Tazobac® and beta-lactamase inhibitors


Tazobac® is often given in combination with other antibiotics.

Tazobaktam belongs to a group of beta-lactamase inhibitors (also called beta-lactamase inhibitors). Most of these drugs are given in a fixed combination because this is how they can work best. Tazobactam is given in combination with piperacillin and is available under the trade name Tazobac®.
Further combinations would be amoxicillin + clavulanic acid, ampicillin + sulbactam, sultamicillin + sulbactam.


All beta-lactamase inhibitors inhibit part of the bacterial enzyme beta-lactamase. This enzyme enables the bacteria to break down the beta-lactam ring of beta-lactam antibiotics (penicillin, Cephalosporin, Carbapenem) no longer inhibit. Thus the combination partners of the beta-lactamase inhibitors can work better.


The preparations are usually given in combination with each other, which makes the effect against bacteria more effective (Sulbactam + ampicillin, tazobactam + piperazillin, clavulanic acid + amoxycillin).
