AZLIN vs POLYCILLIN-N
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.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, and activating autolytic enzymes. It is bactericidal against susceptible organisms.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious infections.
1-2 g IV/IM every 4-6 hours

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: 0.5-1 hour (normal renal function); increases to 7-10 hours in anuria. Prolonged in neonates (2-4 hours).
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
Renal: 60-80% unchanged via glomerular filtration and tubular secretion. Biliary: ~20% excreted in bile and feces. Small amount metabolized to penicilloic acid.
