Abstract

The invention relates to a cefuroxime sodium raw material, an injection and a preparation method thereof, belonging to the technical field of medicine. The cefuroxime sodium raw material of the present invention is passed in a specific solvent environment, with a special dropping rate, dropwise adding cefuroxime acid solution and a 95% ethanol solution of sodium acetate trihydrate prepared according to a specific mixed solvent ratio and a specific concentration at the same time Prepared. The product quality and stability of cefuroxime sodium for injection prepared from this raw material through special process control has been significantly improved, especially the production of related substance 2 has been reduced, and the product quality has been strictly controlled, thereby ensuring the safety and effectiveness of the drug.

Description

technical field [0001] The invention relates to a cefuroxime sodium raw material, an injection and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Cefuroxime sodium was developed by the GlaxoSmithKline company of the United Kingdom, and was first listed in Germany, Ireland, the United Kingdom, and Italy (trade name Curoxim) in 1978. In 1980, it was launched in Japan by Shin Nihon Jitsugyo Company, under the trade name "Zinacef", only in oral dosage form. In October 1983, it was approved by the U.S. FDA by Teligent, and its trade name was Zinacef. The injection was launched in China in 1987 under the trade name Xilixin, and the tablet was launched in China in 1989. Cefuroxime sodium has been on the market at home and abroad for many years, and has been included in Chinese, British, American, and European pharmacopoeias, with clear safety and efficacy. [0003] Cefuroxime sodium is a second-generation cephalosporin, ...
