Abstract

The invention provides a cefoperazone sodium composition freeze-dried powder for injection, and belongs to the field of medicine and medicine preparation technology. The cefoperazone sodium composition freeze-dried powder comprises following raw material ingredients, by weight, 7.26 to 9.17 parts of cefoperazone sodium, 4.36 to 5.50 parts of chitosan nanoparticle, and 84.38 to 89.10 parts of injection water. Advantages of the cefoperazone sodium composition freeze-dried powder are that: 1) antibacterial activity of the cefoperazone sodium composition is increased significantly; 2) antibacterial spectrum is widened, and drug tolerance is reduced greatly; 3) improvement of activity is capable of shortening medication cycle of patients, and reducing occurrence likelihood of adverse reaction caused by accumulation of cefoperazone sodium; and 4) the chitosan nanoparticle can be used as a freeze-dried skeleton agent of the freeze-dried powder injection instead of mannitol, so that active effects of mannitol on human bodies are avoided.

Description

Technical field: [0001] The invention relates to the technical field of medicine and medicine manufacture, in particular to a cefoperazone sodium composition freeze-dried powder for injection. Background technique: [0002] Cefoperazone sodium is the third-generation broad-spectrum semi-synthetic cephalosporin, which can resist the degradation of various β-lactamases. It has a wide antibacterial spectrum and strong antibacterial effect. Unreasonable application causes bacteria to develop drug resistance, and drug-resistant strains gradually increase, which has become a major problem in clinical drug use. Its drug resistance is mainly due to the instability of cefoperazone sodium to hyperspectral lactamase produced by bacteria. [0003] Chitosan is an amino polysaccharide polymer obtained by deacetylating natural inactive chitin. The structure of chitosan is very similar to that of cellulose, except that the acetylamino group on the C2 sugar ring replaces the hydroxyl group...
