Abstract

The invention relates to a composition of cefazolin sodium pentahydrate and sulbactam sodium. Compared with the antibacterial effect of cefazolin sodium pentahydrate cefazolin sodium, the composition has excellent antibiotic activity and low resistant rates.

Description

technical field [0001] The invention relates to a composition of cefazolin sodium pentahydrate and sulbactam sodium. Background technique [0002] Cefazolin sodium pentahydrate is based on α-type cefazolin sodium, and its finer structure has been discovered. In the microstructure, a single crystal formed by two molecules of cefazolin, ten sub-water and one sodium ion Chelating structure. Cefazolin and sodium ions are combined by coordination bonds and covalent bonds. In the crystalline state, two Cefazolin molecules are arranged to form a tunnel-like cavity, and water molecules and sodium ions exist in the cavity. Azoline together forms a chelated macromolecular structure and is a stable chelated crystal. [0003] The chemical name of cefazolin sodium pentahydrate is: (6R, 7R)-3-[[(5-methyl-1,3,4-thiadiazol-2-yl)sulfur]methyl]-7-[ (1H-tetrazol-1-yl)acetamido]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid sodium salt pentahydrate. Its structural formula is a...
