PEN-VEE K 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 the final transpeptidation step of 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 6-8 hours for mild to moderate infections; up to 2 g/day 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: 30-60 minutes in adults with normal renal function, prolonged to 3-10 hours in severe renal impairment.
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Renal excretion of unchanged drug via glomerular filtration and tubular secretion accounts for 60-90% of elimination; biliary/fecal elimination is minimal (<10%).
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
