Abstract

The present invention relates to a medicine composition with domperidone maleate. It is characterized by that said medicine composition is micropowdered, and can be used for invigorating function of gastrointestinal tract and curing the diseases of dyspepsia and nausea-vomiting, etc. Said micropowdered domperidone maleate preparation can raise its bioavailability. Besides, said invention also provides its preparation method.

Description

technical field [0001] The present invention relates to a pharmaceutical composition containing micronized domperidone maleate (Domperidone Maleate). Background technique [0002] Domperidone is a peripheral dopamine receptor blocker, acting directly on the gastrointestinal wall, increasing the tension of the lower esophageal sphincter, preventing gastroesophageal reflux, enhancing gastric motility, promoting gastric emptying, coordinating gastric and duodenal motility, inhibiting Nausea, vomiting, and can effectively prevent bile reflux without affecting gastric secretion. It is clinically used to relieve dyspepsia symptoms caused by delayed gastric emptying, gastrointestinal reflux, and esophagitis, such as: upper abdominal distension, abdominal distension, upper abdominal pain, belching, flatulence, with or without Heartburn with regurgitation of stomach contents. Nausea and vomiting caused by functional, organic, infectious, diet, radiation therapy or chemotherapy. ...
