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.
Similar to penicillins and cephalosporins, carbapenems are members of the beta-lactam antibiotics drug class, which kill bacteria by binding to penicillin-binding proteins, thus inhibiting bacterial cell wall synthesis. However, these agents individually exhibit a broader spectrum of activity compared to most cephalosporins and penicillins.
Currently available beta-lactamase inhibitors are effective against Ambler Class A beta-lactamases (tazobactam, clavulanate, and sulbactam) or against Ambler Class A, C and some Class D beta-lactamases (avibactam). Like beta-lactam antibiotics, they are processed by beta-lactamases to form an initial covalent intermediate.
Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class. [1] The chemical structure of piperacillin and other ureidopenicillins incorporates a polar side chain that enhances penetration into Gram-negative bacteria and reduces susceptibility to cleavage by Gram-negative beta lactamase enzymes.
[18] [19] Tazobactam is partially metabolized to an inactive metabolite, and both drug and metabolite are excreted in the urine (80% as unchanged drug). [ 20 ] The half-life of ceftolozane is 2.5–3.0 hours, and the half-life of tazobactam is approximately 1.0 hour; the clearance of both drugs is directly proportional to renal function.
This drug is given in combination with β-lactam antibiotics to inhibit β-lactamase, an enzyme produced by bacteria that destroys the antibiotics. [1] It was patented in 1977 and approved for medical use in 1986. [2]
