BEEPEN-VK vs PENBRITIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin V potassium is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This disrupts the cross-linking of peptidoglycan chains, leading to cell lysis and death. It is bactericidal against susceptible organisms.
Penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and preventing peptidoglycan cross-linking, leading to cell lysis.
250-500 mg orally every 6 hours for mild to moderate infections; 500 mg orally every 6 hours for severe infections; maximum 4 g/day.
250-500 mg orally every 6 hours; 500 mg to 2 g intramuscularly or intravenously every 4-6 hours.

Terminal elimination half-life is 0.7-1.4 hours in patients with normal renal function; prolonged to 3-20 hours in severe renal impairment (CrCl <10 mL/min).
0.5-1 hour in normal renal function; extended to 2-6 hours in renal impairment. Hemodialysis shortens half-life.
Primarily renal (70-80% as unchanged drug), with minor biliary/fecal excretion. Renal clearance is via tubular secretion and glomerular filtration.
Renal: ~75-90% unchanged via glomerular filtration and tubular secretion. Biliary: ~10% in feces. Minor hepatic metabolism to penicilloic acid.
