应用

Cefotiam dihydrochloride hydrate is used as broad-spectrum antibiotic.

生化/生理作用

Cefotiam is a second generation cephalosporin antibiotic which has been used as a prophylatic antibiotic for MRSA.
Cefotiam, a derivative of cephalosporin, exhibits broad-spectrum anti-bacterial activity. It inhibits the cross-linking stage of peptidoglycan and blocks the synthesis of bacterial cell wall. It is resistant to β-lactamases.
