This invention discloses a cefoperazone sodium and sulbactam sodium composition and its preparation method, comprising the following steps: preparing a chitosan-β-glycerophosphate sodium colloidal solution; mixing dry ice and sorbitol evenly, then adding the mixture to the colloidal solution, freezing, heating, and drying under reduced pressure to obtain chitosan-β-glycerophosphate sodium nanospheres; slowly adding cefoperazone sodium, sulbactam sodium, and chitosan-β-glycerophosphate sodium nanospheres to water for injection, stirring to dissolve; adjusting the pH to 7.1-7.5, adding an adsorbent for adsorption and filtration, adding dry ice; freeze-drying to obtain a cefoperazone sodium and sulbactam sodium mixed powder. The nanospheres of this invention, with a certain size gradient, are beneficial for the uniformity of the mixed powder of cefoperazone sodium and sulbactam sodium, resulting in a longer-lasting efficacy, better stability, lower hygroscopicity, and also playing an antibacterial role.

This invention discloses a pharmaceutical composition containing cefoperazone sodium and tazobactam sodium for the treatment of renal insufficiency complicated with bacterial infection. The weight ratio of cefoperazone sodium to tazobactam sodium is 6:1. In the treatment of renal insufficiency complicated with bacterial infection, this composition effectively improves clinical efficacy while significantly reducing the incidence of adverse reactions, achieving a good balance between efficacy and safety. This invention also provides a pharmaceutical composition that effectively reduces the production of related substances, significantly improving the product quality of the 6:1 cefoperazone sodium and tazobactam sodium mixture, and further ensuring the stability of the drug during use, storage, and transportation.

The application provides a preparation method of cefoperazone, which comprises the following steps: providing a 7-TMCA solution; providing a HO-EPCP acyl chloride solution; adding the HO-EPCP acyl chloride solution into the 7-TMCA solution drop by drop under the condition of-30 to-20 DEG C, and continuing to react under the condition of-30 to-20 DEG C after the addition is completed to obtain a reaction solution containing cefoperazone. The preparation method of cefoperazone can effectively reduce the content of impurity H in cefoperazone. Experiments prove that the content of impurity H in cefoperazone can be reduced to less than 0.15%, the yield of cefoperazone reaches more than 90%, the purity of cefoperazone reaches more than 99.6%, and the content of other impurities is less than 0.15%, so that the cefoperazone prepared by the method can be used to prepare cefoperazone sodium which completely meets the quality standard of cefoperazone sodium raw medicine.
