Augmentin 125 MG / 31.25 MG per 5 ML Oral Suspension
DRUG INTERACTIONS
7 Co‑administration with probenecid is not recommended.
(7.1) Concomitant use of AUGMENTIN and oral anticoagulants may increase the prolongation of prothrombin time.
(7.2 ) Coadministration with allopurinol increases the risk of rash.
(7.3) AUGMENTIN may reduce efficacy of oral contraceptives.
(7.4) 7.1 Probenecid Probenecid decreases the renal tubular secretion of amoxicillin but does not delay renal excretion of clavulanic acid.
Concurrent use with AUGMENTIN may result in increased and prolonged blood concentrations of amoxicillin.
Coadministration of probenecid is not recommended.
7.2 Oral Anticoagulants Abnormal prolongation of prothrombin time (increased international normalized ratio [INR]) has been reported in patients receiving amoxicillin and oral anticoagulants.
Appropriate monitoring should be undertaken when anticoagulants are prescribed concurrently with AUGMENTIN.
Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation.
7.3 Allopurinol The concurrent administration of allopurinol and amoxicillin increases the incidence of rashes in patients receiving both drugs as compared to patients receiving amoxicillin alone.
It is not known whether this potentiation of amoxicillin rashes is due to allopurinol or the hyperuricemia present in these patients.
7.4 Oral Contraceptives AUGMENTIN may affect intestinal flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives.
7.5 Effects on Laboratory Tests High urine concentrations of amoxicillin may result in false-positive reactions when testing for the presence of glucose in urine using CLINITEST ® , Benedict’s Solution, or Fehling’s Solution.
Since this effect may also occur with AUGMENTIN, it is recommended that glucose tests based on enzymatic glucose oxidase reactions be used.
Following administration of amoxicillin to pregnant women, a transient decrease in plasma concentration of total conjugated estriol, estriol-glucuronide, conjugated estrone, and estradiol has been noted.
OVERDOSAGE
10 In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures as required.
A prospective study of 51 pediatric patients at a poison-control center suggested that overdosages of less than 250 mg/kg of amoxicillin are not associated with significant clinical symptoms 1 .
Interstitial nephritis resulting in oliguric renal failure has been reported in patients after overdosage with amoxicillin/clavulanate potassium.
Crystalluria, in some cases leading to renal failure, has also been reported after amoxicillin/clavulanate potassium overdosage in adult and pediatric patients.
In case of overdosage, adequate fluid intake and diuresis should be maintained to reduce the risk of amoxicillin/clavulanate potassium crystalluria.
Renal impairment appears to be reversible with cessation of drug administration.
High blood levels may occur more readily in patients with impaired renal function because of decreased renal clearance of amoxicillin/clavulanate potassium.
Amoxicillin/clavulanate potassium may be removed from circulation by hemodialysis .
[see Dosage and Administration (2.3 )]
DESCRIPTION
11 AUGMENTIN is an oral antibacterial combination consisting of amoxicillin and the beta‑lactamase inhibitor, clavulanate potassium (the potassium salt of clavulanic acid).
Amoxicillin is an analog of ampicillin, derived from the basic penicillin nucleus, 6‑aminopenicillanic acid.
The amoxicillin molecular formula is C 16 H 19 N 3 O 5 S•3H 2 O, and the molecular weight is 419.46.
Chemically, amoxicillin is (2S,5R,6R)-6-[(R)-(-)-2-Amino-2-(p-hydroxyphenyl)acetamido]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid trihydrate and may be represented structurally as: Clavulanic acid is produced by the fermentation of Streptomyces clavuligerus .
It is a beta-lactam structurally related to the penicillins and possesses the ability to inactivate some beta‑lactamases by blocking the active sites of these enzymes.
The clavulanate potassium molecular formula is C 8 H 8 KNO 5 , and the molecular weight is 237.25.
Chemically, clavulanate potassium is potassium (Z)(2R,5R)-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo[3.2.0]-heptane-2-carboxylate and may be represented structurally as: Inactive Ingredients: Tablets- Colloidal silicon dioxide, hypromellose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, sodium starch glycolate, and titanium dioxide.

CLINICAL STUDIES
14 14.1 Lower Respiratory Tract and Complicated Urinary Tract Infections Data from 2 pivotal trials in 1,191 patients treated for either lower respiratory tract infections or complicated urinary tract infections compared a regimen of 875‑mg tablets of AUGMENTIN every 12 hours to 500‑mg tablets of AUGMENTIN dosed every 8 hours (584 and 607 patients, respectively).
Comparable efficacy was demonstrated between the every 12 hours and every 8 hours dosing regimens.
There was no significant difference in the percentage of adverse events in each group.
The most frequently reported adverse event was diarrhea; incidence rates were similar for the 875‑mg every 12 hours and 500‑mg every 8 hours dosing regimens (15% and 14%, respectively); however, there was a statistically significant difference (p < 0.05) in rates of severe diarrhea or withdrawals with diarrhea between the regimens: 1% for 875‑mg every 12 hours regimen versus 2% for the 500‑mg every 8 hours regimen.
In one of these pivotal trials, patients with either pyelonephritis (n = 361) or a complicated urinary tract infection (i.e., patients with abnormalities of the urinary tract that predispose to relapse of bacteriuria following eradication, n = 268) were randomized (1:1) to receive either 875‑mg tablets of AUGMENTIN every 12 hours (n=308) or 500‑mg tablets of AUGMENTIN every 8 hours (n=321).
The number of bacteriologically evaluable patients was comparable between the two dosing regimens.
AUGMENTIN produced comparable bacteriological success rates in patients assessed 2 to 4 days immediately following end of therapy.
The bacteriologic efficacy rates were comparable at one of the follow‑up visits (5 to 9 days post‑therapy) and at a late post‑therapy visit (in the majority of cases, this was 2 to 4 weeks post-therapy), as seen in Table 7.
Table 7: Bacteriologic efficacy rates for AUGMENTIN Time Post Therapy 875 mg every 12 hours % (n) 500 mg every 8 hours % (n) 2 to 4 days 81% (58) 80% (54) 5 to 9 days 58% (41) 52% (52) 2 to 4 weeks 52% (101) 55% (104) As noted before, though there was no significant difference in the percentage of adverse events in each group, there was a statistically significant difference in rates of severe diarrhea or withdrawals with diarrhea between the regimens.
14.2 Acute Bacterial Otitis Media and Diarrhea in Pediatric Patients One US/Canadian clinical trial was conducted which compared 45/6.4 mg/kg/day (divided every 12 hours) of AUGMENTIN for 10 days versus 40/10 mg/kg/day (divided every 8 hours) of AUGMENTIN for 10 days in the treatment of acute otitis media.
Only the suspension formulations were used in this trial.
A total of 575 pediatric patients (aged 2 months to 12 years) were enrolled, with an even distribution among the 2 treatment groups and a comparable number of patients were evaluable (i.e., ³ 84%) per treatment group.
Otitis media‑specific criteria were required for eligibility and a strong correlation was found at the end of therapy and follow‑up between these criteria and physician assessment of clinical response.
The clinical efficacy rates at the end of therapy visit (defined as 2‑4 days after the completion of therapy) and at the follow‑up visit (defined as 22‑28 days post‑completion of therapy) were comparable for the 2 treatment groups, with the following cure rates obtained for the evaluable patients: At end of therapy, 87% (n = 265) and 82% (n = 260) for 45 mg/kg/day every 12 hours and 40 mg/kg/day every 8 hours, respectively.
At follow‑up, 67% (n = 249) and 69% (n = 243) for 45 mg/kg/day every 12 hours and 40 mg/kg/day every 8 hours, respectively.
Diarrhea was defined as either: (a) 3 or more watery or 4 or more loose/watery stools in 1 day; OR (b) 2 watery stools per day or 3 loose/watery stools per day for 2 consecutive days.
The incidence of diarrhea was significantly lower in patients who received the every 12 hours regimen compared to patients who received the every 8 hours regimen (14% and 34%, respectively).
In addition, the number of patients with either severe diarrhea or who were withdrawn with diarrhea was significantly lower in the every 12 hours treatment group (3% and 8% for the every 12 hours/10 day and every 8 hours/10 day, respectively).
In the every 12 hours treatment group, 3 patients (1%) were withdrawn with an allergic reaction, while 1 patient in the every 8 hours group was withdrawn for this reason.
The number of patients with a candidal infection of the diaper area was 4% and 6% for the every 12 hours and every 8 hours groups, respectively.
It is not known if the finding of a statistically significant reduction in diarrhea with the oral suspensions dosed every 12 hours, versus suspensions dosed every 8 hours, can be extrapolated to the chewable tablets.
The presence of mannitol in the chewable tablets may contribute to a different diarrhea profile.
The every 12 hour oral suspensions (200 mg/5 mL and 400 mg/5 mL) are sweetened with aspartame.

GERIATRIC USE
8.5 Geriatric Use Of the 3,119 patients in an analysis of clinical studies of AUGMENTIN, 32% were ≥65 years old, and 14% were ≥75 years old.
No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
This drug 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.

MECHANISM OF ACTION
12.1 Mechanism of Action AUGMENTIN is an antibacterial drug.
[see Microbiology 12.4 ]
INDICATIONS AND USAGE
1 To reduce the development of drug‑resistant bacteria and maintain the effectiveness of AUGMENTIN (amoxicillin/clavulanate potassium) and other antibacterial drugs, AUGMENTIN should be used only to treat 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.
AUGMENTIN ® is a combination penicillin-class antibacterial and beta-lactamase inhibitor indicated in the treatment of infections due to susceptible isolates of the designated bacteria in the conditions listed below*: AUGMENTIN is a combination penicillin-class antibacterial and beta‑lactamase inhibitor indicated for treatment of the following: Lower respiratory tract infections (1.1) Acute bacterial otitis media (1.2) Sinusitis (1.3) Skin and skin structure infections (1.4) Urinary tract infections (1.5) 1.1 Lower Respiratory Tract Infections caused by beta‑lactamase–producing isolates of Haemophilus influenzae and Moraxella catarrhalis .
1.2 Acute Bacterial Otitis Media caused by beta‑lactamase–producing isolates of H.
influenzae and M.
catarrhalis .
1.3 Sinusitis caused by beta‑lactamase–producing isolates of H.
influenzae and M.
catarrhalis .
1.4 Skin and Skin Structure Infections caused by beta‑lactamase–producing isolates of Staphylococcus aureus, Escherichia coli, and Klebsiella species.
1.5 Urinary Tract Infections caused by beta‑lactamase–producing isolates of E.
coli, Klebsiella species, and Enterobacter species .
1.6 Limitations of Use When susceptibility test results show susceptibility to amoxicillin, indicating no beta-lactamase production, AUGMENTIN should not be used.
PEDIATRIC USE
8.4 Pediatric Use The safety and effectiveness of AUGMENTIN Powder for Oral Suspension and Chewable Tablets have been established in pediatric patients.
Use of AUGMENTIN in pediatric patients is supported by evidence from studies of AUGMENTIN Tablets in adults with additional data from a study of AUGMENTIN Powder for Oral Suspension in pediatric patients aged 2 months to 12 years with acute otitis media.
[see Clinical Studies (14.2 )] Because of incompletely developed renal function in neonates and young infants, the elimination of amoxicillin may be delayed; clavulanate elimination is unaltered in this age group.
Dosing of AUGMENTIN should be modified in pediatric patients aged <12 weeks (<3 months).
[see Dosage and Administration (2.2 ) ]
PREGNANCY
8.1 Pregnancy Teratogenic Effects :Pregnancy Category B.
Reproduction studies performed in pregnant rats and mice given AUGMENTIN (2:1 ratio formulation of amoxicillin:clavulanate) at oral doses up to 1200 mg/kg/day revealed no evidence of harm to the fetus due to AUGMENTIN.
The amoxicillin doses in rats and mice (based on body surface area) were approximately 4 and 2 times the maximum recommended adult human oral dose (875 mg every 12 hours).
For clavulanate, these dose multiples were approximately 9 and 4 times the maximum recommended adult human oral dose (125 mg every 8 hours).
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 needed.
NUSRING MOTHERS
8.3 Nursing Mothers Amoxicillin has been shown to be excreted in human milk.
Amoxicillin/clavulanate potassium use by nursing mothers may lead to sensitization of infants.
Caution should be exercised when amoxicillin/clavulanate potassium is administered to a nursing woman.
WARNING AND CAUTIONS
5 WARNINGS AND PRECAUTIONS Serious (including fatal) hypersensitivity reactions: Discontinue AUGMENTIN if a reaction occurs.
(5.1) Hepatic dysfunction and cholestatic jaundice: Discontinue if signs/symptoms of hepatitis occur.
Monitor liver function tests in patients with hepatic impairment.
(5.2) Clostridium difficile -associated diarrhea (CDAD): Evaluate patients if diarrhea occurs.
(5.3) Patients with mononucleosis who receive AUGMENTIN develop skin rash.
Avoid AUGMENTIN use in these patients.
(5.4) Overgrowth: The possibility of superinfections with fungal or bacterial pathogens should be considered during therapy.
(5.5) 5.1 Hypersensitivity Reactions Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta-lactam antibacterials, including AUGMENTIN.
These reactions are more likely to occur in individuals with a history of penicillin hypersensitivity and/or a history of sensitivity to multiple allergens.
Before initiating therapy with AUGMENTIN, careful inquiry should be made regarding previous hypersensitivity reactions to penicillins, cephalosporins, or other allergens.
If an allergic reaction occurs, AUGMENTIN should be discontinued and appropriate therapy instituted.
5.2 Hepatic Dysfunction Hepatic dysfunction, including hepatitis and cholestatic jaundice has been associated with the use of AUGMENTIN.
Hepatic toxicity is usually reversible; however, deaths have been reported.
Hepatic function should be monitored at regular intervals in patients with hepatic impairment.
5.3 Clostridium difficile Associated Diarrhea (CDAD) Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including AUGMENTIN, 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 antibacterial use.
Careful medical history is necessary since CDAD has been reported to occur over 2 months after the administration of antibacterial agents.
If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C.
difficile may need to be discontinued.
Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C.
difficile , and surgical evaluation should be instituted as clinically indicated.
5.4 Skin Rash in Patients with Mononucleosis A high percentage of patients with mononucleosis who receive amoxicillin develop an erythematous skin rash.
Thus, AUGMENTIN should not be administered to patients with mononucleosis.
5.5 Potential for Microbial Overgrowth The possibility of superinfections with fungal or bacterial pathogens should be considered during therapy.
If superinfection occurs, amoxicillin/clavulanate potassium should be discontinued and appropriate therapy instituted.
5.6 Phenylketonurics AUGMENTIN Chewable tablets and AUGMENTIN Powder for Oral Solution contain aspartame which contains phenylalanine.
Each 200-mg chewable tablet of AUGMENTIN contains 2.1 mg phenylalanine; each 400-mg chewable tablet contains 4.2 mg phenylalanine; each 5 mL of either the 200 mg/5 mL or 400 mg/5 mL oral suspension contains 7 mg phenylalanine.
The other formulations of AUGMENTIN do not contain phenylalanine.
5.7 Development of Drug-Resistant Bacteria Prescribing AUGMENTIN in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient, and increases the risk of the development of drug‑resistant bacteria.
INFORMATION FOR PATIENTS
17 PATIENT COUNSELING INFORMATION 17.1 Information for Patients Patients should be informed that AUGMENTIN may be taken every 8 hours or every 12 hours, depending on the dose prescribed.
Each dose should be taken with a meal or snack to reduce the possibility of gastrointestinal upset.
Patients should be counseled that antibacterial drugs, including AUGMENTIN, should only be used to treat bacterial infections.
They do not treat viral infections (e.g., the common cold).
When AUGMENTIN 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 AUGMENTIN or other antibacterial drugs in the future.
Counsel patients that diarrhea is a common problem caused by antibacterials, and it usually ends when the antibacterial is discontinued.
Sometimes after starting treatment with antibacterials, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken their last dose of the antibacterial.
If diarrhea is severe or lasts more than 2 or 3 days, patients should contact their physician.
Patients should be advised to keep suspension refrigerated.
Shake well before using.
When dosing a child with the suspension (liquid) of AUGMENTIN, use a dosing spoon or medicine dropper.
Be sure to rinse the spoon or dropper after each use.
Bottles of suspension of AUGMENTIN may contain more liquid than required.
Follow your doctor’s instructions about the amount to use and the days of treatment your child requires.
Discard any unused medicine.
Patients should be aware that AUGMENTIN contains a penicillin class drug product that can cause allergic reactions in some individuals.

(2.2) 2.1 Adults The usual adult dose is one 500-mg tablet of AUGMENTIN every 12 hours or one 250-mg tablet of AUGMENTIN every 8 hours.
For more severe infections and infections of the respiratory tract, the dose should be one 875-mg tablet of AUGMENTIN every 12 hours or one 500-mg tablet of AUGMENTIN every 8 hours.
Adults who have difficulty swallowing may be given the 125 mg/5 mL or 250 mg/5 mL suspension in place of the 500-mg tablet.
The 200 mg/5 mL suspension or the 400 mg/5 mL suspension may be used in place of the 875-mg tablet.
Two 250-mg tablets of AUGMENTIN should not be substituted for one 500-mg tablet of AUGMENTIN.
Since both the 250-mg and 500-mg tablets of AUGMENTIN contain the same amount of clavulanic acid (125 mg, as the potassium salt), two 250-mg tablets are not equivalent to one 500-mg tablet of AUGMENTIN.
The 250-mg tablet of AUGMENTIN and the 250-mg chewable tablet should not be substituted for each other, as they are not interchangeable.
The 250-mg tablet of AUGMENTIN and the 250-mg chewable tablet do not contain the same amount of clavulanic acid (as the potassium salt).
The 250-mg tablet of AUGMENTIN contains 125 mg of clavulanic acid, whereas the 250-mg chewable tablet contains 62.5 mg of clavulanic acid.
2.2 Pediatric Patients Based on the amoxicillin component, AUGMENTIN should be dosed as follows: Neonates and Infants Aged <12 weeks (<3 months) : The recommended dose of AUGMENTIN is 30 mg/kg/day divided every 12 hours, based on the amoxicillin component.
Experience with the 200 mg/5 mL formulation in this age group is limited, and thus, use of the 125 mg/5 mL oral suspension is recommended.
Patients Aged 12 weeks (3 months) and Older : See dosing regimens provided in Table 1.
The every 12 hour regimen is recommended as it is associated with significantly less diarrhea [see Clinical Studies (14.2)] .
However, the every 12 hour suspension (200 mg/5 mL and 400 mg/5 mL) and chewable tablets (200 mg and 400 mg) contain aspartame and should not be used by phenylketonurics.
[see Warnings and Precautions (5.6) ] Table 1: Dosing in Patients Aged 12 weeks (3 months) and Older INFECTION DOSING REGIMEN Every 12 hours Every 8 hours 200 mg/5 mL or 400 mg/5 mL oral suspension a 125 mg/5 mL or 250 mg/5 mL oral suspension a Otitis media b , sinusitis, lower respiratory tract infections, and more severe infections 45 mg/kg/day every 12 hours 40 mg/kg/day every 8 hours Less severe infections 25 mg/kg/day every 12 hours 20 mg/kg/day every 8 hours a Each strength of suspension of AUGMENTIN is available as a chewable tablet for use by older children.
b Duration of therapy studied and recommended for acute otitis media is 10 days.
Patients Weighing 40 kg or More : Pediatric patients weighing 40 kg or more should be dosed according to adult recommendations.
The 250-mg tablet of AUGMENTIN should not be used until the child weighs at least 40 kg,due to the different amoxicillin to clavulanic acid ratios in the 250-mg tablet of AUGMENTIN (250/125) versus the 250-mg chewable tablet of AUGMENTIN (250/62.5).
2.3 Patients with Renal Impairment Patients with impaired renal function do not generally require a reduction in dose unless the impairment is severe.
Renal impairment patients with a glomerular filtration rate of <30 mL/min should not receive the 875‑mg dose.
Patients with a glomerular filtration rate of 10 to 30 mL/min should receive 500 mg or 250 mg every 12 hours, depending on the severity of the infection.
Patients with a glomerular filtration rate less than 10 mL/min should receive 500 mg or 250 mg every 24 hours, depending on severity of the infection.
Hemodialysis patients should receive 500 mg or 250 mg every 24 hours,depending on severity of the infection.
They should receive an additional dose both during and at the end of dialysis.
