PENICILLIN-VK vs PENTIDS '200'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin VK inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
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.
250-500 mg orally every 6-8 hours for mild to moderate infections; 500 mg orally every 6 hours for severe infections (e.g., streptococcal pharyngitis, skin infections).
Penicillin G benzathine: 1.2 million units intramuscularly as a single dose.

0.5 hours (normal renal function); prolonged to 3-10 hours in severe renal impairment (CrCl <10 mL/min).
0.5-1 hour; prolonged in renal impairment; anuric patients up to 10 hours
Renal: 20-40% unchanged via tubular secretion; hepatic metabolism to penicilloic acid; biliary/fecal: minimal (<5%).
Renal: 60-90% unchanged; biliary/fecal: 10-40%
