Abstract

The invention provides a combined drug of pantoprazole and domperidone and in particular provides application of pantoprazole and domperidone to preparing combined injections for treating gastric ulcer, duodenal ulcer, gastro-esophageal reflux diseases or functional dyspepsia. The invention also provides the combined injections for treating gastric ulcer, duodenal ulcer, gastro-esophageal reflux diseases or functional dyspepsia, including different specifications of unit preparations, pantoprazole and domperidone for simultaneous, respective or successive administration and preparations prepared by pharmaceutically acceptable vectors. The weight ratio of pantoprazole and domperidone is 1:1-5:1, and the pantoprazole and domperidone contain excipients, stabilizing agents, etc. Through combined injection administration, the invention improves the bioavailability of pantoprazole and domperidone and ensures the treatment effects to be obviously better.

Description

technical field [0001] The present invention relates to the combined medicine of pantoprazole and domperidone, specifically, the application in the preparation of combined injection medicine for treating gastric ulcer, duodenal ulcer, gastroesophageal reflux disease or functional dyspepsia. Background technique [0002] Pantoprazole is a proton pump inhibitor (PPI), which is relatively stable under neutral and weakly acidic conditions, and is rapidly activated under strongly acidic conditions. has better selectivity. It can specifically inhibit the H+, K+-ATPase on the secretory microtubules formed by the apical membrane of the parietal cell and the tubular vesicle in the cytoplasm, causing irreversible inhibition of the enzyme, thereby effectively inhibiting the secretion of gastric acid. Since H+, K+-ATPase is the last process of parietal cell acid secretion, pantoprazole has a strong ability to suppress acid. It can not only non-competitively inhibit gastric acid secret...
