Sulbactam is able to inhibit the most common forms of beta-lactamase but is not able to interact with the ampC cephalosporinase. Thus, it confers little protection against bacteria such as Pseudomonas aeruginosa, Citrobacter, Enterobacter, and Serratia, which often express this gene.
Cefoperazone, a bactericidal antibiotic, inhibits bacterial cell wall synthesis of actively dividing cells by binding to one or more penicillin binding proteins (PBPs). Sulbactam is a β-lactamase inhibitor and acts primarily by irreversible inactivation of β-lactamases.
