It was patented in 1977 and approved for medical use in 1986.
Sulbactam is able to inhibit the most common forms of β-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 is combined to form 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.
Sulbactam is partially irreversible inhibitor of β-lactamase; it binds with Beta Lactamases while some part of it again get released making it reversible in nature.
- Sultamicillin, an ester of sulbactam with the penicillin antibiotic ampicillin
- Other betalactamase inhibitors
