AZLIN vs POLYCILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Azlin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis.
Polycillin (ampicillin) is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious infections.
250-500 mg orally every 6 hours or 500 mg intravenously every 4-6 hours for moderate to severe infections.

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).
Terminal elimination half-life is 0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in anuria.
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
Renal excretion of unchanged drug accounts for 60-80% via glomerular filtration and tubular secretion; 20-40% is hepatically metabolized and eliminated in bile/feces.
