AUGMENTIN '875' vs AZLIN
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.
Azlin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis.
One 875 mg amoxicillin/125 mg clavulanate tablet orally every 12 hours.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious 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 is approximately 1.0–1.5 hours in adults with normal renal function; prolonged to 3–5 hours in moderate renal impairment (CrCl 10–50 mL/min) and up to 10 hours in severe renal impairment (CrCl <10 mL/min).
Amoxicillin: ~50-70% renal as unchanged drug, 10-20% biliary. Clavulanate: ~30-50% renal as unchanged, ~25% fecal.
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
