Uses
Tazobactam acid (CAS NO.89786-04-9) 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.In the United States, sulbactam(89786-04-9) is combined to form cefoperazone/sulbactam and ampicillin/sulbactam. It does possess some antibacterial activity when administered alone, but it is too weak to have any clinical importance. Its use in the UK is restricted to hospitals.
