NCIt definition : 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.;
