Aminoglycosides for the Treatment of Severe Infection Due to Resistant Gram-Negative Pathogens.

Aminoglycosides are a family of rapidly bactericidal antibiotics that often remain active against resistant Gram-negative bacterial infections. Over the past decade, their use in critically ill patients has been refined; however, due to their renal and cochleovestibular toxicity, their indications in the treatment of sepsis and septic shock have been gradually reduced. This article reviews the spectrum of activity, mode of action, and methods for optimizing the efficacy of aminoglycosides. We discuss the current indications for aminoglycosides, with an emphasis on multidrug-resistant Gram-negative bacteria, such as extended-spectrum β-lactamase-producing , carbapenemase-producing Enterobacterales, multidrug-resistant , and carbapenem-resistant . Additionally, we review the evidence for the use of nebulized aminoglycosides.
