Tazobactam 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. In simple terms, it is an ingredient that can be added to certain antibiotics to make them less vulnerable to bacteria's antimicrobial resistance.
Tazobactam is combined with the extended spectrum β-lactam antibiotic piperacillin in the drug piperacillin/tazobactam, used in infections due Pseudomonas aeruginosa. Tazobactam broadens the spectrum of piperacillin by making it effective against organisms that express β-lactamase and would normally degrade piperacillin.
