Tazobactam is a β-lactamase inhibitor [1]. Tazobactam shows intrinsic activity against Acinetobacter strains.
The β-Lactamases are responsible for resistance to penicillins, extended-spectrum cephalosporins, monobactams, and carbapenems. In order to overcome β-lactamase-mediated resistance, β-lactamase inhibitors have been introduced into clinical practice [2].
Tazobactam alone showed an MIC of ≤ 8 mg/liter (range 2 to 32 mg/liter) against 29 of the 38 strains [1]. Tazobactam in combination with the ureidopenicillin, piperacillin successfully restored the activity of piperacillin against β-lactamase-producing bacteria [3]. Tazobactam exhibited inhibitory activity and protected piperacillin against Richmond and Sykes types II, III, IV and V β-lactamases, staphylococcal penicillinase and extended-spectrum β-lactamases [3]. Tazobactam showed species-specific activity against class I chromosomally-mediated enzymes [3].
Preliminary clinical data indicated that the fixed combination of piperacillin /tazobactam was effective in the treatment of moderate to severe polymicrobial infections, including skin, intra-abdominal and soft-tissue and lower respiratory tract infections [3]. Piperacillin/tazobactam in combination with an aminoglycoside was effective in the empirical treatment of fever in patients with neutropenia. In phase III trials, piperacillin/tazobactam showed a tolerability profile typical of a penicillin agent [3].
