Abstract

The invention relates to the technical field of medicine, in particular to an injection powder and injection preparation of a cefoperazone sodium-tazobactam combination. The injection powder and injection preparation comprises cefoperazone sodium, tazobactam combination and lignocaine hydrochloride, wherein the mass ratio of the cefoperazone sodium to the tazobactam combination to the lignocaine hydrochloride is 4:1:(0.01-0.05). Compared with a positive medicament control group, the injection powder and injection preparation of the cefoperazone sodium-tazobactam combination provided by the invention has the advantages of capability of relieving injection pain and remarkable improvement on the curative effect.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a cefoperazone sodium and tazobactam sodium composition powder for injection. Background technique [0002] Cefoperazone, chemical name: (6R,7R)-3-[[(1-methyl-1H-tetrazol-5-yl)sulfur]methyl]-7-[(R)-2-(4 -Ethyl-2,3-dioxo-1-piperazinecarbonylamino)-2-p-hydroxyphenyl-acetylamino]-8-oxo-5-thia-1-azabicyclo[4,2 , 0] Oct-2-ene-2-formic acid sodium salt, the molecular formula is: C 25 h 26 N 9 NaO 8 S 2 , the molecular weight is: 667.66, and the structural formula is: [0003] [0004] Cefoperazone is a third-generation cephalosporin antibiotic with a broad antibacterial spectrum and strong effect. It has a strong antibacterial effect on Pseudomonas aeruginosa. It achieves bactericidal effect by inhibiting the biosynthesis of sensitive bacterial cell walls. The characteristics of its action are: strong against anaerobic bacteria and Gram-negative bacteria, (including Pseudomo...
