AUGMENTIN '875' vs VERSAPEN
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 peptidoglycan cross-linking.
One 875 mg amoxicillin/125 mg clavulanate tablet orally every 12 hours.
500 mg IV every 6 hours or 1 g IV every 8 hours for moderate infections; 2 g IV every 4 hours for severe infections.

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).
0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in anuria. Requires dose adjustment in renal impairment.
Amoxicillin: ~50-70% renal as unchanged drug, 10-20% biliary. Clavulanate: ~30-50% renal as unchanged, ~25% fecal.
Renal: 60-70% unchanged via glomerular filtration and tubular secretion. Biliary: <10% excreted unchanged. Fecal: 20-30% as metabolites.
