BEEPEN-VK vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
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 is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and activating autolytic enzymes.
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.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).

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 (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Primarily renal (70-80% as unchanged drug), with minor biliary/fecal excretion. Renal clearance is via tubular secretion and glomerular filtration.
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
