AMCILL vs CLOXAPEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
Oral: 250-500 mg every 6 hours. IV: 1-2 g every 4-6 hours.
