Problems solved by technology

[0003] At present, cefotiam is mainly in the form of powder injection, but due to the influence of various factors, the dissolution rate of existing products is not satisfactory. Since it does not contain preservatives, it must be used immediately after dissolution
For this reason, it is beneficial for patients to develop a convenient cefotiam freeze-dried injection preparation to increase the dissolution rate and avoid stability problems caused by long-term storage.

The composition comprises cefotiam hydrochloride, anhydrous sodium carbonate, mannitol, vitamin C, and a sodium hydrogen citrate and trisodium citrate buffering solution.

Description

Technical field: [0001] The invention relates to a new pharmaceutical preparation composition, in particular to an injection preparation of cefotiam, its prescription, application and preparation method. Background technique: [0002] Cefotiam, English name: Cefotiam Hydrochloride. Its chemical name is (6R-trans)-7-[[(2-amino-4-thiazolyl)acetyl]amino]-3-[[[1-[( 2-(Dimethylamino)ethyl]-1H-tetrazol-5-yl]thiomethyl]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2- En-2-carboxylic acid dihydrochloride. Molecular formula: C18H23N9O4S3 2HCl, molecular weight: 598.6. This product is white to light yellow crystalline powder, odorless. It has a wide range of antibacterial effects on Gram-negative bacteria and positive bacteria. Especially for Escherichia coli, Klebsiella, Proteus mirabilis, influenza bacillus, etc., it shows stronger antibacterial activity. For enterobacteria, Citrobacter, indole-positive common Proteus, Rettger Proteus morganii and Proteus morganii also showed good antibact...
