Problems solved by technology

[0013] The packed tower used in the existing solvent recovery technology in the pharmaceutical industry has low mass transfer efficiency, poor operational stability, low solvent content and high impurities, and thus cannot be directly applied to product reproduction, or the product produced after direct application has low purity, High impurities
Usually the recovered solvent needs to be further processed, which increases the production cost and increases the difficulty of the process

Abstract

The invention discloses a preparation method of a cefoperazone sodium and sulbactam sodium powder injection for injection. A recovered solvent is prepared by a stereo mass transfer tower plate technology, and is directly applied to production of cefoperazone sodium and sulbactam sodium products; the quality indexes such as color grade, clarity and purity of the obtained cefoperazone sodium and sulbactam sodium powder injection product for injection are greatly improved; the cefoperazone sodium and sulbactam sodium powder injection is high in quality stability and few in impurity; and the preparation method is low in production cost and simple in process.

Description

technical field [0001] This product relates to a preparation method of cefoperazone sodium sulbactam sodium powder preparation for injection, belonging to the technical field of medicine. Background technique [0002] Cefoperazone Sodium / Sulbactam Sodium for Injection is a broad-spectrum antibacterial drug composed of cefoperazone sodium (third-generation cephalosporin) and β-lactamase inhibitor sulbactam sodium with partial antibacterial activity. Bacteria and some anaerobic bacteria have antagonistic effects, especially for Gram-negative bacteria, and also have strong antagonistic effects for Pseudomonas aeruginosa. Wide range of clinical applications, mainly for the treatment of respiratory infections caused by sensitive bacteria, urinary tract infections, sepsis and burn infections and other diseases. [0003] Cefoperazone sodium is a third-generation cephalosporin with a molecular weight of 667.66 and a structural formula as follows: [0004] [0005] Its chemical ...
