PENICILLIN G POTASSIUM IN PLASTIC CONTAINER 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), inhibiting transpeptidation and activating autolytic enzymes.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
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 (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
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 via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
Renal: 60-70% unchanged via glomerular filtration and tubular secretion. Biliary: <10% excreted unchanged. Fecal: 20-30% as metabolites.
