DURACILLIN A.S. vs VEETIDS '500'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G procaine is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
600,000 units intramuscularly once daily; or 1.2 million units intramuscularly every 12 hours for severe infections.
1 tablet (500 mg) orally twice daily for 7 days.

0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in end-stage renal disease
4-6 hours (prolonged in renal impairment; requires dose adjustment if CrCl <30 mL/min)
Primarily renal (60-90% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal elimination (<10%)
Renal: 60-80% unchanged; biliary/fecal: 15-25% as metabolites
