Piperacillin Sodium I.P. 4000 mg + Tazobactam Sodium I.P. 500 mg is a prescription antibiotic combination containing piperacillin and tazobactam. It is used for the treatment of certain serious bacterial infections caused by susceptible microorganisms and is generally administered under medical supervision.
Piperacillin is a penicillin-class antibiotic that works by interfering with bacterial cell-wall formation, while tazobactam helps protect piperacillin from degradation by certain bacterial beta-lactamase enzymes. This combination provides broad-spectrum antibacterial activity and may be used for infections involving the respiratory tract, urinary tract, abdomen, skin, and other sites when clinically appropriate.
