Mechanism Of Action This drug is an oral antibacterial combination consisting of amoxicillin and the beta lactamase inhibitor, clavulanate potassium (the potassium salt of clavulanic acid). Amoxicillin is a semisynthetic antibiotic with in vitro bactericidal activity against Gram-positive and Gram-negative bacteria. Clavulanic acid is a beta-lactam, structurally related to the penicillins, which possesses the ability to inactivate some beta-lactamase enzymes commonly found in microorganisms resistant to penicillins and cephalosporins
INDICATIONS It is indicated in the treatment of infections due to susceptible isolates of the designated bacteria in these conditions: • Lower Respiratory Tract Infections: Caused by beta lactamase–producing isolates of Haemophilus influenzae and Moraxella catarrhalis. • Acute Bacterial Otitis Media: Caused by beta lactamase–producing isolates of H. influenzae and M. catarrhalis. • Sinusitis: Caused by beta lactamase–producing isolates of H. influenzae and M. catarrhalis. • Skin and Skin Structure Infections: Caused by beta lactamase–producing isolates of Staphylococcus aureus, Escherichia coli, and Klebsiella species. • Urinary Tract Infections: Caused by beta lactamase–producing isolates of E. coli, Klebsiella species, and Enterobacter species.
CONTRAINDICATIONS • In patients with a history of serious hypersensitivity reactions (e.g., anaphylaxis or Stevens - Johnson syndrome) to amoxicillin, clavulanate or to other beta lactam antibacterial drugs (e.g., penicillins and cephalosporins). • In patients with a previous history of cholestatic jaundice/hepatic dysfunction associated with this drug.
Side EFFECTS the higher recommended dose. Other less frequently reported adverse reactions (<1%) include: Abdominal discomfort, flatulence, and headache. Overall, the adverse reactions in pediatric patient seen were comparable to that noted above; However, there were differences in the rates of diarrhea, skin rashes/urticaria, and diaper area rash. Postmarketing Experience: Gastrointestinal: Indigestion, gastritis, stomatitis, glossitis, black “hairy” tongue, mucocutaneous candidiasis, enterocolitis, and hemorrhagic/pseudomembranous colitis. Liver: Hepatic dysfunction, including hepatitis and cholestatic jaundice, increases in serum transaminases (AST and/or ALT), serum bilirubin, and/or alkaline phosphatase, has been reported with this drug. It has been reported more commonly in the elderly, in males, or in patients on prolonged treatment. The onset of signs/symptoms of hepatic dysfunction may occur during or several weeks after therapy has been discontinued. The hepatic dysfunction, which may be severe, is usually reversible. Deaths have been reported. Renal: Interstitial nephritis, hematuria, and crystalluria have been reported. Hemic and Lymphatic Systems: Anemia, including hemolytic anemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia, and agranulocytosis has been reported. These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena. Central Nervous System: Agitation, anxiety, behavioral changes, confusion, convulsions, dizziness, insomnia and reversible hyperactivity have been reported. Miscellaneous: Tooth discoloration (brown, yellow, or gray staining) has been reported. Most reports occurred in pediatric patients. Discoloration was reduced or eliminated with brushing or dental cleaning in most cases
WARNINGS • Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta-lactam antibacterials, including this drug. 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, careful inquiry should be made regarding previous hypersensitivity reactions to penicillins, cephalosporins, or other allergens. If an allergic reaction occurs, it should be discontinued and appropriate therapy instituted. • Hepatic dysfunction, including hepatitis and cholestatic jaundice has been associated with the use of this drug. Hepatic toxicity is usually reversible; however, deaths have been reported. Hepatic function should be monitored at regular intervals in patients with hepatic impairment. • Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including this drug, 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. 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. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against C. difficile colitis. • A high percentage of patients with mononucleosis who receive amoxicillin develop an erythematous skin rash. Thus, it should not be administered to these patients. • The possibility of superinfections with fungal or bacterial pathogens should be considered during therapy. If superinfection occurs, the drug should be discontinued and appropriate therapy instituted. • The chewable tablets and the Powder for Oral suspension should not be taken by patients with Phenylketonuria because both contain aspartame which contains phenylalanine Pediatric Use: The safety and effectiveness of the Powder for Oral Suspension and chewable tablets have been established in pediatric patients. 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 this drug should be modified in pediatric patients aged <12 weeks (<3 months). Geriatric Use: No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out. 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. Information For Patients • Patients should be counseled that antibacterial drugs, including this drug, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). • 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: decrease the effectiveness of the treatment, and increase the likelihood that bacteria will develop resistance and will not be treatable by this drug or other antibacterial drugs in the future. • Patients should be counseled that diarrhea is a common problem caused by anti-bacterials, and it usually ends when the antibacterial is discontinued. Sometimes after starting treatment with anti-bacterials, patients can develop watery and bloody stools 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 the physician.
DRUG INTERACTIONS Probenecid: Probenecid decreases the renal tubular secretion of amoxicillin but does not delay renal excretion of clavulanic acid. Concurrent use may result in increased and prolonged blood concentrations of amoxicillin. Coadministration of probenecid is not recommended. Oral Anticoagulants: Abnormal prolongation of prothrombin time (increased [INR]) has been reported in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken when anticoagulants are prescribed concurrently with this drug. Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation. 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. Oral Contraceptives: This drug may affect intestinal flora, leading to lower estrogen reabsorption and reduced efficacy of combined oral estrogen/progesterone contraceptives. 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 this drug, it is recommended that glucose tests based on enzymatic glucose oxidase reactions be used.
Pregnancy And lactations There are no adequate and well controlled studies in pregnant women; therefore it should be used during pregnancy only if clearly needed. Nursing Mothers: Amoxicillin has been shown to be excreted in human milk. Use of this drug by nursing mothers may lead to sensitization of infants. Caution should be exercised when it is administered to a nursing woman.
OVERDOSE In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures as required. Interstitial nephritis resulting in oliguric renal failure has been reported in patients after overdosage with this drug. Crystalluria, in some cases leading to renal failure, has also been reported after 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.
