NCIt definition : The sodium salt form of tazobactam, a penicillanic acid sulfone derivative and beta-lactamase
inhibitor with antibacterial activity. Tazobactam contains a beta-lactam ring and
irreversibly binds to beta-lactamase at or near its active site. This protects other
beta-lactam antibiotics from beta-lactamase catalysis. This drug is used in conjunction
with beta-lactamase susceptible penicillins to treat infections caused by beta-lactamase
producing organisms.;
