Medical uses
The combination ampicillin/sulbactam (Unasyn) is available in the United States.[3]
The combination cefoperazone/sulbactam (Sulperazon) is available in many countries but not in the United States.[4]
The co-packaged combination sulbactam/durlobactam was approved for medical use in the United States in May 2023.[5]
Mechanism
Sulbactam is primarily used as a suicide inhibitor of β-lactamase, shielding more potent beta-lactams such as ampicillin.[6] Sulbactam itself contains a beta-lactam ring, and has weak antibacterial activity by inhibiting penicillin binding proteins (PBP) 1 and 3, but not 2.[7]
