描述

一般說明

Potent β-lactamase-resistant antibiotic of cephalosporin class. Active against gram-positive and gram-negative organisms, including gram-negative anaerobes. Inhibits cell wall synthesis. Has an optimal pH of 4.5-6.5.

生化／生理作用

Mode of Action: Inhibits bacterial cell wall synthesis.

Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.

其他說明

Broad spectrum third generation cephalosporin antibiotic.
