Problems solved by technology

This patent is relatively simple, and the raw and auxiliary materials are directly mixed, sieved, and packaged, but the stability is poor, and when it is decomposed by light and heat, the aqueous solution is quickly hydrolyzed and oxidized, and it is easy to deteriorate, which affects the efficacy and quality of the medicine.
[0006] CN101537009A discloses an easy-to-mix ceftriaxone sodium / tazobactam sodium pharmaceutical composition, but it also has poor stability and is easily deteriorated and decomposed when exposed to light and heat, resulting in a decline in quality and affecting the curative effect
The microspheres of the ceftriaxone sodium / tazobactam sodium pharmaceutical composition have not been reported so far

Abstract

The invention discloses microsphere injection of a ceftriaxone sodium / tazobactam sodium drug composition, which comprises ceftriaxone sodium, tazobactam sodium, PLA, sodium glycocholate, PEG600 and trehalose. In the preferential technical scheme, the microsphere injection comprises 3 parts of ceftriaxone sodium, 1 part of tazobactam sodium, 2.5-7 parts of PLA, 3-6 parts of sodium glycocholate, 2-5 parts of PEG600 and 8-15 parts of trehalose. Compared with the prior art, the invention has the advantages of good stability, high encapsulation efficiency, preparation process suitable for industrial production and proper slow-release effect.

Description

technical field [0001] The invention relates to a ceftriaxone sodium / tazobactam sodium pharmaceutical composition microsphere injection, which belongs to the technical field of medicine. Background technique [0002] The main antibacterial ingredient of this product is ceftriaxone sodium. Ceftriaxone sodium is a third-generation cephalosporin antibiotic, which plays a bactericidal effect by inhibiting the synthesis of bacterial cell walls. , Klebsiella pneumoniae, Bacillus influenzae and indole-positive Proteus have strong effects, especially the most effective against Haemophilus. Clinically, it is mainly used for various infections caused by sensitive bacteria, such as respiratory tract infection, biliary tract infection, pyelonephritis, urinary tract infection, peritonitis, sepsis and skin soft tissue, bone, joint and other infections. Another component of this product is the β-lactamase inhibitor tazobactam sodium, which inhibits the β-lactamase produced by a variety o...
