Mode 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.

Precaution

Pregnancy and lactation, pseudomembranous colitis. Assess hematopoietic function periodically. Perform periodic electrolyte determinations in patients with low K reserves. Increased risk of fever and rash in patients with cystic fibrosis. Increased risk of bleeding manifestations. Prolonged treatment may increase risk of superinfections. Convulsions or neuromuscular excitability may occur when high doses are used, especially in renally impaired patients. Renal impairment. Lactation: Low concentrations of piperacillin excreted in breast milk; tazobactam unknown; use caution
