Plazomicin Usage And Synthesis

Description

Plazomicin (PLZ) is a novel aminoglycoside approved by the U.S. Food and Drug Administration (FDA) for the treatment of complicated urinary tract infections (cUTI, including acute pyelonephritis) in adults due to multidrug-resistant carbapenem-resistant Enterobacterales (CRE) or extended-spectrum beta-lactamase (ESBL) producing bacteria. Despite the FDA Black Box Warning for aminoglycoside class effects, PLZ exhibited a favourable safety profile with decreased adverse effects in the largest in-human trials. In vitro, activity of PLZ, in comparison with that of other aminoglycosides, was found to be excellent, with 92.3% to 98.0% overall susceptibility in Enterobacterales, including CRE. Recently, PLZ was also shown to be active against certain multidrug-resistant (MDR) and extensively drug-resistant (XDR) Gram-negative pathogens for which limited treatment options are left[1-2].
