Dược Lực Học : Cefmetazole is a second-generation cephalosporin. The cephalosporins are bactericidal drugs with both gram-positive and gram-negative activity. They inhibit bacterial cell wall synthesis in a way similar to the penicillins. Cefmetazole is more active than 1st-generation cephalosporins against indole-positive Proteus, Serratia, anaerobic gram-negative bacilli (including B. fragilis), and some E. coli, Klebsiella, and P. mirabilis, but is less active than cefoxitin or cefotetan against most gram-negative bacilli.
Cơ Chế Tác Dụng : 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).
