DURACILLIN A.S. vs VEETIDS '250'
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 '250' is an oral cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP-3, thereby disrupting peptidoglycan cross-linking and leading to cell lysis.
600,000 units intramuscularly once daily; or 1.2 million units intramuscularly every 12 hours for severe infections.
250 mg orally every 8 hours for 7-10 days
