Tazocin (Piperacillin-Tazobactam)

Tazocin is the brand name of the combination of piperacillin 2.5 g+ tazobactam 0.25g and it is available in the form of Powder for parenteral injection.This Combination does not increase the activity of piperacillin against pseudomonas.This is due to the fact that pseudomonas produce chromosomal beta lactamases, against which tazobactum is not effective .Antimicrobial spectrum of this combination seems to similar to that of ticarcillin and clavulanate combination.

Tazocin Uses

Tazocin is used to treat many different infections caused by bacteria, such as

  • Hospital accquired pneumonia,complicated intra abdominal infection, septicaemia (Blood Poisoning),
  • Complicated infection involving urinary tract infections and skin and soft tissue infections.
  • It is also used in infections in neutropenic patients (Low white Blood Count)

Mechanism Of Action

Tazocin Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin binding proteins (PBPs); that successively inhibits the ultimate transpeptidation step of peptidoglycan synthesis in bacterial cell walls, so inhibiting cell wall synthesis. bacteria eventually lyse as a result of ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) whereas cell wall assembly is arrested. Tazobactam inhibits several beta-lactamases, as well as staphylococcal penicillinase and richmond and Sykes types II, III, IV, and V, as well as extended spectrum enzymes; it’s only restricted activity against class I beta-lactamases other than class Ic types.
