Piperacillin penicillin resistance. Medical search. Frequent questions

Piperacillin is most commonly used in combination with the beta-lactamase inhibitor tazobactam (piperacillin/tazobactam), which enhances piperacillin's effectiveness by inhibiting many beta lactamases to which it is susceptible. (wikipedia.org)
However, the co-administration of tazobactam does not confer activity against MRSA, as penicillin (and most other beta lactams) do not avidly bind to the penicillin-binding proteins of this pathogen. (wikipedia.org)

The options of empirical antimicrobial agents in clinical practice mainly depend on the causative organisms and their antimicrobial resistance (AMR) patterns. (biomedcentral.com)
