Dược Lực Học :
Cefotiam is a third generation beta-lactam cephalosporin antibiotic. It has broad spectrum activity against Gram positive and Gram negative bacteria. It does not have activity against Pseudomonas aeruginosa. Cefotiam works by inhibiting bacterial cell wall biosynthesis.
Cơ Chế Tác Dụng :
One of the cephalosporins that has a broad spectrum of activity against both gram-positive and gram-negative microorganisms. [PubChem]
The bactericidal activity of cefotiam results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).
