It is of paramount importance to understand this medication and its updates regarding its clinical use to inform precise therapeutic choices aimed at optimizing patient care. Objective: To describe the main pharmacological and therapeutic aspects of piperacillin-tazobactam, highlighting its clinical application and updates related to its use. Methods: A narrative review of the literature was conducted to provide an update on the most relevant aspects related to piperacillin-tazobactam, including (1) a brief history; (2) chemical structure; (3) mechanism of action; (4) resistance mechanisms; (5) spectrum; (6) major clinical uses; and (7) adverse effects. Results: The safe use of piperacillin-tazobactam necessitates rapid testing for antimicrobial resistance patterns, discouraging its empirical use in cases of ESBL-producing microorganisms. In patients undergoing renal replacement therapy, it is crucial to establish antibiotic goals promptly. For critically ill patients, monitoring pharmacodynamic and pharmacokinetic variability is essential. Conclusion: Piperacillin-tazobactam remains a vital drug in the management of critically ill patients, requiring constant updates. Furthermore, there is a need for further studies, especially concerning its continuous use and the selection of alternatives to carbapenem-resistant medications.</p> ER -
