Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). Clavulanate is a beta-lactamase inhibitor that irreversibly binds to and inactivates beta-lactamase enzymes, preventing degradation of amoxicillin.
Bactericidal: inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation. Active against gram-positive bacteria and some gram-negative bacteria.
One 875 mg amoxicillin/125 mg clavulanate tablet orally every 12 hours.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours.

Amoxicillin: 1-1.5 hours (may extend to 7-13 hours in renal impairment). Clavulanate: ~1 hour (may extend to 2.5-4.5 hours in renal impairment).
Terminal elimination half-life: 1.0-1.5 hours in normal renal function. Extended to 2-6 hours in renal impairment; requires dose adjustment when CrCl <30 mL/min.
Amoxicillin: ~50-70% renal as unchanged drug, 10-20% biliary. Clavulanate: ~30-50% renal as unchanged, ~25% fecal.
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <5% as unchanged drug and metabolites.
