PENICILLIN G POTASSIUM IN PLASTIC CONTAINER vs VEETIDS '125'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VEETIDS '125' (presumed to be a formulation containing penicillin V potassium) inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
125 mg orally twice daily for 5-10 days.

0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
2-4 hours in patients with normal renal function (CrCl >80 mL/min); prolonged to 20-40 hours in anuria. Clinical note: dosing interval must be adjusted based on creatinine clearance to avoid accumulation.
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; biliary/fecal <5%.
