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 protects piperacillin from degradation by bacterial beta-lactamase enzymes, extending its spectrum to include beta-lactamase-producing organisms. Together, they provide enhanced coverage against gram-positive, gram-negative, and anaerobic bacteria.
