| Application: | Cloxacillin is effective against infections caused by penicillin G-resistant staphylococci. It was used in studies of topical antibacterial agents for burn and crush wounds. |
| Biochem/physiol Actions: | Cloxacillin is a semi-synthetic antibiotic and a chlorinated derivative of oxacillin. It inhibits the last stage of bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Cloxacillin is often used as AmpC β-lactamase inhibitor in combination with β-lactam antibiotics. |
