Mechanism of Action
Piperacillin has an antimicrobial activity against a wide range of gm-ve organisms including K. pneumoniae, P. aeruginosa, Enterobacteriaceae and against gm+ve organisms eg E. faecalis and B. fragilis. Tazobactam is a penicillanic acid sulfone derivative with beta-lactamase inhibitory properties. In combination, tazobactam enhances the activity of piperacillin against beta-lactamase-producing bacteria.
