Cefmenoxime hydrochloride

A semisynthetic, broad-spectrum third-generation cephalosporin antibiotic used to treat susceptible bacterial infections, including respiratory tract, urinary tract, and other serious infections. Cefmenoxime binds to bacterial penicillin-binding proteins and inhibits the final stages of peptidoglycan biosynthesis, leading to bacterial cell lysis. It exhibits activity against a range of Gram-positive and Gram-negative bacteria and is administered parenterally
