AMPICILLIN TRIHYDRATE vs AUGMENTIN '250'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activity.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to beta-lactamases, preventing hydrolysis of amoxicillin.
250-500 mg PO q6h or 1-2 g IV/IM q4-6h; up to 12 g/day IV for severe infections.
One 250 mg amoxicillin/125 mg clavulanate tablet orally every 8 hours for 7-10 days.

Terminal elimination half-life 1-1.8 hours; prolonged in renal impairment (up to 10-20 hours in anuria)
Amoxicillin: 1.0-1.3 hours; clavulanate: 1.0-1.5 hours; prolonged in renal impairment (up to 7 hours for amoxicillin in anuria).
Renal: 75-90% unchanged; biliary: small amount; fecal: negligible
Renal: ~50-70% as amoxicillin, ~25-40% as clavulanate unchanged; biliary/fecal: minor (10-15% combined).
