Abstract

The invention relates to a pharmaceutical composition with a cefminox sodium sterile mixed powder form, and the pharmaceutical composition comprises cefminox sodium, anhydrous sodium carbonate and sodium benzoate, wherein the mass ratio of the cefminox sodium, the anhydrous sodium carbonate and the sodium benzoate is 100g:(0.1-0.5)g:(0.1-1.0)g. Due to the combined application of the cefminox sodium, the anhydrous sodium carbonate and the sodium benzoate, the heat stability of the cefminox sodium can be greatly improved, and the stability of the cefminox sodium in a solution state can be improved, so that the clinical use safety is improved. Furthermore, the invention also relates to a preparation method of the pharmaceutical composition, and the preparation method is simple and practicable in technology, thus being suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a pharmaceutical composition in the form of cefminox sodium aseptic mixed powder, which contains anhydrous sodium carbonate and sodium benzoate. Background technique [0002] Cefminox sodium, the English name is Cefminox Sodium, the chemical name is (6R,7S)-7β-[(S)-2-[(2-amino-2-carboxyethyl)sulfur]acetamido]-7α-methanol Oxy-3-[[(1-methyl-1H-tetrazol-5-yl)thio]methyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]octyl- 2-ene-2-carboxylic acid sodium salt heptahydrate is a cephalosporin widely used clinically, and its structural formula is: [0003] [0004] Molecular formula: C 16 h 20 N 7 NaO 7 S 3 .7H 2 O, molecular weight: 667.66. [0005] Cefminox sodium is a third-generation cephalosporin antibiotic developed by Japan's Meiji Company. It has broad-spectrum antibacterial activity against Gram-positive and Gram-negative bacteria, especially Escherichia coli, Klebsiella, and influenza. H...
