Description:
Relebactam is a diazabicyclooctane inhibitor with activity against a wide spectrum of β-lactamases, including class A (extended-spectrum β-lactamases [ESBLs] and KPC) and class C (AmpC) enzymes. Target: beta-lactamase Imipenem with Relebactam is active against Escherichia coli, Klebsiella pneumoniae, and Enterobacter spp., including K. pneumoniae carbapenemase (KPC)-producing isolates. The combination of Imipenem with Relebactam demonstrated activity against KPC-producing Enterobacteriaceae and multidrug-resistant P. aeruginosa. The imipenem MIC50 and MIC90 values for the ESBL-producing isolates were 0.25 and 0.5 μg/ml, respectively; with the addition of Relebactam, the corresponding values were 0.25 and 0.25 μg/ml. Five isolates harbored blaKPC. For these 5 isolates, the imipenem MICs ranged from 0.5 to >32 μg/ml. With the addition of Relebactam, the MICs decreased to
0.12 to 0.5 μg/ml.[1] Relebactam inhibits most class A and class C β-lactamases, with selected inhibition of class D enzymes by avibactam. β-Lactamase inhibitors (BLIs) have played an important role in combatting β-lactam resistance in Gram-negative bacteria, but their effectiveness has diminished with the evolution of
diverse and deleterious varieties of β-lactamases.
