Mechanism of action

Ceftazidime is a third-generation cephalosporin that inhibits bacterial cell wall cross-linking. Avibactam is a non-beta-lactam beta-lactamase inhibitor that protects ceftazidime from degradation by serine beta-lactamases. Sulbactam is an additional beta-lactamase inhibitor that provides broader coverage against resistant gram-negative organisms, particularly Acinetobacter baumannii.
