BETAPEN-VK vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin V binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting peptidoglycan synthesis, leading to cell lysis.
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; up to 500 mg orally every 4 hours for severe infections.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).

0.5-1 hour in patients with normal renal function; prolonged to 7-10 hours with creatinine clearance <10 mL/min.
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Renal excretion accounts for 20-40% of the dose as unchanged drug via tubular secretion and glomerular filtration; biliary/fecal excretion is minimal (<10%).
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
