BEEPEN-VK vs V-CILLIN
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 (V-CILLIN) inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin activation, 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 8 hours or 500 mg every 12 hours for mild to moderate infections.

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).
Terminal elimination half-life ~30-60 minutes in normal renal function; prolonged in renal impairment (up to 10 hours in anuria).
Primarily renal (70-80% as unchanged drug), with minor biliary/fecal excretion. Renal clearance is via tubular secretion and glomerular filtration.
Primarily renal (60-70% unchanged via tubular secretion); minor biliary/fecal elimination (<10%).
