How it Works (Mechanism of Action)

Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis. Sulbactam is a beta-lactamase inhibitor that protects cefoperazone from degradation by beta-lactamase enzymes produced by resistant bacteria, thereby extending its antibacterial spectrum. While the US FDA data states 'N/A' for mechanism, this is the established pharmacological action.
