Problems solved by technology

[0013] 2. The stability of cephalosporin products in the solution is poor, and they should be used immediately after the solution is prepared. Due to the long dissolution time, the cefmenoxime will be degraded and the impurities will increase. Particles are easy to form embolism in the human body, leading to adverse reactions such as vasculitis, which seriously affects the safety and effectiveness of clinical medication, and brings inconvenience to clinical use

Embodiment 1

[0078] Cefmenoxime hydrochloride 1000g, sodium carbonate 533g, ethylenediamine 267g.

[0079] Preparation method: The cefmenoxime hydrochloride raw material is pulverized with a jet pulverizer using low-temperature inert gas (nitrogen) under sterile conditions. The pulverized cefmenoxime hydrochloride and auxiliary materials were mixed in a three-dimensional mixer for 30 minutes until uniformly mixed; the uniformly mixed aseptic mixed powder was packed in sterilized 20ml vials under aseptic conditions, and pressed Stoppering, capping, full inspection, packaging after passing the test, respectively to obtain 1000 bottles of powder injection.

Embodiment 2

[0081] Cefmenoxime hydrochloride 1000g, sodium carbonate 516g, ethylenediamine 284g.

[0082] Preparation method: The cefmenoxime hydrochloride raw material is pulverized with a jet pulverizer using low-temperature inert gas (nitrogen) under sterile conditions. The pulverized cefmenoxime hydrochloride and auxiliary materials were mixed in a three-dimensional mixer for 30 minutes until uniformly mixed; the uniformly mixed aseptic mixed powder was packed in sterilized 20ml vials under aseptic conditions, and pressed Stoppering, capping, full inspection, packaging after passing the test, respectively to obtain 1000 bottles of powder injection.

Embodiment 3

[0084] Cefmenoxime hydrochloride 1000g, sodium carbonate 485g, ethylenediamine 315g.

[0085] Preparation method: The cefmenoxime hydrochloride raw material is pulverized with a jet pulverizer using low-temperature inert gas (nitrogen) under sterile conditions. The pulverized cefmenoxime hydrochloride and auxiliary materials were mixed in a three-dimensional mixer for 30 minutes until uniformly mixed; the uniformly mixed aseptic mixed powder was packed in sterilized 20ml vials under aseptic conditions, and pressed Stoppering, capping, full inspection, packaging after passing the test, respectively to obtain 1000 bottles of powder injection.
