Piperacillin Sodium + Tazobactum

AUXITAZ is an injectable combination of two antibiotics, piperacillin and tazobactam, with broad spectrum activity against an extended range of bacterial species. Piperacillin is an extended-spectrum penicillin antibiotic, but it can be destroyed by an enzyme produced by bacteria called beta lactamase. Tazobactam inhibits beta lactamase and prevents the destruction of piperacillin. Therefore, tazobactam is given with piperacillin to enhance the activity of piperacillin in eradicating bacterial infections. In-vitro studies of piperacillin and tazobactam have shown that the combination has activity against a variety of gram-positive and gram-negative aerobic and anaerobic bacteria.

Piperacillin Sodium 4gm + Tazobactum 500mg


Piperacillin kills bacteria by inhibiting the synthesis of bacterial cell walls. It binds preferentially to specific penicillin-binding proteins (PBPs) located inside bacterial cell walls.

Tazobactam broadens the spectrum of piperacillin by making them effective against organisms that express beta-lactamase and would normally degrade them. This occurs through the irreversible inhibition of beta-lactamase enzymes. In addition, tazobactam may bind covalently to plasmid-mediated and chromosome-mediated beta-lactamase enzymes. Tazobactam is predominantly effective against the OHIO-1, SHV-1, and TEM groups of beta-lactamases, but may also inhibit other beta-lactamases.
