LEDERCILLIN VK vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin V is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It is bactericidal against susceptible organisms during the active growth phase.
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.
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 0.5 hours (range 0.4–0.6 hours) in adults with normal renal function. In severe renal impairment (CrCl <10 mL/min), half-life extends to ~4 hours.
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Renal elimination predominantly via tubular secretion of unchanged drug (>90% of absorbed dose). Approximately 20-40% of an oral dose is recovered in urine as unchanged penicillin V. Biliary excretion accounts for <1% of elimination; fecal elimination is negligible.
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
