OXACILLIN SODIUM vs PENTIDS '800'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxacillin is a penicillinase-resistant beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking the transpeptidation step in peptidoglycan cross-linking. It is resistant to staphylococcal beta-lactamase.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), transpeptidases that catalyze the final transpeptidation step of peptidoglycan cross-linking, leading to cell lysis.
