Abstract

The invention relates to an aseptic powder injection of cefamandole nafate and a preparation method thereof; the aseptic powder injection of cefamandole nafate comprises cefamandole nafate and anhydrous sodium carbonate; after the improvement of the preparation technology, the dosages of auxiliary material are small, and therefore the aseptic powder injection of cefamandole nafate obtained is good in stability and low in cost. The synthetic process of the drug material of cefamandole nafate adopted by the invention has simple operation process, low material cost and moderate reaction conditions; the cefamandole nafate produced has high purity and high productive rate.

Description

technical field [0001] The invention relates to a cefamandole sodium powder injection and a preparation method thereof, and also relates to a preparation method of a crude drug. Background technique [0002] Cefamandole sodium (Cefamandole Nafate) is a second-generation cephalosporin created by E. Lilly Company of the United States in 1972. It was used clinically abroad in 1978 and was successfully developed in China in 1979. Cefamandole sodium is a cephalosporin with strong bactericidal effect, which has some advantages of the first-generation and third-generation cephalosporins. It has strong antibacterial activity against most Gram-positive bacteria, some negative bacteria and Clostridium dentifrice, relatively stable to β-lactamases, low toxicity, high blood concentration, wide tissue distribution, in the kidney parenchyma and bile concentration is particularly high. [0003] The chemical name of cefamandole sodium is: 7-D-(2-formyloxyphenylacetamide)-3-[(1-methyl-1H-t...
