Problems solved by technology

Traditional compound preparations are produced by mixing ceftriaxone sodium and tazobactam sodium aseptic powder and subpackaging. The clarity of the sterile product not only affects the solution clarity of the sterile product, but also further affects the clarity of the sterile product. content and the color grade of the solution
At the same time, due to the different specific volumes of the two sterile powders, the mixing uniformity is poor

Abstract

The invention discloses a production process of compound preparation of ceftriaxone sodium and tazobactam sodium for injection, comprising the steps of weighing raw materials of ceftriaxone sodium, tazobactam sodium, sterilized water for injection, mixed liquid of ethyl acetate and isopropanol, and anhydrous ethanol based on the weight ratio of 3-5:1:2:5:9; conducing dissolution and filtration; crystallizing and washing; and lyophilizing to obtain the compound preparation of ceftriaxone sodium and tazobactam sodium for injection. The invention is applicable to the compound preparation of ceftriaxone sodium and tazobactam sodium for injection, which is produced according to the ratio of 3:1-5:1 of ceftriaxone to tazobactam; and the invention adopts evenly mixing of liquid phase, can achieve good mixing uniformity, effectively increase the purity of the preparations simultaneously, and further guarantee the advantage of high safety of clinic use.

Description

technical field [0001] The invention relates to a production process of a compound preparation of ceftriaxone sodium and tazobactam sodium for injection. Background technique [0002] Ceftriaxone sodium is a third-generation cephalosporin with broad-spectrum antibacterial effects. With the widespread clinical application of cephalosporin antibiotics, bacteria undergo genetic mutations under the genetic pressure of antibiotics. Over the past two decades, the number of drug-resistant strains has increased, and the number of cases of severe and refractory infections, especially respiratory infections, is facing severe challenges of bacterial drug resistance clinically. At present, it has been developed for the production and use of compound preparations. In the second part of the "Pharmacopoeia of the People's Republic of China" in 2005, it is stipulated that ceftriaxone sodium and the like should be checked for "clarity and color of the solution". Therefore, it is an importan...
