 Use of Tazobactam


Tazobactam is a beta Lactamase Inhibitor with antibacterial activityTarget: AntibacterialTazobactam is a pharmaceutical drug that inhibits the action of bacterial β-lactamases, especially those belonging to the SHV-1 and TEM groups. It is commonly used as its sodium salt, Tazobactam sodium.Tazobactam is combined with the extended spectrum β-lactam antibiotic piperacillin in the drug piperacillin/Tazobactam, one of the preferred antibiotic treatments for nosocomial pneumonia caused by Pseudomonas aeruginosa. Tazobactam broadens the spectrum of piperacillin by making it effective against organisms that express β-lactamase and would normally degrade piperacillin. Tazobactam is derived from the penicillin nucleus and is a penicillinic acid sulfone.
