Abstract

The invention provides an S-pantoprazole sodium composite for injection, which is prepared through a method comprising the following steps of: (1) preparing liquid medicine: selecting S-pantoprazole sodium and edetic acid or edetate as raw materials, wherein the weight ratio of the S-pantoprazole sodium and the edetic acid or the edetate is 1:0.01-0.1; weighing a right amount of the raw materials, placing into a preparation tank, adding water for the injection till the weight of a solution is 11.82-118.2 times more than that of the S-pantoprazole sodium, stirring for dissolution, uniformly mixing, and regulating the pH value of the solution at 10.0-12.5; (2) finishing active carbon; (3) absorbing; (4) carrying out aseptic filtration and split charging; and (5) carrying out vacuum freeze drying so as to obtain the S-pantoprazole sodium composite for the injection. The S-pantoprazole sodium composite for the injection and the preparation method thereof can both ensure that product heat sources, visible foreign matters and insoluble particles meet the requirements of injections for the injections, i.e. S-pantoprazole sodium preparing liquid medicine which has higher pH.

Description

technical field [0001] The invention relates to an S-pantoprazole sodium composition for injection and a preparation method thereof, belonging to the technical field of medicine preparation. Background technique [0002] The chemical name of pantoprazole sodium is 5-difluoromethoxy-2-[(3,4-dimethoxy-2-pyridyl)methyl]sulfinyl-1H-benzoimidazole Sodium, the structural formula is [0003] [0004] Pantoprazole is a sulfoxide and a chiral compound in which the sulfur atom is the stereogenic center. Thus, pantoprazole is a racemic mixture of two single enantiomers, R and S, and its salts also have corresponding configurations. Described in U.S. Patent No. 5,888,535, S-pantoprazole sodium has a stronger effect of inhibiting gastric acid secretion than racemic pantoprazole sodium and the R-type isomer. S-pantoprazole sodium can be studied as a proton pump inhibitor like esomeprazole (esomeprazole) for the treatment of diseases related to gastric acid secretion disorders, such ...
