AMPICILLIN TRIHYDRATE vs AUGMENTIN '200'
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), while clavulanate irreversibly inhibits beta-lactamases, preventing degradation 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 200 mg amoxicillin/28.5 mg clavulanate chewable tablet every 8 hours for mild to moderate infections; for severe infections, one 400 mg/57 mg tablet every 12 hours or one 200 mg/28.5 mg tablet every 8 hours.

Terminal elimination half-life 1-1.8 hours; prolonged in renal impairment (up to 10-20 hours in anuria)
Amoxicillin: ~1 hour in healthy adults, prolonged to 7-20 hours in renal impairment (CrCl <10 mL/min). Clavulanate: ~1 hour, similarly prolonged in renal impairment. The combination's half-life supports twice-daily dosing for most infections.
Renal: 75-90% unchanged; biliary: small amount; fecal: negligible
Amoxicillin: ~50-70% excreted unchanged in urine via glomerular filtration and tubular secretion, with the remainder hepatically metabolized and excreted in bile and feces. Clavulanate: ~30-50% excreted unchanged in urine, the rest metabolized and eliminated in bile and feces.
