General description

Chemical structure: ß-lactam

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.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
