Abstract

The invention relates to a cefoxitin sodium medicinal composition, powder injection and a preparation method thereof. The medicinal composition consists of cefoxitin sodium, histidine and hydroxypropyl-beta-cyclodextrin, wherein the weight of the histidine is 3 to 8 percent of that of the cefoxitin sodium, and the weight of the hydroxypropyl-beta-cyclodextrin is 5 to 10 percent of that of the cefoxitin sodium. The medicinal composition is high in stability, related medicament content of the medicinal composition is further lower than that of a commercial cefoxitin sodium product, gastrointestinal side effect is low, the quality of the medicaments is greatly promoted, and the safety of the medicaments is improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical inventions, and in particular relates to a cefoxitin sodium pharmaceutical composition, its powder injection and a preparation method thereof. Background technique [0002] Cefoxitin belongs to the cephalosporin antibiotics and is a semi-synthetic cephalosporin antibiotic developed by Merck Company of the United States. Cefoxitin Sodium (Cefoxitin Sodium) was first approved for marketing by Japan's Daiichi Pharmaceutical Development Company in August 1979 under the trade name "Cenomycin". Its chemical name: (6R,7S)-3-[(1-carbamoyloxy)methyl]-7-methoxy-8-oxo-7-[2-(2-thienyl)acetamido] - 5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid sodium salt. Its structural formula is as follows: [0003] [0004] The antibacterial effect of cefoxitin sodium is similar to other second-generation cephalosporin antibiotics, but because its structure contains a 7α-methoxy group, it greatly reduces the hyd...
