Mechanism of action

Piperacillin is a broad-spectrum beta-lactam antibiotic that binds to penicillin-binding proteins and disrupts bacterial cell wall cross-linking. Tazobactam is a beta-lactamase inhibitor that irreversibly binds and inactivates beta-lactamase enzymes produced by resistant bacteria, preventing degradation of piperacillin and extending its spectrum of activity against otherwise resistant gram-negative and gram-positive organisms.
