Curator's Comment: description was created based on several sources, including https://en.wikipedia.org/wiki/Sulbactam http://www.drugbank.ca/drugs/DB09324

Sulbactam is a β-lactamase inhibitor given in combination with β-lactam antibiotics to inhibit β-lactamase, an enzyme produced by bacteria that destroys the antibiotics. Sulbactam in combination with semisynthetic antibiotic ampicillin sodium is indicated for the treatment of infections due to susceptible strains of the designated microorganisms: Skin and Skin Structure Infections caused by beta-lactamase producing strains of Staphylococcus aureus, Escherichia coli etc; Intra-Abdominal Infections caused by beta-lactamase producing strains of Escherichia coli, Klebsiella spp. (including K. Pneumoniae) tec; Gynecological Infections caused by beta-lactamase producing strains of Escherichia coli, and Bacteroides spp. (including B. fragilis).
