AZLIN vs V-CILLIN
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.
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.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious infections.
250-500 mg orally every 8 hours or 500 mg every 12 hours for mild to moderate 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 ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
Primarily renal (60-70% unchanged via tubular secretion); minor biliary/fecal elimination (<10%).
