AUGMENTIN '500' vs AZLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin is a semisynthetic aminopenicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting cell wall integrity, leading to bacteriolysis. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to and inactivates a broad range of beta-lactamases, preventing degradation of amoxicillin and extending its spectrum to include beta-lactamase-producing bacteria.
Azlin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis.
1 tablet (amoxicillin 500 mg / clavulanate 125 mg) orally every 8 hours or 1 tablet (amoxicillin 875 mg / clavulanate 125 mg) orally every 12 hours for mild to moderate infections. For severe infections, use 875 mg/125 mg every 12 hours.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious infections.

Amoxicillin: 1-1.3 hours; clavulanate: 1 hour. In renal impairment (CrCl <30 mL/min): amoxicillin 7-20 hours, clavulanate 4-6 hours. Extends dosing interval.
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).
Renal excretion 50-70% (amoxicillin) and 40-60% (clavulanate) as unchanged drug; tubular secretion and glomerular filtration. Fecal elimination <10%.
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
