AMCILL vs AMOXICILLIN AND CLAVULANATE POTASSIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins. Clavulanate potassium is a beta-lactamase inhibitor that irreversibly inactivates beta-lactamase enzymes, preventing degradation of amoxicillin.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
500 mg amoxicillin/125 mg clavulanate orally every 8 hours or 875 mg amoxicillin/125 mg clavulanate orally every 12 hours. For severe infections: 875 mg amoxicillin/125 mg clavulanate orally every 8 hours or 1000 mg amoxicillin/62.5 mg clavulanate extended-release orally every 12 hours.

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
Amoxicillin: ~1-1.5 hours; Clavulanate: ~1 hour. Prolonged in renal impairment.
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Renal: ~50-70% amoxicillin unchanged; ~25-40% clavulanate as metabolites. Fecal: minimal. Biliary: minor.
