The role of sulbactam-durlobactam in treating carbapenem-resistant Acinetobacter infections

Purpose of review Infections caused by multidrug-resistant Acinetobacter baumannii present a significant global health challenge. Available treatment options are limited and frequently constrained by unfavourable safety and pharmacokinetic profiles. Sulbactam-durlobactam is a novel β-lactamase inhibitors combination specifically developed to target A. baumannii , including carbapenem-resistant strains. The purpose of this review is to assess the current evidence supporting the role of sulbactam-durlobactam in the management of A. baumannii infections. Recent findings We summarize the available evidence regarding the pharmacokinetic and pharmacodynamic profiles of sulbactam-durlobactam from key in-vitro and in-vivo studies. Additionally, efficacy results from the Phase III randomized controlled trial and real-world data on sulbactam-durlobactam's use against severe A. baumannii infections are also discussed. Summary Sulbactam-durlobactam is a promising addition to the treatment options for carbapenem-resistant A. baumannii infections. Ongoing research and vigilance are essential to monitor the development of in-vivo resistance, assess effectiveness across diverse patient populations, and explore potential synergistic combinations with other antimicrobials. Careful stewardship and comprehensive clinician education will be crucial to optimizing the clinical use of sulbactam-durlobactam.
