Faropenem, a highly efficacious and orally bioavailable beta-lactam antibiotic, exhibits an extensive range of in vitro antimicrobial activity against diverse gram-positive and -negative aerobes and anaerobes. Notably, Faropenem possesses inherent resistance to hydrolysis by virtually all beta-lactamases, including extended-spectrum beta-lactamases and AmpC beta-lactamases. Moreover, Faropenem has been developed as an oral prodrug, namely faropenem medoxomil, for the investigation of respiratory tract infections.
ARX-1796 (AV-006), an Avibactam prodrug, is an orally bioavailable β-lactamase inhibitor. Avibactam has a spectrum of inhibition of class A and C β-lactamases, including ESBLs, AmpC and Klebsiella pneumoniae carbapenemase (KPC) enzymes.
