Piperacillin Tazobactam 4.5gm Injection

Piperacillin Tazobactam 4.5gm Injection is a prescription broad-spectrum antibacterial medicine containing the combination of piperacillin and tazobactam. It is used to treat a range of serious bacterial infections, including certain intra-abdominal, skin and soft-tissue, respiratory, urinary tract, and other systemic infections caused by susceptible bacteria.

Piperacillin is an extended-spectrum penicillin antibiotic, while tazobactam is a beta-lactamase inhibitor that helps protect piperacillin from degradation by certain bacterial beta-lactamase enzymes.

How It Works

Piperacillin inhibits bacterial cell-wall synthesis, ultimately causing susceptible bacteria to die.

Tazobactam inhibits certain bacterial beta-lactamase enzymes that can otherwise break down piperacillin. By combining the two medicines, tazobactam extends the antibacterial activity of piperacillin against many beta-lactamase-producing bacteria.

• Intra-abdominal infections
