Problems solved by technology

[0010] In order to improve the stable performance of rabeprazole sodium, it is also convenient for storage and transportation, and it is made into the dosage form of rabeprazole sodium freeze-dried powder injection, but the injection rabeprazole sodium powder injection of the prior art is in the aqueous solution The dissolution in the solution is relatively slow, and the number of insoluble particles in the solution after dissolution is relatively large, which brings inconvenience to the injection.

Abstract

The invention provides a rabeprazole sodium composition which comprises the active ingredients of rabeprazole, mannitol and ethylene diamine tetraacetic acid, wherein the weight ratio of ethylene diamine tetraacetic acid to rabeprazole sodium is 0.05-0.5:1. The method for preparing the composition into solid powder-needle preparation comprises the following steps: dissolving the ethylene diamine tetraacetic acid solution with the prescription amount into injection water, adding and stirring the rabeprazole sodium with the prescription amount at a temperature of 25-35 DEG C for dissolving, then adding mannitol with the prescription amount, stirring the mannitol for dissolving, cooling to a room temperature, and regulating the pH value of the solution to 11.5-12.5; adding active carbon into the confected solution, stirring and filtering for decarburization, and freezing and drying the obtained filtrate to obtain the rabeprazole frozen powder needle. The rabeprazole frozen powder needle has full appearance, favorable stability and solubility and little insoluble grains in the injection.

Description

technical field [0001] The present invention relates to a rabeprazole sodium composition, in particular to a rabeprazole sodium composition and a preparation method thereof. Background technique [0002] Ulcer disease is a common type of disease, and it is prone to recurrent clinically, often accompanied by serious complications, such as gastric and duodenal ulcers, which can be complicated by upper gastrointestinal bleeding and perforation, which seriously threaten people's health. Proton pump inhibitors are powerful weapons in the fight against ulcer disease. Japan's Eisai Company's proton pump inhibitor (Proton Pump Inhibitors, PPI) anti-ulcer drug rabeprazole is following Astra's omeprazole, Takeda's lansorazole (lansorazole) and Byk Gulden's panax The fourth PPI developed after pantoprazole. [0003] The chemical name of Rabeprazole Sodum is: 2-[[[4-(3-methoxypropoxy)-3-methyl-2-pyridyl]methyl]sulfinyl]- 1H-Benzimidazole Sodium. [0004] Chemical Structure: [0005...
