CLOXAPEN vs PENICILLIN-2
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cloxapen inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBPs involved in the transpeptidation step of peptidoglycan cross-linking. It is resistant to staphylococcal beta-lactamases.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
Oral: 250-500 mg every 6 hours. IV: 1-2 g every 4-6 hours.
250 mg orally every 6 hours or 500 mg orally every 8 hours for mild to moderate infections; intravenous dosing: 1-2 million units every 4-6 hours.
