Abstract

The invention provides a sodium rabeprazole composition used for injection, which comprises sodium rabeprazole and disodium ethylene diamine tetraacetate, wherein, the weight ratio of sodium rabeprazole and disodium ethylene diamine tetraacetate is 1:0.02-0.1, the composition is prepared by the following steps: 1) liquid preparing: weighting sodium rabeprazole and disodium ethylene diamine tetraacetate to place into a preparation vessel, adding water for injection, stirring for dissolving and then well mixing and regulating the pH value to 10.5-11.5; 2) robber plug treating; 3) aseptic filtering and packaging; 4) vacuum freeze-drying. According to the invention, medicines such as sodium rabeprazole are easy to react with an exudate in a robber plug, so that the sodium rabeprazole composition used for injection is capable of ensuring the product visible foreign matter and insolubility particle accord with the injection requirement. The present invention can obviously improve the quality of the product, and avoids the hidden troubles brought by defective visible foreign matter and insolubility particle to clinic safe medication of patients, the composition provided in the invention has better curative effect and lower clinic side effect.

Description

technical field [0001] The invention relates to a rabeprazole sodium composition for injection, which belongs to the technical field of medicine preparation. Background technique [0002] The chemical name of Rabeprazole sodium is 2-[[[4-(3-methoxypropoxy)-3-methyl-2-pyridyl]methyl]sulfinyl]-1H- Benzimidazole sodium salt, the structural formula is [0003] [0004] Rabeprazole sodium is a new product developed by Japan's Eisai Company, code-named E-3810. It was first launched in Japan in 1997. In 1999, this product was launched in the United States and Sweden. The dosage form is enteric-coated tablets. For the treatment of gastric ulcer, duodenal ulcer, anastomotic ulcer, reflux, esophagitis, Zoller-Ellison syndrome and other indications. As a new generation of proton pump inhibitors, rabeprazole sodium has a high pKa value, is rapidly activated in the body, and combines with proton pumps to exert an acid-suppressing effect. Compared with the first-generation proton pu...
