Abstract

The invention discloses a preparation method and a detection method for ceftizoxime sodium. Various factors which influence the quality and yield of the product in the process of producing the ceftizoxime sodium are subjected to experimental analysis and research, and optimal process conditions for producing the ceftizoxime sodium are obtained; and a method which meets the requirement of a national medicine inspection sample and is used for measuring ceftizoxime sodium high polymer is established.

Description

[0001] technical field [0002] The invention belongs to the technical field of medicine, and in particular relates to a method for preparing and detecting ceftizoxime sodium. Background technique [0003] Ceftizoxime sodium (ceftizoxime sodium) is also known as Yibao Shiling, and its main component and chemical name are {[ 6R-[ 6 ( , 7 ( ( Z ) ) ) ] -7{[ [ 2, 3-dihydro -2-imino-4-thiazolyl](methoxyimino)acetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]octane-2 -ene-2-carboxylic acid sodium salt. Its structural formula is as follows: [0004] Molecular formula: C 13 h 12 N 5 NaO 5 S 2 [0005] Molecular weight: 405.39 [0006] The third-generation cephalosporin antibiotic developed for Fujisawa Pharmaceutical Co., Ltd. (Fujisawa), Japan, has the characteristics of being stable to β-lactamase, and has a wide antibacterial spectrum, low toxicity, enzyme resistance, low toxicity and permeability It crosses the blood-brain barrier and is widely used clinically.
