PENTIDS '200' vs VERSAPEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and activating autolytic enzymes.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.
500 mg IV every 6 hours or 1 g IV every 8 hours for moderate infections; 2 g IV every 4 hours for severe infections.

0.5-1 hour; prolonged in renal impairment; anuric patients up to 10 hours
0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in anuria. Requires dose adjustment in renal impairment.
Renal: 60-90% unchanged; biliary/fecal: 10-40%
Renal: 60-70% unchanged via glomerular filtration and tubular secretion. Biliary: <10% excreted unchanged. Fecal: 20-30% as metabolites.
