BACTOCILL vs BEEPEN-VK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BACTOCILL (nafcillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibitors. Active against Staphylococcus aureus and other gram-positive bacteria.
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.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours
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.

0.5-0.8 hours; prolonged to 2-4 hours in severe renal impairment
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).
Renal: 60-70% unchanged; biliary: 20-30% as active metabolite; fecal: 5-10%
Primarily renal (70-80% as unchanged drug), with minor biliary/fecal excretion. Renal clearance is via tubular secretion and glomerular filtration.
