PENICILLIN G POTASSIUM IN PLASTIC CONTAINER vs VEETIDS '500'
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 '500' (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis. It has activity against both gram-positive and gram-negative bacteria.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
1 tablet (500 mg) orally twice daily for 7 days.

0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
4-6 hours (prolonged in renal impairment; requires dose adjustment if CrCl <30 mL/min)
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
Renal: 60-80% unchanged; biliary/fecal: 15-25% as metabolites
