Background:

Sulbactam(Betamaze) is an irreversible β-lactamase inhibitor.Target: β-lactamase; AntibacterialSulbactam is a mechanism-based inhibitor of beta-lactamase enzymes used in clinical practice. sulbactam was the antimicrobial agent responsible for the killing of these organisms [1]. sulbactam may prove effective for non-life-threatening A. baumannii infections. Its role in the treatment of severe infections is unknown. However, the current formulation of sulbactam alone may allow its use at higher doses and provide new potential synergic combinations, particularly for those infections by A. baumannii resistant to imipenem [2].
