Problems solved by technology

[0003] Because cefradine is a β-lactamase antibiotic, its chemical properties are unstable and easily hydrolyzed, seriously affecting product quality and even drug safety
At present, the marketed preparations are required to be stored in a cool and dark place to ensure the stability of the preparation, which has not fundamentally solved the problem of easy hydrolysis of cephradine

Abstract

The invention discloses a cefradine pharmaceutical composition, which is prepared from the following raw materials in parts by weight: 40 to 50 parts of cefradine, 10 to 20 parts of cyclodextrin, 10 to 20 parts of pregelatinized starch, 2 to 8 parts of sodium hydrogen carbonate, 0.5 to 1.1 parts of citric acid, 0.4 to 1 part of magnesium stearate, 2 to 8 parts of fatty acid sorbitan, 1 to 5 parts of lecithin, 2 to 6 parts of PVC (polyvinyl chloride) and 1 to 5 parts of aerosil. The cefradine pharmaceutical composition is simple and scientific in prescription and high in stability, and has little pharmacological toxic or side effects; in addition, a preparation process is simple and suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of medicine and chemical industry, in particular to a cefradine pharmaceutical composition. Background technique [0002] Cephalosporin antibiotics are semi-synthetic antibiotics made by concatenating the parent nucleus of 7-angicephalosporanic acid (7-ACA) of cephalosporins. This class of antibiotics has the advantages of broad antibacterial spectrum, strong bactericidal power, stability to gastric acid and β-lactamase, and less allergic reactions. Cefradine belongs to the first generation of cephalosporins, which is white or off-white crystalline powder, slightly odorous, slightly soluble in water, and almost insoluble in ethanol, chloroform and ether. [0003] Since cefradine is a β-lactamase antibiotic, its chemical properties are unstable and easily hydrolyzed, which seriously affects product quality and even drug safety. At present, the marketed preparations are required to be stored in a cool and dark place t...
