AUGMENTIN '875' vs V-CILLIN K
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.
Penicillin V exerts bactericidal activity by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
One 875 mg amoxicillin/125 mg clavulanate tablet orally every 12 hours.
250-500 mg orally every 6 hours for mild to moderate infections; 500 mg orally every 6 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 hour (normal renal function); prolonged to 2–6 hours in renal impairment.
Amoxicillin: ~50-70% renal as unchanged drug, 10-20% biliary. Clavulanate: ~30-50% renal as unchanged, ~25% fecal.
Renal: 60-90% unchanged via tubular secretion and glomerular filtration; minor biliary/fecal: <10%.
