Sulbactam Sodium

**Semantic type:** Pharmacologic Substance

**Definition:** The sodium salt form of sulbactam, a beta-lactam with weak antibacterial property. Sulbactam sodium contains a beta-lactam ring and irreversibly binds to beta-lactamase at or near its active site, thereby blocking enzyme activity and preventing metabolism of other beta-lactam antibiotics. Combining this agent with a beta-lactamase sensitive antibiotic such as penicillins and cephalosporins against penicillinase-producing and beta-lactamase-producing organisms, results in a decreased turnover rate of the sensitive antibiotic and enhances its antibacterial property.

**Synonyms:** - 4-Thia-1-azabicyclo(3.2.0)heptane-2-carboxylic Acid, 3,3-dimethyl-7-oxo-, 4,4-dioxide, Sodium Salt,(2S-cis)- - Penicillanic Acid 1,1-dioxide, Sodium Salt - SULBACTAM SODIUM - Sodium(2S,5R)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylate 4,4-Dioxide
