AUGMENTIN '875' vs V-CILLIN
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 G (V-CILLIN) inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin activation, leading to cell lysis.
One 875 mg amoxicillin/125 mg clavulanate tablet orally every 12 hours.
250-500 mg orally every 8 hours or 500 mg every 12 hours for mild to moderate 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).
Terminal elimination half-life ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
Amoxicillin: ~50-70% renal as unchanged drug, 10-20% biliary. Clavulanate: ~30-50% renal as unchanged, ~25% fecal.
Primarily renal (60-70% unchanged via tubular secretion); minor biliary/fecal elimination (<10%).
