Renal Dose

Administration

Tab: May be taken with or without food. Oral susp: Should be taken with food.

Contra Indications

Hypersensitivity to cephalosporins.

Precautions

Severe renal impairment; pregnancy, lactation; hypersensitivity to penicillins. Lactation: Drug excreted in breast milk; use with caution

Pregnancy-Lactation

Interactions

May enhance the nephrotoxic effect of strong-acting diuretics (e.g. furosemide) and aminoglycosides. May enhance the effect of oral anticoagulants. May reduce the efficacy of OCs. Probenecid prolongs the excretion of cefuroxime and elevated peak serum level.

Adverse Effects

Side effects of Cefuroxime + Clavulanic Acid : >10% Diarrhea (4-11%; depends on duration) 1-10% Decreased hemoglobin or hematocrit (10%), Eosinophilia (7%), Nausea or vomiting (3-7%), Vaginitis (<5%), Transient rise in hepatic transaminases (2-4%), Diaper rash (3%), Increase in alkaline phosphatase (2%), Thrombophlebitis (2%), Increase in lactate dehydrogenase (1%) <1% Anemia, Cholestasis, Colitis, Dyspnea, Epidermal necrolysis, Increase in blood urea nitrogen (BUN) and creatinine, Jaundice, Nephritis, Prolonged prothrombin time (PT)/international normalized ratio (INR), Rash, Stevens-Johnson syndrome, Stomach cramps, Transient neutropenia and leukopenia, Urticaria Potentially Fatal: Anaphylaxis, nephrotoxicity, pseudomembranous colitis.

Mechanism of Action

Cefuroxime binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death. Addition of clavulanate inhibits beta-lactamase-producing bacteria; Clavulanic acid has a high affinity for and binds to certain ?-lactamases that generally inactivate Cefuroxime by hydrolyzing its ?-lactam ring. Combining clavulanate potassium with Cefuroxime extends the antibacterial spectrum of Cefuroxime to include many bacteria normally resistant to Cefuroxime and other penicillins and cephalosporins.
