| Description | Cefmetazole is only found in individuals that have used or taken this drug. It is a semisynthetic cephamycin antibiotic with a broad spectrum of activity against both gram-positive and gram-negative microorganisms. It has a high rate of efficacy in many types of infection and to date no severe side effects have been noted. [PubChem]The bactericidal activity of cefmetazole results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). |
