The present invention provides a composition for Ceftezole Sodium for Injection, involving drugs and drug manufacturing technology, contains the following ingredients: weight of Ceftezole sodium 7.26 ~ 9.17, 5.78 ~ 7.67 chitosan nanoparticles, 81.38 to 87.10 parts of water for injection. The advantages of the invention are: 1) a broader spectrum of antibacterial activity in vitro, improve anti pneumococcus, Pseudomonas aeruginosa, Acinetobacter bacilli and other characteristics of the single activity of Ceftezole sodium; 2) nanoparticles can change the membrane operating mechanism, increase the drug permeability of biological membranes, is conducive to the drugs in the cells; 3) nanoparticles wrapped along the vein of Ceftezole sodium quickly gathered in the main organs such as liver and spleen reticuloendothelial system, reduced due to non specific aggregation drugs toxicity; 4) chitosan nanoparticles can replace mannitol as lyophilized powder of lyophilized skeleton agent, eliminating the effects of mannitol on activity the human body.
