient numbers of elderly subjects in controlled trials of epilepsy to adequately assess the effectiveness of Levetiracetam Injection in these patients.

Levetiracetam is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function.

Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Clinical Pharmacology ( 12.3 ) ].

DOSAGE FORMS AND STRENGTHS

3 One vial of Levetiracetam Injection contains 500 mg levetiracetam (500 mg/5 mL) as a clear, colorless solution..

Injection: 500 mg/5 mL single dose vial ( 3 )

MECHANISM OF ACTION

12.1 Mechanism of Action The precise mechanism(s) by which levetiracetam exerts its antiepileptic effect is unknown.

A saturable and stereoselective neuronal binding site in rat brain tissue has been described for levetiracetam.

Experimental data indicate that this binding site is the synaptic vesicle protein SV2A, thought to be involved in the regulation of vesicle exocytosis.

Although the molecular significance of levetiracetam binding to synaptic vesicle protein SV2A is not understood, levetiracetam and related analogs showed a rank order of affinity for SV2A which correlated with the potency of their antiseizure activity in audiogenic seizure-prone mice.

These findings suggest that the interaction of levetiracetam with the SV2A protein may contribute to the antiepileptic mechanism of action of the drug.

1.4 Limitations of Use Levetiracetam Injection is for intravenous use only as an alternative for patients when oral administration is temporarily not feasible.

PEDIATRIC USE

8.4 Pediatric Use The safety and effectiveness of Levetiracetam Injection for the treatment of partial onset seizures in patients 1 month to 16 years of age have been established [see Clinical Pharmacology ( 12.3 ) and Clinical Studies ( 14.1 ) ].

The dosing recommendation in these pediatric patients varies according to age group and is weight-based [see Dosage and Administration ( 2.6 ) ].

The safety and effectiveness of Levetiracetam Injection as adjunctive therapy for the treatment of myoclonic seizures in adolescents 12 years of age and older with juvenile myoclonic epilepsy have been established [see Clinical Studies ( 14.2 ) ].

The safety and effectiveness of Levetiracetam Injection as adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in pediatric patients 6 years of age and older with idiopathic generalized epilepsy have been established [see Clinical Studies ( 14.3 ) ].

Safety and effectiveness for the treatment of partial-onset seizures in pediatric patients below the age of 1 month; adjunctive therapy for the treatment of myoclonic seizures in pediatric patients below the age of 12 years; and adjunctive therapy for the treatment of primary generalized tonic-clonic seizures in pediatric patients below the age of 6 years have not been established.

A 3-month, randomized, double-blind, placebo-controlled study was performed to assess the neurocognitive and behavioral effects of Levetiracetam Injection as adjunctive therapy in 98 (Levetiracetam Injection N=64, placebo N=34) pediatric patients, ages 4 years to 16 years, with partial seizures that were inadequately controlled.

The target dose was 60 mg/kg/day.

Neurocognitive effects were measured by the Leiter-R Attention and Memory (AM) Battery, which measures various aspects of a child’s memory and attention.

Although no substantive differences were observed between the placebo and drug treated groups in the median change from baseline in this battery, the study was not adequate to assess formal statistical non-inferiority of the drug and placebo.

The Achenbach Child Behavior Checklist (CBCL/6-18), a standardized validated tool used to assess a child’s competencies and behavioral/emotional problems, was also assessed in this study.

An analysis of the CBCL/6-18 indicated, on average, a worsening in Levetiracetam Injection-treated patients in aggressive behavior, one of the eight syndrome scores [see Warnings and Precautions ( 5.1 ) ].

Juvenile Animal Toxicity Data Studies of levetiracetam in juvenile rats (dosed on postnatal days 4 through 52) and dogs (dosed from postnatal weeks 3 through 7) at doses of up to 1800 mg/kg/day (approximately 7 and 24 times, respectively, the maximum recommended pediatric dose of 60 mg/kg/day on a mg/m 2 basis) did not demonstrate adverse effects on postnatal development.

PREGNANCY

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), including Levetiracetam Injection, during pregnancy.

Encourage women who are taking Levetiracetam Injection during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) pregnancy registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/.

Risk Summary Prolonged experience with Levetiracetam Injection in pregnant women has not identified a drug-associated risk of major birth defects or miscarriage, based on published literature, which includes data from pregnancy registries, and reflects experience over two decades [see Human Data ].

In animal studies, levetiracetam produced developmental toxicity (increased embryofetal and offspring mortality, increased incidences of fetal structural abnormalities, decreased embryofetal and offspring growth, neurobehavioral alterations in offspring) at doses similar to human therapeutic doses [see Animal Data ].

In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

The background risk of major birth defects and miscarriage for the indicated population is unknown.

Clinical Considerations Levetiracetam blood levels may decrease during pregnancy [see Warnings and Precautions ( 5.9 ) ].

Physiological changes during pregnancy may affect levetiracetam concentration.

Decrease in levetiracetam plasma concentrations has been observed during pregnancy.

This decrease is more pronounced during the third trimester.

Dose adjustments may be necessary to maintain clinical response.

Data Human Data While available studies cannot definitively establish the absence of risk, data from the published literature and pregnancy registries have not established an association with levetiracetam use during pregnancy and major birth defects or miscarriage.

Animal Data When levetiracetam (0, 400, 1200, or 3600 mg/kg/day) was administered orally to pregnant rats during the period of organogenesis, reduced fetal weights and increased incidence of fetal skeletal variations were observed at the highest dose tested.

There was no evidence of maternal toxicity.

The no-effect dose for adverse effects on embryofetal developmental in rats (1200 mg/kg/day) is approximately 4 times the maximum recommended human dose (MRHD) of 3000 mg on a body surface area (mg/m 2 ) basis.

Oral administration of levetiracetam (0, 200, 600, or 1800 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in increased embryofetal mortality and incidence of fetal skeletal variations at the mid and high dose and decreased fetal weights and increased incidence of fetal malformations at the high dose, which was associated with maternal toxicity.

The no-effect dose for adverse effects on embryofetal development in rabbits (200 mg/kg/day) is approximately equivalent to the MRHD on a mg/m 2 basis.

Oral administration of levetiracetam (0, 70, 350, or 1800 mg/kg/day) to female rats throughout pregnancy and lactation led to an increased incidence of fetal skeletal variations, reduced fetal body weight, and decreased growth in offspring at the mid and high doses and increased pup mortality and neurobehavioral alterations in offspring at the highest dose tested.

There was no evidence of maternal toxicity.

The no-effect dose for adverse effects on pre-and postnatal development in rats (70 mg/kg/day) is less than the MRHD on a mg/m 2 basis.

Oral administration of levetiracetam to rats during the latter part of gestation and throughout lactation produced no adverse developmental or maternal effects at doses of up to 1800 mg/kg/day (6 times the MRHD on a mg/m 2 basis).

WARNING AND CAUTIONS

5 WARNINGS AND PRECAUTIONS Behavioral abnormalities including psychotic symptoms, suicidal ideation, irritability, and aggressive behavior have been observed; monitor patients for psychiatric signs and symptoms ( 5.1 ) Monitor for somnolence and fatigue; advise patients not to drive or operate machinery until they have sufficient experience on Levetiracetam Injection ( 5.2 ) Serious Dermatological Reactions: Discontinue Levetiracetam Injection at the first sign of rash unless clearly not drug related ( 5.4 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity: Discontinue if no alternative etiology ( 5.5 ) Coordination Difficulties: Monitor for ataxia, abnormal gait, and incoordination ( 5.6 ) Withdrawal Seizures: Levetiracetam Injection must be gradually withdrawn.

( 5.7 ) 5.1 Behavioral Abnormalities and Psychotic Symptoms Levetiracetam Injection may cause behavioral abnormalities and psychotic symptoms.

Patients treated with Levetiracetam Injection should be monitored for psychiatric signs and symptoms.

Behavioral abnormalities In clinical studies using an oral formulation of Levetiracetam, 13% of adult Levetiracetam-treated patients and 38% of pediatric Levetiracetam-treated patients (4 to 16 years of age), compared to 6% and 19% of adult and pediatric placebo-treated patients, experienced nonpsychotic behavioral symptoms (reported as aggression, agitation, anger, anxiety, apathy, depersonalization, depression, emotional lability, hostility, hyperkinesias, irritability, nervousness, neurosis, and personality disorder).

A randomized, double-blind, placebo-controlled study was performed to assess the neurocognitive and behavioral effects of an oral formulation of Levetiracetam as adjunctive therapy in pediatric patients (4 to 16 years of age).

The results from an exploratory analysis indicated a worsening in Levetiracetam-treated patients on aggressive behavior (one of eight behavior dimensions), as measured in a standardized and systematic way using a validated instrument, the Achenbach Child Behavior Checklist (CBCL/6-18).

In clinical studies in pediatric patients 1 month to < 4 years of age, irritability was reported in 12% of the Levetiracetam-treated patients compared to 0% of placebo-treated patients.

In clinical studies, 1.7% of adult Levetiracetam-treated patients discontinued treatment due to behavioral adverse reactions, compared to 0.2% of placebo-treated patients.

The treatment dose was reduced in 0.8% of adult Levetiracetam-treated patients and in 0.5% of placebo-treated patients.

Overall, 11% of Levetiracetam-treated pediatric patients experienced behavioral symptoms associated with discontinuation or dose reduction, compared to 6% of placebo-treated patients.

Psychotic symptoms In clinical studies using an oral formulation of Levetiracetam, 1% of Levetiracetam-treated adult patients, 2% of Levetiracetam-treated pediatric patients 4 to 16 years of age, and 17% of levetiracetam-treated pediatric patients 1 month to <4 years of age experienced psychotic symptoms, compared to 0.2%, 2%, and 5% in the corresponding age groups treated with placebo.

In a controlled study that assessed the neurocognitive and behavioral effects of an oral formulation of Levetiracetam in pediatric patients 4 to 16 years of age, 1.6% of Levetiracetam-treated patients experienced paranoia, compared to 0% of placebo-treated patients.

In the same study, 3.1% of Levetiracetam-treated patients experienced confusional state, compared to 0% of placebo-treated patients [see Use in Specific Populations ( 8.4 ) ].

In clinical studies, two (0.3%) Levetiracetam-treated adult patients were hospitalized, and their treatment was discontinued due to psychosis.

Both events, reported as psychosis, developed within the first week of treatment and resolved within 1 to 2 weeks following treatment discontinuation.

There was no difference between drug- and placebo-treated patients in the incidence of the pediatric patients who discontinued treatment due to psychotic and non-psychotic adverse reactions.

5.2 Somnolence and Fatigue Levetiracetam Injection may cause somnolence and fatigue.

Patients should be monitored for somnolence and fatigue, and be advised not to drive or operate machinery until they have gained sufficient experience on Levetiracetam Injection to gauge whether it adversely affects their ability to drive or operate machinery.

Somnolence In controlled clinical studies using an oral formulation of Levetiracetam in adult patients with partial-onset seizures, 15% of Levetiracetam-treated patients reported somnolence, compared to 8% of placebo-treated patients.

There was no clear dose response up to 3000 mg/day.

In a study in which there was no titration, about 45% of patients receiving levetiracetam 4000 mg/day reported somnolence.

The somnolence was considered serious in 0.3% of Levetiracetam-treated patients, compared to 0% in the placebo group.

About 3% of Levetiracetam-treated patients discontinued treatment due to somnolence, compared to 0.7% of placebo-treated patients.

In 1.4% of Levetiracetam-treated patients and 0.9% of placebo-treated patients, the dose was reduced, while 0.3% of the Levetiracetam-treated patients were hospitalized due to somnolence.

Asthenia In controlled clinical studies using an oral formulation of levetiracetam in adult patients with partial onset seizures, 15% of Levetiracetam-treated patients reported asthenia, compared to 9% of placebo-treated patients.

Treatment was discontinued due to asthenia in 0.8% of Levetiracetam-treated patients as compared to 0.5% of placebo-treated patients.

In 0.5% of Levetiracetam-treated patients and in 0.2% of placebo-treated patients, the dose was reduced due to asthenia.

Somnolence and asthenia occurred most frequently within the first 4 weeks of treatment.

In general, the incidences of somnolence and fatigue in the pediatric partial onset seizure studies, and in pediatric and adult myoclonic and primary generalized tonic-clonic studies were comparable to those of the adult partial-onset seizure studies.

5.3 Anaphylaxis and Angioedema Levetiracetam Injection can cause anaphylaxis or angioedema after the first dose or at any time during treatment.

Signs and symptoms in cases reported in the postmarketing setting have included hypotension, hives, rash, respiratory distress, and swelling of the face, lip, mouth, eye, tongue, throat, and feet.

In some reported cases, reactions were life-threatening and required emergency treatment.

If a patient develops signs or symptoms of anaphylaxis or angioedema, Levetiracetam Injection should be discontinued and the patient should seek immediate medical attention.

Levetiracetam Injection should be discontinued permanently if a clear alternative etiology for the reaction cannot be established [see Contraindications (4) ].

5.4 Serious Dermatological Reactions Serious dermatological reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), have been reported in both pediatric and adult patients treated with Levetiracetam Injection.

The median time of onset is reported to be 14 to 17 days, but cases have been reported at least four months after initiation of treatment.

Recurrence of the serious skin reactions following rechallenge with Levetiracetam Injection has also been reported.

Levetiracetam Injection should be discontinued at the first sign of a rash, unless the rash is clearly not drug-related.

If signs or symptoms suggest SJS/TEN, use of this drug should not be resumed and alternative therapy should be considered.

5.5 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including Levetiracetam Injection.

These events can be fatal or life- threatening, particularly if diagnosis and treatment do not occur as early as possible.

Levetiracetam Injection typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling, in association with other organ system involvement, such as hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis, sometimes resembling an acute viral infection.

Eosinophilia is often present.

Because this disorder is variable in its expression, other organ systems not noted here may be involved.

It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident.

If such signs or symptoms are present, the patient should be evaluated immediately.

Levetiracetam Injection should be discontinued if an alternative etiology for the signs or symptoms cannot be established [see Contraindications (4) ].

5.6 Coordination Difficulties Levetiracetam Injection may cause coordination difficulties.

In controlled clinical studies using an oral formulation of Levetiracetam in adult patients with partial-onset seizures, 3.4% of Levetiracetam-treated patients experienced coordination difficulties, (reported as ataxia, abnormal gait, or incoordination) compared to 1.6% of placebo-treated patients.

A total of 0.4% of patients in controlled clinical studies discontinued Levetiracetam treatment due to ataxia, compared to 0% of placebo-treated patients.

In 0.7% of Levetiracetam-treated patients and in 0.2% of placebo-treated patients, the dose was reduced due to coordination difficulties, while one of the treated patients was hospitalized due to worsening of pre-existing ataxia.

These events occurred most frequently within the first 4 weeks of treatment.

Patients should be monitored for signs and symptoms of coordination difficulties and advised not to drive or operate machinery until they have gained sufficient experience on Levetiracetam Injection to gauge whether it could adversely affect their ability to drive or operate machinery.

5.7 Withdrawal Seizures As with most antiepileptic drugs, Levetiracetam Injection should generally be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus.

But if withdrawal is needed because of a serious adverse reaction, rapid discontinuation can be considered.

5.8 Hematologic Abnormalities Levetiracetam Injection can cause hematologic abnormalities.

Hematologic abnormalities occurred in clinical trials and included decreases in white blood cell (WBC), neutrophil, and red blood cells counts (RBC); decreases in hemoglobin and hematocrit; and increases in eosinophil counts.

Cases of agranulocytosis, pancytopenia, and thrombocytopenia have been reported in the postmarketing setting.

A complete blood count is recommended in patients experiencing significant weakness, pyrexia, recurrent infections, or coagulation disorders.

Partial-Onset Seizures Adults In controlled clinical studies using an oral formulation of Levetiracetam in adult patients with partial-onset seizures, minor but statistically significant decreases compared to placebo in total mean RBC (0.03 x 10 6 /mm 3 ), mean hemoglobin (0.09 g/dL), and mean hematocrit (0.38%), were seen in Levetiracetam-treated patients.

A total of 3.2% of Levetiracetam-treated and 1.8% of placebo-treated patients had at least one possibly significant (≤2.8 x 10 9 /L) decreased WBC, and 2.4% of Levetiracetam-treated and 1.4% of placebo-treated patients had at least one possibly significant (≤1.0 x 10 9 /L) decreased neutrophil count.

Of the Levetiracetam-treated patients with a low neutrophil count, all but one rose towards or to baseline with continued treatment.

No patient was discontinued secondary to low neutrophil counts.

Pediatric Patients 4 Years to < 16 Years In a controlled study in pediatric patients age 4 years to <16 years, statistically significant decreases in WBC and neutrophil counts were seen in Levetiracetam-treated patients, as compared to placebo.

The mean decreases from baseline in the Levetiracetam-treated group were -0.4 × 10 9 /L and -0.3 × 10 9 /L, respectively, whereas there were small increases in the placebo group.

Mean relative lymphocyte counts increased by 1.7% in Levetiracetam-treated patients, compared to a decrease of 4% in placebo-treated patients (statistically significant).

More Levetiracetam-treated patients had a possibly clinically significant abnormally low WBC value (3% of Levetiracetam-treated patients versus 0% of placebo-treated patients); however, there was no apparent difference between treatment groups with respect to neutrophil count (5% on Levetiracetam versus 4.2% on placebo).

No patient was discontinued because of low WBC or neutrophil count.

In a randomized, double-blind, placebo-controlled study to assess the neurocognitive and behavioral effects of an oral formulation of Levetiracetam as adjunctive therapy in pediatric patients (4 to 16 years of age), 5 patients (8.6%) in the Levetiracetam-treated group and two patients (6.1%) in the placebo-treated group had high eosinophil count values that were possibly clinically significant (≥10% or ≥0.7X10 9 /L).

5.9 Increase in Blood Pressure In a randomized, placebo-controlled study in patients 1 month to <4 years of age using an oral formulation of Levetiracetam, a significantly higher risk of increased diastolic blood pressure was observed in the Levetiracetam-treated patients (17%), compared to placebo-treated patients (2%).

There was no overall difference in mean diastolic blood pressure between the treatment groups.

This disparity between the Levetiracetam and placebo treatment groups was not observed in the studies of older children or in adults.

Monitor patients 1 month to <4 years of age for increases in diastolic blood pressure.

5.10 Seizure Control During Pregnancy Physiological changes may gradually decrease plasma levels of levetiracetam throughout pregnancy.

This decrease is more pronounced during the third trimester.

It is recommended that patients be monitored carefully during pregnancy.

Close monitoring should continue through the postpartum period especially if the dose was changed during pregnancy.

Increase the daily dose every 2 weeks by increments of 20 mg/kg (10 mg/kg twice daily) to the recommended daily dose of 60 mg/kg (30 mg/kg twice daily).

The effectiveness of doses lower than 60 mg/kg/day has not been adequately studied.

2.4 Switching from Oral Dosing When switching from oral Levetiracetam, the initial total daily intravenous dosage of Levetiracetam Injection should be equivalent to the total daily dosage and frequency of oral Levetiracetam.

2.5 Switching to Oral Dosing At the end of the intravenous treatment period, the patient may be switched to Levetiracetam oral administration at the equivalent daily dosage and frequency of the intravenous administration.

2.6 Preparation and Administration Instructions Levetiracetam Injection is for intravenous use only and should be diluted in 100 mL of a compatible diluent prior to administration.

If a smaller volume is required (e.g., pediatric patients), the amount of diluent should be calculated to not exceed a maximum levetiracetam concentration of 15 mg per mL of diluted solution.

Consideration should also be given to the total daily fluid intake of the patient.

Levetiracetam Injection should be administered as a 15-minute IV infusion.

One vial of Levetiracetam Injection contains 500 mg levetiracetam (500 mg/5 mL).

Levetiracetam Injection may be mixed with the following diluents and antiepileptic drugs and may be stored in polyvinyl chloride (PVC) bags.

The diluted solution should not be stored for more than 4 hours at controlled room temperature [15-30⁰C (59-86⁰F)].

Diluents: Sodium chloride (0.9%) injection, USP Lactated Ringer’s injection Dextrose 5% injection, USP Other Antiepileptic Drugs: Lorazepam Diazepam Valproate sodium There are no data to support the physical compatibility of Levetiracetam Injection with antiepileptic drugs that are not listed above.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

Product with particulate matter or discoloration should not be used.

Any unused portion of the Levetiracetam Injection vial contents should be discarded.

Adults See Table 1 for the recommended preparation and administration of Levetiracetam Injection for adults to achieve a dose of 500 mg, 1000 mg, or 1500 mg.

Table 1: Preparation and Administration of Levetiracetam Injection for Adults Dose Withdraw Volume Volume of Diluent Infusion Time 500 mg 5 mL (5 mL vial) 100 mL 15 minutes 1000 mg 10 mL (two 5 mL vials) 100 mL 15 minutes 1500 mg 15 mL (three 5 mL vials) 100 mL 15 minutes For example, to prepare a 1000 mg dose, dilute 10 mL of Levetiracetam Injection in 100 mL of a compatible diluent and administer intravenously as a 15-minute infusion.

Pediatric Patients When using Levetiracetam Injection for pediatric patients, dosing is weight-based (mg per kg).

The following calculation should be used to determine the appropriate daily dose of Levetiracetam Injection for pediatric patients: Total daily dose (mL/day) = Daily dose (mg/kg/day) x patient weight (kg) 100 mg/mL 2.7 Dosage Adjustments in Adult Patients with Renal Impairment Levetiracetam Injection dosing must be individualized according to the patient’s renal function status.

Recommended dosage adjustments for adults with renal impairment are shown in Table 2.

Information is unavailable for dosage adjustments in pediatric patients with renal impairment.

In order to calculate the dose recommended for adult patients with renal impairment, creatinine clearance adjusted for body surface area must be calculated.

To do this an estimate of the patient’s creatinine clearance (CLcr) in mL/min must first be calculated using the following formula: CLcr = [140-age (years)] x weight (kg) (x 0.85 for female patients) 72 x serum creatinine (mg/dL) Then CLcr is adjusted for body surface area (BSA) as follows: CLcr (mL/min/1.73m 2 ) = CLcr (mL/min) x 1.73 BSA subject (m 2 ) Table 2: Dosage Adjustment Regimen for Adult Patients with Renal Impairment Group Creatinine Clearance (mL/min/1.73 m 2 ) Dosage (mg) Frequency Normal > 80 500 to 1,500 Every 12 hours Mild 50 – 80 500 to 1,000 Every 12 hours Moderate 30 – 50 250 to 750 Every 12 hours Severe < 30 250 to 500 Every 12 hours ESRD patients using dialysis —– 500 to 1,0001 Following dialysis, a 250 to 500 mg supplemental dose is recommended.

Every 24 hours 2.8 Discontinuation of Levetiracetam Injection Avoid abrupt withdrawal from Levetiracetam Injection in order to reduce the risk of increased seizure frequency and status epilepticus [see Warnings and Precautions ( 5.6 ) ].

amikacin sulfate 500 MG in 2 ML Injection

Generic Name: AMIKACIN SULFATE
Brand Name: Amikacin Sulfate
  • Substance Name(s):
  • AMIKACIN SULFATE

WARNINGS

See box above.

Aminoglycosides can cause fetal harm when administered to a pregnant woman.

Aminoglycosides cross the placenta and there have been several reports of total irreversible, bilateral congenital deafness in children whose mothers received streptomycin during pregnancy.

Although serious side effects to the fetus or newborns have not been reported in the treatment of pregnant women with other aminoglycosides, the potential for harm exists.

Reproduction studies of amikacin have been performed in rats and mice and revealed no evidence of impaired fertility or harm to the fetus due to amikacin.

There are no well controlled studies in pregnant women, but investigational experience does not include any positive evidence of adverse effects to the fetus.

If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.

Contains sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people.

The overall prevalence of sulfite sensitivity in the general population is unknown and probably low.

Sulfite sensitivity is seen more frequently in asthmatic than nonasthmatic people.

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Amikacin Sulfate Injection, and may range in severity from mild diarrhea to fatal colitis.

Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C.

difficile .

C.

difficile produces toxins A and B which contribute to the development of CDAD.

Hypertoxin producing strains of C.

difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy.

CDAD must be considered in all patients who present with diarrhea following antibiotic use.

Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.

If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C.

difficile may need to be discontinued.

Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C.

difficile , and surgical evaluation should be instituted as clinically indicated.

Risk of Ototoxicity Due to Mitochondrial DNA Variants Cases of ototoxicity with aminoglycosides have been observed in patients with certain variants in the mitochondrially encoded 12S rRNA gene (MT-RNR1), particularly the m.1555A>G variant.

Ototoxicity occurred in some patients even when their aminoglycoside serum levels were within the recommended range.

Mitochondrial DNA variants are present in less than 1 % of the general US population, and the proportion of the variant carriers who may develop ototoxicity as well as the severity of ototoxicity is unknown.

In case of known maternal history of ototoxicity due to aminoglycoside use or a known mitochondrial DNA variant in the patient, consider alternative treatments other than aminoglycosides unless the increased risk of permanent hearing loss is outweighed by the severity of infection and lack of safe and effective alternative therapies.

OVERDOSAGE

In the event of overdosage or toxic reaction, peritoneal dialysis or hemodialysis will aid in the removal of amikacin from the blood.

In the newborn infant, exchange transfusion may also be considered.

MECHANISM OF ACTION

Mechanism of Action Amikacin, an aminoglycoside, binds to the prokaryotic ribosome, inhibiting protein synthesis in susceptible bacteria.

It is bactericidal in vitro against Gram-positive and Gram-negative bacteria.

INDICATIONS AND USAGE

Amikacin Sulfate Injection is indicated in the short-term treatment of serious infections due to susceptible strains of Gram-negative bacteria, including Pseudomonas species, Escherichia coli , species of indole-positive and indole-negative Proteus , Providencia species, Klebsiella-Enterobacter-Serratia species, and Acinetobacter ( Mima-Herellea ) species.

Clinical studies have shown Amikacin Sulfate Injection to be effective in bacterial septicemia (including neonatal sepsis); in serious infections of the respiratory tract, bones and joints, central nervous system (including meningitis) and skin and soft tissue; intra-abdominal infections (including peritonitis); and in burns and post-operative infections (including post-vascular surgery).

Clinical studies have shown amikacin also to be effective in serious complicated and recurrent urinary tract infections due to these organisms.

Aminoglycosides, including Amikacin Sulfate Injection are not indicated in uncomplicated initial episodes of urinary tract infections unless the causative organisms are not susceptible to antibiotics having less potential toxicity.

Bacteriologic studies should be performed to identify causative organisms and their susceptibilities to amikacin.

Amikacin may be considered as initial therapy in suspected Gram-negative infections and therapy may be instituted before obtaining the results of susceptibility testing.

Clinical trials demonstrated that amikacin was effective in infections caused by gentamicin- and/or tobramycin-resistant strains of Gram-negative organisms, particularly Proteus rettgeri , Providencia stuartii , Serratia marcescens , and Pseudomonas aeruginosa .

The decision to continue therapy with the drug should be based on results of the susceptibility tests, the severity of the infection, the response of the patient and the important additional considerations contained in the WARNINGS box above.

Amikacin has also been shown to be effective in staphylococcal infections and may be considered as initial therapy under certain conditions in the treatment of known or suspected staphylococcal disease such as, severe infections where the causative organism may be either a Gram-negative bacterium or a staphylococcus, infections due to susceptible strains of staphylococci in patients allergic to other antibiotics, and in mixed staphylococci/Gram-negative infections.

In certain severe infections such as neonatal sepsis, concomitant therapy with a penicillin-type drug may be indicated because of the possibility of infections due to Gram-positive organisms such as streptococci or pneumococci.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of amikacin and other antibacterial drugs, amikacin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy.

In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

PEDIATRIC USE

Pediatric Use Aminoglycosides should be used with caution in premature and neonatal infants because of the renal immaturity of these patients and the resulting prolongation of serum half-life of these drugs.

PREGNANCY

Pregnancy Teratogenic Effects; Pregnancy (See WARNINGS section.)

NUSRING MOTHERS

Nursing Mothers It is not known whether amikacin is excreted in human milk.

Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from amikacin, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

BOXED WARNING

WARNINGS Patients treated with parenteral aminoglycosides should be under close clinical observation because of the potential ototoxicity and nephrotoxicity associated with their use.

Safety for treatment periods which are longer than 14 days has not been established.

Neurotoxicity, manifested as vestibular and permanent bilateral auditory ototoxicity, can occur in patients with preexisting renal damage and in patients with normal renal function treated at higher doses and/or for periods longer than those recommended.

The risk of aminoglycoside-induced ototoxicity is greater in patients with renal damage.

High frequency deafness usually occurs first and can be detected only by audiometric testing.

Vertigo may occur and may be evidence of vestibular injury.

Other manifestations of neurotoxicity may include numbness, skin tingling, muscle twitching and convulsions.

The risk of hearing loss due to aminoglycosides increases with the degree of exposure to either high peak or high trough serum concentrations.

Patients developing cochlear damage may not have symptoms during therapy to warn them of developing eighth-nerve toxicity, and total or partial irreversible bilateral deafness may occur after the drug has been discontinued.

Aminoglycoside-induced ototoxicity is usually irreversible.

Aminoglycosides are potentially nephrotoxic.

The risk of nephrotoxicity is greater in patients with impaired renal function and in those who receive high doses or prolonged therapy.

Neuromuscular blockade and respiratory paralysis have been reported following parenteral injection, topical instillation (as in orthopedic and abdominal irrigation or in local treatment of empyema), and following oral use of aminoglycosides.

The possibility of these phenomena should be considered if aminoglycosides are administered by any route, especially in patients receiving anesthetics, neuromuscular blocking agents such as tubocurarine, succinylcholine, decamethonium, or in patients receiving massive transfusions of citrate-anticoagulated blood.

If blockage occurs, calcium salts may reverse these phenomena, but mechanical respiratory assistance may be necessary.

Renal and eighth-nerve function should be closely monitored especially in patients with known or suspected renal impairment at the onset of therapy and also in those whose renal function is initially normal but who develop signs of renal dysfunction during therapy.

Serum concentrations of amikacin should be monitored when feasible to assure adequate levels and to avoid potentially toxic levels and prolonged peak concentrations above 35 micrograms per mL.

Urine should be examined for decreased specific gravity, increased excretion of proteins, and the presence of cells or casts.

Blood urea nitrogen, serum creatinine, or creatinine clearance should be measured periodically.

Serial audiograms should be obtained where feasible in patients old enough to be tested, particularly high risk patients.

Evidence of ototoxicity (dizziness, vertigo, tinnitus, roaring in the ears, and hearing loss) or nephrotoxicity requires discontinuation of the drug or dosage adjustment.

Concurrent and/or sequential systemic, oral or topical use of other neurotoxic or nephrotoxic products, particularly bacitracin, cisplatin, amphotericin B, cephaloridine, paromomycin, viomycin, polymyxin B, colistin, vancomycin, or other aminoglycosides should be avoided.

Other factors that may increase risk of toxicity are advanced age and dehydration.

The concurrent use of amikacin with potent diuretics (ethacrynic acid, or furosemide) should be avoided since diuretics by themselves may cause ototoxicity.

In addition, when administered intravenously, diuretics may enhance aminoglycoside toxicity by altering antibiotic concentrations in serum and tissue.

INFORMATION FOR PATIENTS

Information for Patients Patients should be counseled that antibacterial drugs including amikacin should only be used to treat bacterial infections.

They do not treat viral infections (e.g., the common cold).

When amikacin is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed.

Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by amikacin or other antibacterial drugs in the future.

Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued.

Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic.

If this occurs, patients should contact their physician as soon as possible.

DOSAGE AND ADMINISTRATION

The patient’s pretreatment body weight should be obtained for calculation of correct dosage.

Amikacin Sulfate Injection may be given intramuscularly or intravenously.

The status of renal function should be estimated by measurement of the serum creatinine concentration or calculation of the endogenous creatinine clearance rate.

The blood urea nitrogen (BUN) is much less reliable for this purpose.

Reassessment of renal function should be made periodically during therapy.

Whenever possible, amikacin concentrations in serum should be measured to assure adequate but not excessive levels.

It is desirable to measure both peak and trough serum concentrations intermittently during therapy.

Peak concentrations (30 to 90 minutes after injection) above 35 micrograms per mL and trough concentrations (just prior to the next dose) above 10 micrograms per mL should be avoided.

Dosage should be adjusted as indicated.

Intramuscular Administration for Patients with Normal Renal Function The recommended dosage for adults, children and older infants (see WARNINGS box) with normal renal function is 15 mg/kg/day divided into 2 or 3 equal doses administered at equally-divided intervals, i.e., 7.5 mg/kg q12h or 5 mg/kg q8h.

Treatment of patients in the heavier weight classes should not exceed 1.5 gram/day.

When amikacin is indicated in newborns (see WARNINGS box), it is recommended that a loading dose of 10 mg/kg be administered initially to be followed with 7.5 mg/kg every 12 hours.

The usual duration of treatment is 7 to 10 days.

It is desirable to limit the duration of treatment to short term whenever feasible.

The total daily dose by all routes of administration should not exceed 15 mg/kg/day.

In difficult and complicated infections where treatment beyond 10 days is considered, the use of amikacin should be reevaluated.

If continued, amikacin serum levels, and renal, auditory, and vestibular functions should be monitored.

At the recommended dosage level, uncomplicated infections due to amikacin-sensitive organisms should respond in 24 to 48 hours.

If definite clinical response does not occur within 3 to 5 days, therapy should be stopped and the antibiotic susceptibility pattern of the invading organism should be rechecked.

Failure of the infection to respond may be due to resistance of the organism or to the presence of septic foci requiring surgical drainage.

When amikacin is indicated in uncomplicated urinary tract infections, a dose of 250 mg twice daily may be used.

DOSAGE GUIDELINES ADULTS AND CHILDREN WITH NORMAL RENAL FUNCTION Patient Weight Dosage lbs kg 7.5 mg/kg q12h OR 5 mg/kg q8h 99 45 337.5 mg 225 mg 110 50 375 mg 250 mg 121 55 412.5 mg 275 mg 132 60 450 mg 300 mg 143 65 487.5 mg 325 mg 154 70 525 mg 350 mg 165 75 562.5 mg 375 mg 176 80 600 mg 400 mg 187 85 637.5 mg 425 mg 198 90 675 mg 450 mg 209 95 712.5 mg 475 mg 220 100 750 mg 500 mg Intramuscular Administration for Patients with Impaired Renal Function Whenever possible, serum amikacin concentrations should be monitored by appropriate assay procedures.

Doses may be adjusted in patients with impaired renal function either by administering normal doses at prolonged intervals or by administering reduced doses at a fixed interval.

Both methods are based on the patient’s creatinine clearance or serum creatinine values since these have been found to correlate with aminoglycoside half-lives in patients with diminished renal function.

These dosage schedules must be used in conjunction with careful clinical and laboratory observations of the patient and should be modified as necessary.

Neither method should be used when dialysis is being performed.

Normal Dosage at Prolonged Intervals If the creatinine clearance rate is not available and the patient’s condition is stable, a dosage interval in hours for the normal dose can be calculated by multiplying the patient’s serum creatinine by 9, e.g., if the serum creatinine concentration is 2 mg/100 mL, the recommended single dose (7.5 mg/kg) should be administered every 18 hours.

Reduced Dosage at Fixed Time Intervals When renal function is impaired and it is desirable to administer amikacin at a fixed time interval, dosage must be reduced.

In these patients, serum amikacin concentrations should be measured to assure accurate administration of amikacin and to avoid concentrations above 35 mcg/mL.

If serum assay determinations are not available and the patient’s condition is stable, serum creatinine and creatinine clearance values are the most readily available indicators of the degree of renal impairment to use as a guide for dosage.

First, initiate therapy by administering a normal dose, 7.5 mg/kg, as a loading dose.

This loading dose is the same as the normally recommended dose which would be calculated for a patient with a normal renal function as described above.

To determine the size of maintenance doses administered every 12 hours, the loading dose should be reduced in proportion to the reduction in the patient’s creatinine clearance rate: Maintenance Dose Every 12 hours = observed CC in mL/min X Calculated loading dose in mg normal CC in mL/min (CC – creatinine clearance rate) An alternate rough guide for determining reduced dosage at 12-hour intervals (for patients whose steady state serum creatinine values are known) is to divide the normally recommended dose by the patient’s serum creatinine.

The above dosage schedules are not intended to be rigid recommendations but are provided as guides to dosage when the measurement of amikacin serum levels is not feasible.

Intravenous Administration The individual dose, the total daily dose, and the total cumulative dose of amikacin sulfate are identical to the dose recommended for intramuscular administration.

The solution for intravenous use is prepared by adding the contents of a 500 mg vial to 100 or 200 mL of sterile diluent such as 0.9% sodium chloride injection or 5% dextrose injection or any of the compatible solutions listed below.

The solution is administered to adults over a 30 to 60 minute period.

The total daily dose should not exceed 15 mg/kg/day and may be divided into either 2 or 3 equally-divided doses at equally-divided intervals.

In pediatric patients the amount of fluid used will depend on the amount of amikacin ordered for the patient.

It should be a sufficient amount to infuse the Amikacin Sulfate Injection over a 30 to 60 minute period.

Infants should receive a 1 to 2 hour infusion.

Amikacin should not be physically premixed with other drugs but should be administered separately according to the recommended dose and route.

Stability in IV Fluids Amikacin sulfate is stable for 24 hours at room temperature at concentrations of 0.25 and 5 mg/mL in the following solutions: 5% Dextrose Injection 5% Dextrose and 0.2% Sodium Chloride Injection 5% Dextrose and 0.45% Sodium Chloride Injection 0.9% Sodium Chloride Injection Lactated Ringer’s Injection Normosol ® M in 5% Dextrose Injection (or Plasma-Lyte 56 Injection in 5% Dextrose in Water) Normosol ® R in 5% Dextrose Injection (or Plasma-Lyte 148 Injection in 5% Dextrose in Water) In the above solutions with Amikacin Sulfate Injection concentrations of 0.25 and 5 mg/mL, solutions aged for 60 days at 4°C and then stored at 25°C had utility times of 24 hours.

At the same concentrations, solutions frozen and aged for 30 days at -15°C, thawed, and stored at 25°C had utility times of 24 hours.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

Aminoglycosides administered by any of the above routes should not be physically premixed with other drugs but should be administered separately.

Because of the potential toxicity of aminoglycosides, “fixed dosage” recommendations which are not based upon body weight are not advised.

Rather, it is essential to calculate the dosage to fit the needs of each patient.

WARNINGS

Clinical Worsening and Suicide Risk Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs.

Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide.

There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment.

Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18–24) with major depressive disorder (MDD) and other psychiatric disorders.

Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older.

The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 antidepressant drugs in over 4400 patients.

The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients.

There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied.

There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD.

The risk differences (drug vs.

placebo), however, were relatively stable within age strata and across indications.

These risk differences (drug-placebo difference in the number of cases of suicidality per 1000 patients treated) are provided in Table 1.

Table 1 Age Range Drug-Placebo Difference in Number of Cases of Suicidality per 1000 Patients Treated Increases Compared to Placebo <18 14 additional cases 18–24 5 additional cases Decreases Compared to Placebo 25–64 1 fewer case ≥65 6 fewer cases No suicides occurred in any of the pediatric trials.

There were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide.

It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months.

However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression.

All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases.

The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric.

Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality.

Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient’s presenting symptoms.

If the decision has been made to discontinue treatment, medication should be tapered, as rapidly as is feasible, but with recognition that abrupt discontinuation can be associated with certain symptoms (see PRECAUTIONS and DOSAGE AND ADMINISTRATION—Discontinuation of Treatment with ZOLOFT, for a description of the risks of discontinuation of ZOLOFT).

Families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to health care providers.

Such monitoring should include daily observation by families and caregivers.

Prescriptions for ZOLOFT should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose.

Screening Patients for Bipolar Disorder A major depressive episode may be the initial presentation of bipolar disorder.

It is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder.

Whether any of the symptoms described above represent such a conversion is unknown.

However, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression.

It should be noted that ZOLOFT is not approved for use in treating bipolar depression.

Cases of serious sometimes fatal reactions have been reported in patients receiving ZOLOFT (sertraline hydrochloride), a selective serotonin reuptake inhibitor (SSRI), in combination with a monoamine oxidase inhibitor (MAOI).

Symptoms of a drug interaction between an SSRI and an MAOI include: hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, mental status changes that include confusion, irritability, and extreme agitation progressing to delirium and coma.

These reactions have also been reported in patients who have recently discontinued an SSRI and have been started on an MAOI.

Some cases presented with features resembling neuroleptic malignant syndrome.

Therefore, ZOLOFT should not be used in combination with an MAOI, or within 14 days of discontinuing treatment with an MAOI.

Similarly, at least 14 days should be allowed after stopping ZOLOFT before starting an MAOI.

The concomitant use of Zoloft with MAOIs intended to treat depression is contraindicated (see CONTRAINDICATIONS and – Potential for Interaction with Monoamine Oxidase Inhibitors ).

Serotonin Syndrome The development of a potentially life-threatening serotonin syndrome may occur in treatment with SNRIs and SSRIs, including Zoloft, particularly with concomitant use of serotonergic drugs (including triptans) and with drugs which impair metabolism of serotonin (including MAOIs).

Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination) and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

If concomitant treatment of SNRIs and SSRIs, including Zoloft, with a 5-hydroxytryptamine receptor agonist (triptan) is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases (see PRECAUTIONS – Drug Interactions ).

The concomitant use of SNRIs and SSRIs, including Zoloft, with serotonin precursors (such as tryptophan) is not recommended (see PRECAUTIONS – Drug Interactions ).

Neuroleptic Malignant Syndrome (NMS) or NMS-Like Reactions Rare instances of neuroleptic malignant syndrome (NMS) or NMS-like reactions have been reported when a selective serotonin reuptake inhibitor (SSRI) drug, such as sertraline, or a serotonin-norepinephrine reuptake inhibitor (SNRI) was added to antipsychotic drug therapy.

Additionally, a small number of such cases have been reported with SSRI’s and SNRI’s in the absence of antipsychotic coadministration.

These serious and sometimes fatal events can include hyperthermia, muscle rigidity, autonomic instability with possible rapid fluctuation of vital signs, and mental status changes.

It is uncertain whether these cases are serotonin syndrome which, in its most severe form, can resemble neuroleptic malignant syndrome.

As these events may result in potentially life-threatening conditions, patients should be monitored for the emergence of NMS-like signs and symptoms, especially if sertraline and an antipsychotic drug are taken concurrently.

Treatment with sertraline and any concomitant antipsychotic agent should be discontinued immediately if such events occur and supportive symptomatic treatment should be initiated.

DRUG INTERACTIONS

Drug Interactions Potential Effects of Coadministration of Drugs Highly Bound to Plasma Proteins Because sertraline is tightly bound to plasma protein, the administration of ZOLOFT (sertraline hydrochloride) to a patient taking another drug which is tightly bound to protein (e.g., warfarin, digitoxin) may cause a shift in plasma concentrations potentially resulting in an adverse effect.

Conversely, adverse effects may result from displacement of protein bound ZOLOFT by other tightly bound drugs.

In a study comparing prothrombin time AUC (0–120 hr) following dosing with warfarin (0.75 mg/kg) before and after 21 days of dosing with either ZOLOFT (50–200 mg/day) or placebo, there was a mean increase in prothrombin time of 8% relative to baseline for ZOLOFT compared to a 1% decrease for placebo (p<0.02).

The normalization of prothrombin time for the ZOLOFT group was delayed compared to the placebo group.

The clinical significance of this change is unknown.

Accordingly, prothrombin time should be carefully monitored when ZOLOFT therapy is initiated or stopped.

Cimetidine In a study assessing disposition of ZOLOFT (100 mg) on the second of 8 days of cimetidine administration (800 mg daily), there were significant increases in ZOLOFT mean AUC (50%), Cmax (24%) and half-life (26%) compared to the placebo group.

The clinical significance of these changes is unknown.

CNS Active Drugs In a study comparing the disposition of intravenously administered diazepam before and after 21 days of dosing with either ZOLOFT (50 to 200 mg/day escalating dose) or placebo, there was a 32% decrease relative to baseline in diazepam clearance for the ZOLOFT group compared to a 19% decrease relative to baseline for the placebo group (p<0.03).

There was a 23% increase in Tmax for desmethyldiazepam in the ZOLOFT group compared to a 20% decrease in the placebo group (p<0.03).

The clinical significance of these changes is unknown.

In a placebo-controlled trial in normal volunteers, the administration of two doses of ZOLOFT did not significantly alter steady-state lithium levels or the renal clearance of lithium.

Nonetheless, at this time, it is recommended that plasma lithium levels be monitored following initiation of ZOLOFT therapy with appropriate adjustments to the lithium dose.

In a controlled study of a single dose (2 mg) of pimozide, 200 mg sertraline (q.d.) co-administration to steady state was associated with a mean increase in pimozide AUC and Cmax of about 40%, but was not associated with any changes in EKG.

Since the highest recommended pimozide dose (10 mg) has not been evaluated in combination with sertraline, the effect on QT interval and PK parameters at doses higher than 2 mg at this time are not known.

While the mechanism of this interaction is unknown, due to the narrow therapeutic index of pimozide and due to the interaction noted at a low dose of pimozide, concomitant administration of ZOLOFT and pimozide should be contraindicated (see CONTRAINDICATIONS ).

Results of a placebo-controlled trial in normal volunteers suggest that chronic administration of sertraline 200 mg/day does not produce clinically important inhibition of phenytoin metabolism.

Nonetheless, at this time, it is recommended that plasma phenytoin concentrations be monitored following initiation of Zoloft therapy with appropriate adjustments to the phenytoin dose, particularly in patients with multiple underlying medical conditions and/or those receiving multiple concomitant medications.

The effect of Zoloft on valproate levels has not been evaluated in clinical trials.

In the absence of such data, it is recommended that plasma valproate levels be monitored following initiation of Zoloft therapy with appropriate adjustments to the valproate dose.

The risk of using ZOLOFT in combination with other CNS active drugs has not been systematically evaluated.

Consequently, caution is advised if the concomitant administration of ZOLOFT and such drugs is required.

There is limited controlled experience regarding the optimal timing of switching from other drugs effective in the treatment of major depressive disorder, obsessive-compulsive disorder, panic disorder, posttraumatic stress disorder, premenstrual dysphoric disorder and social anxiety disorder to ZOLOFT.

Care and prudent medical judgment should be exercised when switching, particularly from long-acting agents.

The duration of an appropriate washout period which should intervene before switching from one selective serotonin reuptake inhibitor (SSRI) to another has not been established.

Monoamine Oxidase Inhibitors See CONTRAINDICATIONS and WARNINGS .

Drugs Metabolized by P450 3A4 In three separate in vivo interaction studies, sertraline was co-administered with cytochrome P450 3A4 substrates, terfenadine, carbamazepine, or cisapride under steady-state conditions.

The results of these studies indicated that sertraline did not increase plasma concentrations of terfenadine, carbamazepine, or cisapride.

These data indicate that sertraline’s extent of inhibition of P450 3A4 activity is not likely to be of clinical significance.

Results of the interaction study with cisapride indicate that sertraline 200 mg (q.d.) induces the metabolism of cisapride (cisapride AUC and Cmax were reduced by about 35%).

Drugs Metabolized by P450 2D6 Many drugs effective in the treatment of major depressive disorder, e.g., the SSRIs, including sertraline, and most tricyclic antidepressant drugs effective in the treatment of major depressive disorder inhibit the biochemical activity of the drug metabolizing isozyme cytochrome P450 2D6 (debrisoquin hydroxylase), and, thus, may increase the plasma concentrations of co-administered drugs that are metabolized by P450 2D6.

The drugs for which this potential interaction is of greatest concern are those metabolized primarily by 2D6 and which have a narrow therapeutic index, e.g., the tricyclic antidepressant drugs effective in the treatment of major depressive disorder and the Type 1C antiarrhythmics propafenone and flecainide.

The extent to which this interaction is an important clinical problem depends on the extent of the inhibition of P450 2D6 by the antidepressant and the therapeutic index of the co-administered drug.

There is variability among the drugs effective in the treatment of major depressive disorder in the extent of clinically important 2D6 inhibition, and in fact sertraline at lower doses has a less prominent inhibitory effect on 2D6 than some others in the class.

Nevertheless, even sertraline has the potential for clinically important 2D6 inhibition.

Consequently, concomitant use of a drug metabolized by P450 2D6 with ZOLOFT may require lower doses than usually prescribed for the other drug.

Furthermore, whenever ZOLOFT is withdrawn from co-therapy, an increased dose of the co-administered drug may be required (see Tricyclic Antidepressant Drugs Effective in the Treatment of Major Depressive Disorder under PRECAUTIONS ).

Serotonergic Drugs Based on the mechanism of action of SNRIs and SSRIs, including Zoloft, and the potential for serotonin syndrome, caution is advised when SNRIs and SSRIs, including Zoloft, are coadministered with other drugs that may affect the serotonergic neutrotransmitter systems, such as triptans, linezolid (an antibiotic which is a reversible non-selective MAOI), lithium, tramadol, or St.

John’s Wort (see WARNINGS-Serotonin Syndrome ).

The concomitant use of Zoloft with other SSRIs, SNRIs or tryptophan is not recommended (see PRECAUTIONS – Drug Interactions ).

Triptans There have been rare post marketing reports of serotonin syndrome with use of an SNRI or an SSRI and a triptan.

If concomitant treatment of SNRIs and SSRIs, including Zoloft, with a triptan is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases (see WARNINGS – Serotonin Syndrome ).

Sumatriptan There have been rare post marketing reports describing patients with weakness, hyperreflexia, and incoordination following the use of a selective serotonin reuptake inhibitor (SSRI) and sumatriptan.

If concomitant treatment with sumatriptan and an SSRI (e.g., citalopram, fluoxetine, fluvoxamine, paroxetine, sertraline) is clinically warranted, appropriate observation of the patient is advised.

Tricyclic Antidepressant Drugs Effective in the Treatment of Major Depressive Disorder (TCAs) The extent to which SSRI–TCA interactions may pose clinical problems will depend on the degree of inhibition and the pharmacokinetics of the SSRI involved.

Nevertheless, caution is indicated in the co-administration of TCAs with ZOLOFT, because sertraline may inhibit TCA metabolism.

Plasma TCA concentrations may need to be monitored, and the dose of TCA may need to be reduced, if a TCA is co-administered with ZOLOFT (see Drugs Metabolized by P450 2D6 under PRECAUTIONS ).

Hypoglycemic Drugs In a placebo-controlled trial in normal volunteers, administration of ZOLOFT for 22 days (including 200 mg/day for the final 13 days) caused a statistically significant 16% decrease from baseline in the clearance of tolbutamide following an intravenous 1000 mg dose.

ZOLOFT administration did not noticeably change either the plasma protein binding or the apparent volume of distribution of tolbutamide, suggesting that the decreased clearance was due to a change in the metabolism of the drug.

The clinical significance of this decrease in tolbutamide clearance is unknown.

Atenolol ZOLOFT (100 mg) when administered to 10 healthy male subjects had no effect on the beta-adrenergic blocking ability of atenolol.

Digoxin In a placebo-controlled trial in normal volunteers, administration of ZOLOFT for 17 days (including 200 mg/day for the last 10 days) did not change serum digoxin levels or digoxin renal clearance.

Microsomal Enzyme Induction Preclinical studies have shown ZOLOFT to induce hepatic microsomal enzymes.

In clinical studies, ZOLOFT was shown to induce hepatic enzymes minimally as determined by a small (5%) but statistically significant decrease in antipyrine half-life following administration of 200 mg/day for 21 days.

This small change in antipyrine half-life reflects a clinically insignificant change in hepatic metabolism.

Drugs That Interfere With Hemostasis (Non-selective NSAIDs, Aspirin, Warfarin, etc.) Serotonin release by platelets plays an important role in hemostasis.

Epidemiological studies of the case-control and cohort design that have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding have also shown that concurrent use of an NSAID or aspirin may potentiate this risk of bleeding.

These studies have also shown that concurrent use of an NSAID or aspirin may potentiate this risk of bleeding.

Altered anticoagulant effects, including increased bleeding, have been reported when SSRIs or SNRIs are coadministered with warfarin.

Patients receiving warfarin therapy should be carefully monitored when Zoloft is initiated or discontinued.

Electroconvulsive Therapy There are no clinical studies establishing the risks or benefits of the combined use of electroconvulsive therapy (ECT) and ZOLOFT.

Alcohol Although ZOLOFT did not potentiate the cognitive and psychomotor effects of alcohol in experiments with normal subjects, the concomitant use of ZOLOFT and alcohol is not recommended.

OVERDOSAGE

Human Experience Of 1,027 cases of overdose involving sertraline hydrochloride worldwide, alone or with other drugs, there were 72 deaths (circa 1999).

Among 634 overdoses in which sertraline hydrochloride was the only drug ingested, 8 resulted in fatal outcome, 75 completely recovered, and 27 patients experienced sequelae after overdosage to include alopecia, decreased libido, diarrhea, ejaculation disorder, fatigue, insomnia, somnolence and serotonin syndrome.

The remaining 524 cases had an unknown outcome.

The most common signs and symptoms associated with non-fatal sertraline hydrochloride overdosage were somnolence, vomiting, tachycardia, nausea, dizziness, agitation and tremor.

The largest known ingestion was 13.5 grams in a patient who took sertraline hydrochloride alone and subsequently recovered.

However, another patient who took 2.5 grams of sertraline hydrochloride alone experienced a fatal outcome.

Other important adverse events reported with sertraline hydrochloride overdose (single or multiple drugs) include bradycardia, bundle branch block, coma, convulsions, delirium, hallucinations, hypertension, hypotension, manic reaction, pancreatitis, QT-interval prolongation, serotonin syndrome, stupor and syncope.

Overdose Management Treatment should consist of those general measures employed in the management of overdosage with any antidepressant.

Ensure an adequate airway, oxygenation and ventilation.

Monitor cardiac rhythm and vital signs.

General supportive and symptomatic measures are also recommended.

Induction of emesis is not recommended.

Gastric lavage with a large-bore orogastric tube with appropriate airway protection, if needed, may be indicated if performed soon after ingestion, or in symptomatic patients.

Activated charcoal should be administered.

Due to large volume of distribution of this drug, forced diuresis, dialysis, hemoperfusion and exchange transfusion are unlikely to be of benefit.

No specific antidotes for sertraline are known.

In managing overdosage, consider the possibility of multiple drug involvement.

The physician should consider contacting a poison control center on the treatment of any overdose.

Telephone numbers for certified poison control centers are listed in the Physicians’ Desk Reference ® (PDR ® ).

Chemical Structure

CLINICAL STUDIES

Clinical Trials Major Depressive Disorder The efficacy of ZOLOFT as a treatment for major depressive disorder was established in two placebo-controlled studies in adult outpatients meeting DSM-III criteria for major depressive disorder.

Study 1 was an 8-week study with flexible dosing of ZOLOFT in a range of 50 to 200 mg/day; the mean dose for completers was 145 mg/day.

Study 2 was a 6-week fixed-dose study, including ZOLOFT doses of 50, 100, and 200 mg/day.

Overall, these studies demonstrated ZOLOFT to be superior to placebo on the Hamilton Depression Rating Scale and the Clinical Global Impression Severity and Improvement scales.

Study 2 was not readily interpretable regarding a dose response relationship for effectiveness.

Study 3 involved depressed outpatients who had responded by the end of an initial 8-week open treatment phase on ZOLOFT 50–200 mg/day.

These patients (N=295) were randomized to continuation for 44 weeks on double-blind ZOLOFT 50–200 mg/day or placebo.

A statistically significantly lower relapse rate was observed for patients taking ZOLOFT compared to those on placebo.

The mean dose for completers was 70 mg/day.

Analyses for gender effects on outcome did not suggest any differential responsiveness on the basis of sex.

Obsessive-Compulsive Disorder (OCD) The effectiveness of ZOLOFT in the treatment of OCD was demonstrated in three multicenter placebo-controlled studies of adult outpatients (Studies 1–3).

Patients in all studies had moderate to severe OCD (DSM-III or DSM-III-R) with mean baseline ratings on the Yale–Brown Obsessive-Compulsive Scale (YBOCS) total score ranging from 23 to 25.

Study 1 was an 8-week study with flexible dosing of ZOLOFT in a range of 50 to 200 mg/day; the mean dose for completers was 186 mg/day.

Patients receiving ZOLOFT experienced a mean reduction of approximately 4 points on the YBOCS total score which was significantly greater than the mean reduction of 2 points in placebo-treated patients.

Study 2 was a 12-week fixed-dose study, including ZOLOFT doses of 50, 100, and 200 mg/day.

Patients receiving ZOLOFT doses of 50 and 200 mg/day experienced mean reductions of approximately 6 points on the YBOCS total score which were significantly greater than the approximately 3 point reduction in placebo-treated patients.

Study 3 was a 12-week study with flexible dosing of ZOLOFT in a range of 50 to 200 mg/day; the mean dose for completers was 185 mg/day.

Patients receiving ZOLOFT experienced a mean reduction of approximately 7 points on the YBOCS total score which was significantly greater than the mean reduction of approximately 4 points in placebo-treated patients.

Analyses for age and gender effects on outcome did not suggest any differential responsiveness on the basis of age or sex.

The effectiveness of ZOLOFT for the treatment of OCD was also demonstrated in a 12-week, multicenter, placebo-controlled, parallel group study in a pediatric outpatient population (children and adolescents, ages 6–17).

Patients receiving ZOLOFT in this study were initiated at doses of either 25 mg/day (children, ages 6–12) or 50 mg/day (adolescents, ages 13–17), and then titrated over the next four weeks to a maximum dose of 200 mg/day, as tolerated.

The mean dose for completers was 178 mg/day.

Dosing was once a day in the morning or evening.

Patients in this study had moderate to severe OCD (DSM-III-R) with mean baseline ratings on the Children’s Yale-Brown Obsessive-Compulsive Scale (CYBOCS) total score of 22.

Patients receiving sertraline experienced a mean reduction of approximately 7 units on the CYBOCS total score which was significantly greater than the 3 unit reduction for placebo patients.

Analyses for age and gender effects on outcome did not suggest any differential responsiveness on the basis of age or sex.

In a longer-term study, patients meeting DSM-III-R criteria for OCD who had responded during a 52-week single-blind trial on ZOLOFT 50–200 mg/day (n=224) were randomized to continuation of ZOLOFT or to substitution of placebo for up to 28 weeks of observation for discontinuation due to relapse or insufficient clinical response.

Response during the single-blind phase was defined as a decrease in the YBOCS score of ≥ 25% compared to baseline and a CGI-I of 1 (very much improved), 2 (much improved) or 3 (minimally improved).

Relapse during the double-blind phase was defined as the following conditions being met (on three consecutive visits for 1 and 2, and for visit 3 for condition 3): (1) YBOCS score increased by ≥ 5 points, to a minimum of 20, relative to baseline; (2) CGI-I increased by ≥ one point; and (3) worsening of the patient’s condition in the investigator’s judgment, to justify alternative treatment.

Insufficient clinical response indicated a worsening of the patient’s condition that resulted in study discontinuation, as assessed by the investigator.

Patients receiving continued ZOLOFT treatment experienced a significantly lower rate of discontinuation due to relapse or insufficient clinical response over the subsequent 28 weeks compared to those receiving placebo.

This pattern was demonstrated in male and female subjects.

Panic Disorder The effectiveness of ZOLOFT in the treatment of panic disorder was demonstrated in three double-blind, placebo-controlled studies (Studies 1–3) of adult outpatients who had a primary diagnosis of panic disorder (DSM-III-R), with or without agoraphobia.

Studies 1 and 2 were 10-week flexible dose studies.

ZOLOFT was initiated at 25 mg/day for the first week, and then patients were dosed in a range of 50–200 mg/day on the basis of clinical response and toleration.

The mean ZOLOFT doses for completers to 10 weeks were 131 mg/day and 144 mg/day, respectively, for Studies 1 and 2.

In these studies, ZOLOFT was shown to be significantly more effective than placebo on change from baseline in panic attack frequency and on the Clinical Global Impression Severity of Illness and Global Improvement scores.

The difference between ZOLOFT and placebo in reduction from baseline in the number of full panic attacks was approximately 2 panic attacks per week in both studies.

Study 3 was a 12-week fixed-dose study, including ZOLOFT doses of 50, 100, and 200 mg/day.

Patients receiving ZOLOFT experienced a significantly greater reduction in panic attack frequency than patients receiving placebo.

Study 3 was not readily interpretable regarding a dose response relationship for effectiveness.

Subgroup analyses did not indicate that there were any differences in treatment outcomes as a function of age, race, or gender.

In a longer-term study, patients meeting DSM-III-R criteria for Panic Disorder who had responded during a 52-week open trial on ZOLOFT 50–200 mg/day (n=183) were randomized to continuation of ZOLOFT or to substitution of placebo for up to 28 weeks of observation for discontinuation due to relapse or insufficient clinical response.

Response during the open phase was defined as a CGI-I score of 1 (very much improved) or 2 (much improved).

Relapse during the double-blind phase was defined as the following conditions being met on three consecutive visits: (1) CGI-I ≥ 3; (2) meets DSM-III-R criteria for Panic Disorder; (3) number of panic attacks greater than at baseline.

Insufficient clinical response indicated a worsening of the patient’s condition that resulted in study discontinuation, as assessed by the investigator.

Patients receiving continued ZOLOFT treatment experienced a significantly lower rate of discontinuation due to relapse or insufficient clinical response over the subsequent 28 weeks compared to those receiving placebo.

This pattern was demonstrated in male and female subjects.

Posttraumatic Stress Disorder (PTSD) The effectiveness of ZOLOFT in the treatment of PTSD was established in two multicenter placebo-controlled studies (Studies 1–2) of adult outpatients who met DSM-III-R criteria for PTSD.

The mean duration of PTSD for these patients was 12 years (Studies 1 and 2 combined) and 44% of patients (169 of the 385 patients treated) had secondary depressive disorder.

Studies 1 and 2 were 12-week flexible dose studies.

ZOLOFT was initiated at 25 mg/day for the first week, and patients were then dosed in the range of 50–200 mg/day on the basis of clinical response and toleration.

The mean ZOLOFT dose for completers was 146 mg/day and 151 mg/day, respectively for Studies 1 and 2.

Study outcome was assessed by the Clinician-Administered PTSD Scale Part 2 (CAPS) which is a multi-item instrument that measures the three PTSD diagnostic symptom clusters of reexperiencing/intrusion, avoidance/numbing, and hyperarousal as well as the patient-rated Impact of Event Scale (IES) which measures intrusion and avoidance symptoms.

ZOLOFT was shown to be significantly more effective than placebo on change from baseline to endpoint on the CAPS, IES and on the Clinical Global Impressions (CGI) Severity of Illness and Global Improvement scores.

In two additional placebo-controlled PTSD trials, the difference in response to treatment between patients receiving ZOLOFT and patients receiving placebo was not statistically significant.

One of these additional studies was conducted in patients similar to those recruited for Studies 1 and 2, while the second additional study was conducted in predominantly male veterans.

As PTSD is a more common disorder in women than men, the majority (76%) of patients in these trials were women (152 and 139 women on sertraline and placebo versus 39 and 55 men on sertraline and placebo; Studies 1 and 2 combined).

Post hoc exploratory analyses revealed a significant difference between ZOLOFT and placebo on the CAPS, IES and CGI in women, regardless of baseline diagnosis of comorbid major depressive disorder, but essentially no effect in the relatively smaller number of men in these studies.

The clinical significance of this apparent gender interaction is unknown at this time.

There was insufficient information to determine the effect of race or age on outcome.

In a longer-term study, patients meeting DSM-III-R criteria for PTSD who had responded during a 24-week open trial on ZOLOFT 50–200 mg/day (n=96) were randomized to continuation of ZOLOFT or to substitution of placebo for up to 28 weeks of observation for relapse.

Response during the open phase was defined as a CGI-I of 1 (very much improved) or 2 (much improved), and a decrease in the CAPS-2 score of > 30% compared to baseline.

Relapse during the double-blind phase was defined as the following conditions being met on two consecutive visits: (1) CGI-I ≥ 3; (2) CAPS-2 score increased by ≥ 30% and by ≥ 15 points relative to baseline; and (3) worsening of the patient’s condition in the investigator’s judgment.

Patients receiving continued ZOLOFT treatment experienced significantly lower relapse rates over the subsequent 28 weeks compared to those receiving placebo.

This pattern was demonstrated in male and female subjects.

Premenstrual Dysphoric Disorder (PMDD) The effectiveness of ZOLOFT for the treatment of PMDD was established in two double-blind, parallel group, placebo-controlled flexible dose trials (Studies 1 and 2) conducted over 3 menstrual cycles.

Patients in Study 1 met DSM-III-R criteria for Late Luteal Phase Dysphoric Disorder (LLPDD), the clinical entity now referred to as Premenstrual Dysphoric Disorder (PMDD) in DSM-IV.

Patients in Study 2 met DSM-IV criteria for PMDD.

Study 1 utilized daily dosing throughout the study, while Study 2 utilized luteal phase dosing for the 2 weeks prior to the onset of menses.

The mean duration of PMDD symptoms for these patients was approximately 10.5 years in both studies.

Patients on oral contraceptives were excluded from these trials; therefore, the efficacy of sertraline in combination with oral contraceptives for the treatment of PMDD is unknown.

Efficacy was assessed with the Daily Record of Severity of Problems (DRSP), a patient-rated instrument that mirrors the diagnostic criteria for PMDD as identified in the DSM-IV, and includes assessments for mood, physical symptoms, and other symptoms.

Other efficacy assessments included the Hamilton Depression Rating Scale (HAMD-17), and the Clinical Global Impression Severity of Illness (CGI-S) and Improvement (CGI-I) scores.

In Study 1, involving n=251 randomized patients, ZOLOFT treatment was initiated at 50 mg/day and administered daily throughout the menstrual cycle.

In subsequent cycles, patients were dosed in the range of 50–150 mg/day on the basis of clinical response and toleration.

The mean dose for completers was 102 mg/day.

ZOLOFT administered daily throughout the menstrual cycle was significantly more effective than placebo on change from baseline to endpoint on the DRSP total score, the HAMD-17 total score, and the CGI-S score, as well as the CGI-I score at endpoint.

In Study 2, involving n=281 randomized patients, ZOLOFT treatment was initiated at 50 mg/day in the late luteal phase (last 2 weeks) of each menstrual cycle and then discontinued at the onset of menses.

In subsequent cycles, patients were dosed in the range of 50–100 mg/day in the luteal phase of each cycle, on the basis of clinical response and toleration.

Patients who were titrated to 100 mg/day received 50 mg/day for the first 3 days of the cycle, then 100 mg/day for the remainder of the cycle.

The mean ZOLOFT dose for completers was 74 mg/day.

ZOLOFT administered in the late luteal phase of the menstrual cycle was significantly more effective than placebo on change from baseline to endpoint on the DRSP total score and the CGI-S score, as well as the CGI-I score at endpoint.

There was insufficient information to determine the effect of race or age on outcome in these studies.

Social Anxiety Disorder The effectiveness of ZOLOFT in the treatment of social anxiety disorder (also known as social phobia) was established in two multicenter placebo-controlled studies (Study 1 and 2) of adult outpatients who met DSM-IV criteria for social anxiety disorder.

Study 1 was a 12-week, multicenter, flexible dose study comparing ZOLOFT (50–200 mg/day) to placebo, in which ZOLOFT was initiated at 25 mg/day for the first week.

Study outcome was assessed by (a) the Liebowitz Social Anxiety Scale (LSAS), a 24-item clinician administered instrument that measures fear, anxiety and avoidance of social and performance situations, and by (b) the proportion of responders as defined by the Clinical Global Impression of Improvement (CGI-I) criterion of CGI-I ≤ 2 (very much or much improved).

ZOLOFT was statistically significantly more effective than placebo as measured by the LSAS and the percentage of responders.

Study 2 was a 20-week, multicenter, flexible dose study that compared ZOLOFT (50–200 mg/day) to placebo.

Study outcome was assessed by the (a) Duke Brief Social Phobia Scale (BSPS), a multi-item clinician-rated instrument that measures fear, avoidance and physiologic response to social or performance situations, (b) the Marks Fear Questionnaire Social Phobia Subscale (FQ-SPS), a 5-item patient-rated instrument that measures change in the severity of phobic avoidance and distress, and (c) the CGI-I responder criterion of ≤ 2.

ZOLOFT was shown to be statistically significantly more effective than placebo as measured by the BSPS total score and fear, avoidance and physiologic factor scores, as well as the FQ-SPS total score, and to have significantly more responders than placebo as defined by the CGI-I.

Subgroup analyses did not suggest differences in treatment outcome on the basis of gender.

There was insufficient information to determine the effect of race or age on outcome.

In a longer-term study, patients meeting DSM-IV criteria for social anxiety disorder who had responded while assigned to ZOLOFT (CGI-I of 1 or 2) during a 20-week placebo-controlled trial on ZOLOFT 50–200 mg/day were randomized to continuation of ZOLOFT or to substitution of placebo for up to 24 weeks of observation for relapse.

Relapse was defined as ≥ 2 point increase in the Clinical Global Impression – Severity of Illness (CGI-S) score compared to baseline or study discontinuation due to lack of efficacy.

Patients receiving ZOLOFT continuation treatment experienced a statistically significantly lower relapse rate over this 24-week study than patients randomized to placebo substitution.

GERIATRIC USE

Geriatric Use U.S.

geriatric clinical studies of ZOLOFT in major depressive disorder included 663 ZOLOFT-treated subjects ≥ 65 years of age, of those, 180 were ≥ 75 years of age.

No overall differences in the pattern of adverse reactions were observed in the geriatric clinical trial subjects relative to those reported in younger subjects (see ADVERSE REACTIONS ), and other reported experience has not identified differences in safety patterns between the elderly and younger subjects.

As with all medications, greater sensitivity of some older individuals cannot be ruled out.

There were 947 subjects in placebo-controlled geriatric clinical studies of ZOLOFT in major depressive disorder.

No overall differences in the pattern of efficacy were observed in the geriatric clinical trial subjects relative to those reported in younger subjects.

Other Adverse Events in Geriatric Patients.

In 354 geriatric subjects treated with ZOLOFT in placebo-controlled trials, the overall profile of adverse events was generally similar to that shown in Tables 2 and 3.

Urinary tract infection was the only adverse event not appearing in Tables 2 and 3 and reported at an incidence of at least 2% and at a rate greater than placebo in placebo-controlled trials.

SSRIS and SNRIs, including ZOLOFT, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse event (see PRECAUTIONS, Hyponatremia ).

INDICATIONS AND USAGE

Major Depressive Disorder ZOLOFT (sertraline hydrochloride) is indicated for the treatment of major depressive disorder in adults.

The efficacy of ZOLOFT in the treatment of a major depressive episode was established in six to eight week controlled trials of adult outpatients whose diagnoses corresponded most closely to the DSM-III category of major depressive disorder (see Clinical Trials under CLINICAL PHARMACOLOGY ).

A major depressive episode implies a prominent and relatively persistent depressed or dysphoric mood that usually interferes with daily functioning (nearly every day for at least 2 weeks); it should include at least 4 of the following 8 symptoms: change in appetite, change in sleep, psychomotor agitation or retardation, loss of interest in usual activities or decrease in sexual drive, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, and a suicide attempt or suicidal ideation.

The antidepressant action of ZOLOFT in hospitalized depressed patients has not been adequately studied.

The efficacy of ZOLOFT in maintaining an antidepressant response for up to 44 weeks following 8 weeks of open-label acute treatment (52 weeks total) was demonstrated in a placebo-controlled trial.

The usefulness of the drug in patients receiving ZOLOFT for extended periods should be reevaluated periodically (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Obsessive-Compulsive Disorder ZOLOFT is indicated for the treatment of obsessions and compulsions in patients with obsessive-compulsive disorder (OCD), as defined in the DSM-III-R; i.e., the obsessions or compulsions cause marked distress, are time-consuming, or significantly interfere with social or occupational functioning.

The efficacy of ZOLOFT was established in 12-week trials with obsessive-compulsive outpatients having diagnoses of obsessive-compulsive disorder as defined according to DSM-III or DSM-III-R criteria (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Obsessive-compulsive disorder is characterized by recurrent and persistent ideas, thoughts, impulses, or images (obsessions) that are ego-dystonic and/or repetitive, purposeful, and intentional behaviors (compulsions) that are recognized by the person as excessive or unreasonable.

The efficacy of ZOLOFT in maintaining a response, in patients with OCD who responded during a 52-week treatment phase while taking ZOLOFT and were then observed for relapse during a period of up to 28 weeks, was demonstrated in a placebo-controlled trial (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Nevertheless, the physician who elects to use ZOLOFT for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION ).

Panic Disorder ZOLOFT is indicated for the treatment of panic disorder in adults, with or without agoraphobia, as defined in DSM-IV.

Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks.

The efficacy of ZOLOFT was established in three 10–12 week trials in adult panic disorder patients whose diagnoses corresponded to the DSM-III-R category of panic disorder (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Panic disorder (DSM-IV) is characterized by recurrent unexpected panic attacks, i.e., a discrete period of intense fear or discomfort in which four (or more) of the following symptoms develop abruptly and reach a peak within 10 minutes: (1) palpitations, pounding heart, or accelerated heart rate; (2) sweating; (3) trembling or shaking; (4) sensations of shortness of breath or smothering; (5) feeling of choking; (6) chest pain or discomfort; (7) nausea or abdominal distress; (8) feeling dizzy, unsteady, lightheaded, or faint; (9) derealization (feelings of unreality) or depersonalization (being detached from oneself); (10) fear of losing control; (11) fear of dying; (12) paresthesias (numbness or tingling sensations); (13) chills or hot flushes.

The efficacy of ZOLOFT in maintaining a response, in adult patients with panic disorder who responded during a 52-week treatment phase while taking ZOLOFT and were then observed for relapse during a period of up to 28 weeks, was demonstrated in a placebo-controlled trial (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Nevertheless, the physician who elects to use ZOLOFT for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION ).

Posttraumatic Stress Disorder (PTSD) ZOLOFT (sertraline hydrochloride) is indicated for the treatment of posttraumatic stress disorder in adults.

The efficacy of ZOLOFT in the treatment of PTSD was established in two 12-week placebo-controlled trials of adult outpatients whose diagnosis met criteria for the DSM-III-R category of PTSD (see Clinical Trials under CLINICAL PHARMACOLOGY ).

PTSD, as defined by DSM-III-R/IV, requires exposure to a traumatic event that involved actual or threatened death or serious injury, or threat to the physical integrity of self or others, and a response which involves intense fear, helplessness, or horror.

Symptoms that occur as a result of exposure to the traumatic event include reexperiencing of the event in the form of intrusive thoughts, flashbacks or dreams, and intense psychological distress and physiological reactivity on exposure to cues to the event; avoidance of situations reminiscent of the traumatic event, inability to recall details of the event, and/or numbing of general responsiveness manifested as diminished interest in significant activities, estrangement from others, restricted range of affect, or sense of foreshortened future; and symptoms of autonomic arousal including hypervigilance, exaggerated startle response, sleep disturbance, impaired concentration, and irritability or outbursts of anger.

A PTSD diagnosis requires that the symptoms are present for at least a month and that they cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

The efficacy of ZOLOFT in maintaining a response in adult patients with PTSD for up to 28 weeks following 24 weeks of open-label treatment was demonstrated in a placebo-controlled trial.

Nevertheless, the physician who elects to use ZOLOFT for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION ).

Premenstrual Dysphoric Disorder (PMDD) ZOLOFT is indicated for the treatment of premenstrual dysphoric disorder (PMDD) in adults.

The efficacy of ZOLOFT in the treatment of PMDD was established in 2 placebo-controlled trials of female adult outpatients treated for 3 menstrual cycles who met criteria for the DSM-III-R/IV category of PMDD (see Clinical Trials under CLINICAL PHARMACOLOGY ).

The essential features of PMDD include markedly depressed mood, anxiety or tension, affective lability, and persistent anger or irritability.

Other features include decreased interest in activities, difficulty concentrating, lack of energy, change in appetite or sleep, and feeling out of control.

Physical symptoms associated with PMDD include breast tenderness, headache, joint and muscle pain, bloating and weight gain.

These symptoms occur regularly during the luteal phase and remit within a few days following onset of menses; the disturbance markedly interferes with work or school or with usual social activities and relationships with others.

In making the diagnosis, care should be taken to rule out other cyclical mood disorders that may be exacerbated by treatment with an antidepressant.

The effectiveness of ZOLOFT in long-term use, that is, for more than 3 menstrual cycles, has not been systematically evaluated in controlled trials.

Therefore, the physician who elects to use ZOLOFT for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION ).

Social Anxiety Disorder ZOLOFT (sertraline hydrochloride) is indicated for the treatment of social anxiety disorder, also known as social phobia in adults.

The efficacy of ZOLOFT in the treatment of social anxiety disorder was established in two placebo-controlled trials of adult outpatients with a diagnosis of social anxiety disorder as defined by DSM-IV criteria (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Social anxiety disorder, as defined by DSM-IV, is characterized by marked and persistent fear of social or performance situations involving exposure to unfamiliar people or possible scrutiny by others and by fears of acting in a humiliating or embarrassing way.

Exposure to the feared social situation almost always provokes anxiety and feared social or performance situations are avoided or else are endured with intense anxiety or distress.

In addition, patients recognize that the fear is excessive or unreasonable and the avoidance and anticipatory anxiety of the feared situation is associated with functional impairment or marked distress.

The efficacy of ZOLOFT in maintaining a response in adult patients with social anxiety disorder for up to 24 weeks following 20 weeks of ZOLOFT treatment was demonstrated in a placebo-controlled trial.

Physicians who prescribe ZOLOFT for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see Clinical Trials under CLINICAL PHARMACOLOGY ).

PEDIATRIC USE

Pediatric Use The efficacy of ZOLOFT for the treatment of obsessive-compulsive disorder was demonstrated in a 12-week, multicenter, placebo-controlled study with 187 outpatients ages 6–17 (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Safety and effectiveness in the pediatric population other than pediatric patients with OCD have not been established (see BOX WARNING and WARNINGS-Clinical Worsening and Suicide Risk) .

Two placebo controlled trials (n=373) in pediatric patients with MDD have been conducted with Zoloft, and the data were not sufficient to support a claim for use in pediatric patients.

Anyone considering the use of Zoloft in a child or adolescent must balance the potential risks with the clinical need.

The safety of ZOLOFT use in children and adolescents with OCD, ages 6–18, was evaluated in a 12-week, multicenter, placebo-controlled study with 187 outpatients, ages 6–17, and in a flexible dose, 52 week open extension study of 137 patients, ages 6–18, who had completed the initial 12-week, double-blind, placebo-controlled study.

ZOLOFT was administered at doses of either 25 mg/day (children, ages 6–12) or 50 mg/day (adolescents, ages 13–18) and then titrated in weekly 25 mg/day or 50 mg/day increments, respectively, to a maximum dose of 200 mg/day based upon clinical response.

The mean dose for completers was 157 mg/day.

In the acute 12 week pediatric study and in the 52 week study, ZOLOFT had an adverse event profile generally similar to that observed in adults.

Sertraline pharmacokinetics were evaluated in 61 pediatric patients between 6 and 17 years of age with major depressive disorder or OCD and revealed similar drug exposures to those of adults when plasma concentration was adjusted for weight (see Pharmacokinetics under CLINICAL PHARMACOLOGY ).

Approximately 600 patients with major depressive disorder or OCD between 6 and 17 years of age have received ZOLOFT in clinical trials, both controlled and uncontrolled.

The adverse event profile observed in these patients was generally similar to that observed in adult studies with ZOLOFT (see ADVERSE REACTIONS ).

As with other SSRIs, decreased appetite and weight loss have been observed in association with the use of ZOLOFT.

In a pooled analysis of two 10-week, double-blind, placebo-controlled, flexible dose (50–200 mg) outpatient trials for major depressive disorder (n=373), there was a difference in weight change between sertraline and placebo of roughly 1 kilogram, for both children (ages 6–11) and adolescents (ages 12–17), in both cases representing a slight weight loss for sertraline compared to a slight gain for placebo.

At baseline the mean weight for children was 39.0 kg for sertraline and 38.5 kg for placebo.

At baseline the mean weight for adolescents was 61.4 kg for sertraline and 62.5 kg for placebo.

There was a bigger difference between sertraline and placebo in the proportion of outliers for clinically important weight loss in children than in adolescents.

For children, about 7% had a weight loss > 7% of body weight compared to none of the placebo patients; for adolescents, about 2% had a weight loss > 7% of body weight compared to about 1% of the placebo patients.

A subset of these patients who completed the randomized controlled trials (sertraline n=99, placebo n=122) were continued into a 24-week, flexible-dose, open-label, extension study.

A mean weight loss of approximately 0.5 kg was seen during the first eight weeks of treatment for subjects with first exposure to sertraline during the open-label extension study, similar to mean weight loss observed among sertraline treated subjects during the first eight weeks of the randomized controlled trials.

The subjects continuing in the open label study began gaining weight compared to baseline by week 12 of sertraline treatment.

Those subjects who completed 34 weeks of sertraline treatment (10 weeks in a placebo controlled trial + 24 weeks open label, n=68) had weight gain that was similar to that expected using data from age-adjusted peers.

Regular monitoring of weight and growth is recommended if treatment of a pediatric patient with an SSRI is to be continued long term.

Safety and effectiveness in pediatric patients below the age of 6 have not been established.

The risks, if any, that may be associated with ZOLOFT’s use beyond 1 year in children and adolescents with OCD or major depressive disorder have not been systematically assessed.

The prescriber should be mindful that the evidence relied upon to conclude that sertraline is safe for use in children and adolescents derives from clinical studies that were 10 to 52 weeks in duration and from the extrapolation of experience gained with adult patients.

In particular, there are no studies that directly evaluate the effects of long-term sertraline use on the growth, development, and maturation of children and adolescents.

Although there is no affirmative finding to suggest that sertraline possesses a capacity to adversely affect growth, development or maturation, the absence of such findings is not compelling evidence of the absence of the potential of sertraline to have adverse effects in chronic use (see WARNINGS – Clinical Worsening and Suicide Risk ).

PREGNANCY

Pregnancy–Pregnancy Category C Reproduction studies have been performed in rats and rabbits at doses up to 80 mg/kg/day and 40 mg/kg/day, respectively.

These doses correspond to approximately 4 times the maximum recommended human dose (MRHD) on a mg/m 2 basis.

There was no evidence of teratogenicity at any dose level.

When pregnant rats and rabbits were given sertraline during the period of organogenesis, delayed ossification was observed in fetuses at doses of 10 mg/kg (0.5 times the MRHD on a mg/m 2 basis) in rats and 40 mg/kg (4 times the MRHD on a mg/m 2 basis) in rabbits.

When female rats received sertraline during the last third of gestation and throughout lactation, there was an increase in the number of stillborn pups and in the number of pups dying during the first 4 days after birth.

Pup body weights were also decreased during the first four days after birth.

These effects occurred at a dose of 20 mg/kg (1 times the MRHD on a mg/m 2 basis).

The no effect dose for rat pup mortality was 10 mg/kg (0.5 times the MRHD on a mg/m 2 basis).

The decrease in pup survival was shown to be due to in utero exposure to sertraline.

The clinical significance of these effects is unknown.

There are no adequate and well-controlled studies in pregnant women.

ZOLOFT (sertraline hydrochloride) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

NUSRING MOTHERS

Nursing Mothers It is not known whether, and if so in what amount, sertraline or its metabolites are excreted in human milk.

Because many drugs are excreted in human milk, caution should be exercised when ZOLOFT is administered to a nursing woman.

BOXED WARNING

Suicidality and Antidepressant Drugs Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders.

Anyone considering the use of Zoloft or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need.

Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older.

Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide.

Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior.

Families and caregivers should be advised of the need for close observation and communication with the prescriber.

Zoloft is not approved for use in pediatric patients except for patients with obsessive compulsive disorder (OCD).

(See Warnings: Clinical Worsening and Suicide Risk , Precautions: Information for Patients , and Precautions: Pediatric Use )

INFORMATION FOR PATIENTS

Information for Patients Prescribers or other health professionals should inform patients, their families, and their caregivers about the benefits and risks associated with treatment with Zoloft and should counsel them in its appropriate use.

A patient Medication Guide about “Antidepressant Medicines, Depression and other Serious Mental Illness, and Suicidal Thoughts or Actions: is available for ZOLOFT.

The prescriber or health professional should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents.

Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have.

The complete text of the Medication Guide is reprinted at the end of this document.

Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking ZOLOFT.

Clinical Worsening and Suicide Risk Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down.

Families and caregivers of patients should be advised to look for the emergence of such symptoms on a day-to-day basis, since changes may be abrupt.

Such symptoms should be reported to the patient’s prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient’s presenting symptoms.

Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication.

Patients should be cautioned about the risk of serotonin syndrome with the concomitant use of SNRIs and SSRIs, including Zoloft, and triptans, tramadol, or other serotonergic agents.

Patients should be told that although ZOLOFT has not been shown to impair the ability of normal subjects to perform tasks requiring complex motor and mental skills in laboratory experiments, drugs that act upon the central nervous system may affect some individuals adversely.

Therefore, patients should be told that until they learn how they respond to ZOLOFT they should be careful doing activities when they need to be alert, such as driving a car or operating machinery.

Patients should be cautioned about the concomitant use of Zoloft and NSAIDs, aspirin, warfarin, or other drugs that affect coagulation since combined use of psychotropic drugs that interfere with serotonin reuptake and these agents has been associated with an increased risk of bleeding.

Patients should be told that although ZOLOFT has not been shown in experiments with normal subjects to increase the mental and motor skill impairments caused by alcohol, the concomitant use of ZOLOFT and alcohol is not advised.

Patients should be told that while no adverse interaction of ZOLOFT with over-the-counter (OTC) drug products is known to occur, the potential for interaction exists.

Thus, the use of any OTC product should be initiated cautiously according to the directions of use given for the OTC product.

Patients should be advised to notify their physician if they become pregnant or intend to become pregnant during therapy.

Patients should be advised to notify their physician if they are breast feeding an infant.

ZOLOFT oral concentrate is contraindicated with ANTABUSE (disulfiram) due to the alcohol content of the concentrate.

ZOLOFT Oral Concentrate contains 20 mg/mL of sertraline (as the hydrochloride) as the active ingredient and 12% alcohol.

ZOLOFT Oral Concentrate must be diluted before use.

Just before taking, use the dropper provided to remove the required amount of ZOLOFT Oral Concentrate and mix with 4 oz (1/2 cup) of water, ginger ale, lemon/lime soda, lemonade or orange juice ONLY.

Do not mix ZOLOFT Oral Concentrate with anything other than the liquids listed.

The dose should be taken immediately after mixing.

Do not mix in advance.

At times, a slight haze may appear after mixing; this is normal.

Note that caution should be exercised for persons with latex sensitivity, as the dropper dispenser contains dry natural rubber.

DOSAGE AND ADMINISTRATION

Initial Treatment Dosage for Adults Major Depressive Disorder and Obsessive-Compulsive Disorder ZOLOFT treatment should be administered at a dose of 50 mg once daily.

Panic Disorder, Posttraumatic Stress Disorder and Social Anxiety Disorder ZOLOFT treatment should be initiated with a dose of 25 mg once daily.

After one week, the dose should be increased to 50 mg once daily.

While a relationship between dose and effect has not been established for major depressive disorder, OCD, panic disorder, PTSD or social anxiety disorder, patients were dosed in a range of 50–200 mg/day in the clinical trials demonstrating the effectiveness of ZOLOFT for the treatment of these indications.

Consequently, a dose of 50 mg, administered once daily, is recommended as the initial therapeutic dose.

Patients not responding to a 50 mg dose may benefit from dose increases up to a maximum of 200 mg/day.

Given the 24 hour elimination half-life of ZOLOFT, dose changes should not occur at intervals of less than 1 week.

Premenstrual Dysphoric Disorder ZOLOFT treatment should be initiated with a dose of 50 mg/day, either daily throughout the menstrual cycle or limited to the luteal phase of the menstrual cycle, depending on physician assessment.

While a relationship between dose and effect has not been established for PMDD, patients were dosed in the range of 50–150 mg/day with dose increases at the onset of each new menstrual cycle (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Patients not responding to a 50 mg/day dose may benefit from dose increases (at 50 mg increments/menstrual cycle) up to 150 mg/day when dosing daily throughout the menstrual cycle, or 100 mg/day when dosing during the luteal phase of the menstrual cycle.

If a 100 mg/day dose has been established with luteal phase dosing, a 50 mg/day titration step for three days should be utilized at the beginning of each luteal phase dosing period.

ZOLOFT should be administered once daily, either in the morning or evening.

Dosage for Pediatric Population (Children and Adolescents) Obsessive-Compulsive Disorder ZOLOFT treatment should be initiated with a dose of 25 mg once daily in children (ages 6–12) and at a dose of 50 mg once daily in adolescents (ages 13–17).

While a relationship between dose and effect has not been established for OCD, patients were dosed in a range of 25–200 mg/day in the clinical trials demonstrating the effectiveness of ZOLOFT for pediatric patients (6–17 years) with OCD.

Patients not responding to an initial dose of 25 or 50 mg/day may benefit from dose increases up to a maximum of 200 mg/day.

For children with OCD, their generally lower body weights compared to adults should be taken into consideration in advancing the dose, in order to avoid excess dosing.

Given the 24 hour elimination half-life of ZOLOFT, dose changes should not occur at intervals of less than 1 week.

ZOLOFT should be administered once daily, either in the morning or evening.

Maintenance/Continuation/Extended Treatment Major Depressive Disorder It is generally agreed that acute episodes of major depressive disorder require several months or longer of sustained pharmacologic therapy beyond response to the acute episode.

Systematic evaluation of ZOLOFT has demonstrated that its antidepressant efficacy is maintained for periods of up to 44 weeks following 8 weeks of initial treatment at a dose of 50–200 mg/day (mean dose of 70 mg/day) (see Clinical Trials under CLINICAL PHARMACOLOGY ).

It is not known whether the dose of ZOLOFT needed for maintenance treatment is identical to the dose needed to achieve an initial response.

Patients should be periodically reassessed to determine the need for maintenance treatment.

Posttraumatic Stress Disorder It is generally agreed that PTSD requires several months or longer of sustained pharmacological therapy beyond response to initial treatment.

Systematic evaluation of ZOLOFT has demonstrated that its efficacy in PTSD is maintained for periods of up to 28 weeks following 24 weeks of treatment at a dose of 50–200 mg/day (see Clinical Trials under CLINICAL PHARMACOLOGY ).

It is not known whether the dose of ZOLOFT needed for maintenance treatment is identical to the dose needed to achieve an initial response.

Patients should be periodically reassessed to determine the need for maintenance treatment.

Social Anxiety Disorder Social anxiety disorder is a chronic condition that may require several months or longer of sustained pharmacological therapy beyond response to initial treatment.

Systematic evaluation of ZOLOFT has demonstrated that its efficacy in social anxiety disorder is maintained for periods of up to 24 weeks following 20 weeks of treatment at a dose of 50–200 mg/day (see Clinical Trials under CLINICAL PHARMACOLOGY ).

Dosage adjustments should be made to maintain patients on the lowest effective dose and patients should be periodically reassessed to determine the need for long-term treatment.

Obsessive-Compulsive Disorder and Panic Disorder It is generally agreed that OCD and Panic Disorder require several months or longer of sustained pharmacological therapy beyond response to initial treatment.

Systematic evaluation of continuing ZOLOFT for periods of up to 28 weeks in patients with OCD and Panic Disorder who have responded while taking ZOLOFT during initial treatment phases of 24 to 52 weeks of treatment at a dose range of 50–200 mg/day has demonstrated a benefit of such maintenance treatment (see Clinical Trials under CLINICAL PHARMACOLOGY ).

It is not known whether the dose of ZOLOFT needed for maintenance treatment is identical to the dose needed to achieve an initial response.

Nevertheless, patients should be periodically reassessed to determine the need for maintenance treatment.

Premenstrual Dysphoric Disorder The effectiveness of ZOLOFT in long-term use, that is, for more than 3 menstrual cycles, has not been systematically evaluated in controlled trials.

However, as women commonly report that symptoms worsen with age until relieved by the onset of menopause, it is reasonable to consider continuation of a responding patient.

Dosage adjustments, which may include changes between dosage regimens (e.g., daily throughout the menstrual cycle versus during the luteal phase of the menstrual cycle), may be needed to maintain the patient on the lowest effective dosage and patients should be periodically reassessed to determine the need for continued treatment.

Switching Patients to or from a Monoamine Oxidase Inhibitor At least 14 days should elapse between discontinuation of an MAOI and initiation of therapy with ZOLOFT.

In addition, at least 14 days should be allowed after stopping ZOLOFT before starting an MAOI (see CONTRAINDICATIONS and WARNINGS ).

Special Populations Dosage for Hepatically Impaired Patients The use of sertraline in patients with liver disease should be approached with caution.

The effects of sertraline in patients with moderate and severe hepatic impairment have not been studied.

If sertraline is administered to patients with liver impairment, a lower or less frequent dose should be used (see CLINICAL PHARMACOLOGY and PRECAUTIONS ).

Treatment of Pregnant Women During the Third Trimester Neonates exposed to ZOLOFT and other SSRIs or SNRIs, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding (see PRECAUTIONS ).

When treating pregnant women with ZOLOFT during the third trimester, the physician should carefully consider the potential risks and benefits of treatment.

The physician may consider tapering ZOLOFT in the third trimester.

Discontinuation of Treatment with Zoloft Symptoms associated with discontinuation of ZOLOFT and other SSRIs and SNRIs, have been reported (see PRECAUTIONS ).

Patients should be monitored for these symptoms when discontinuing treatment.

A gradual reduction in the dose rather than abrupt cessation is recommended whenever possible.

If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered.

Subsequently, the physician may continue decreasing the dose but at a more gradual rate.

ZOLOFT Oral Concentrate ZOLOFT Oral Concentrate contains 20 mg/mL of sertraline (as the hydrochloride) as the active ingredient and 12% alcohol.
