Problems solved by technology

[0006] After a long period of serious research, the inventors found that the three materials, dioleoylphosphatidylcholine, cholesterol and sodium glycocholate, were combined according to a specific ratio, and prepared into a liposome with rabeprazole sodium according to a certain ratio. Plastids, and then prepare the liposomes with alkaline substances and other solid common excipients into solid preparations, which can solve the technical problems of rabeprazole sodium stability and poor encapsulation efficiency, and obtain unexpected preparation effects. thus providing formulations of good quality

Abstract

The invention discloses rabeprazole sodium liposome enteric-coated tablets and a preparation method and application thereof to treating gastroesophageal reflux disease (GERD). The rabeprazole sodium liposome enteric-coated tablets comprise rabeprazole sodium liposome solid, alkaline substances and other common auxiliary materials for a solid preparation, wherein the rabeprazole sodium liposome solid comprises the following components in part by weight: 10 to 20 parts of rabeprazole sodium, 40 to 90 parts of dioleoyl phosphatidylcholine, 15 to 50 parts of cholesterol and 8 to 30 parts of sodium glycocholate. The rabeprazole sodium liposome enteric-coated tablets have the advantages of improving stability, increasing dissolution, solving the problem of color change when being heated, and the like, and when the rabeprazole sodium liposome enteric-coated tablets are used for treating the GERD, the curative ratio is higher, the total effective rate is higher, and the clinical superiority is more obvious.

Description

technical field [0001] The invention relates to a rabeprazole sodium liposome enteric-coated tablet and a preparation method thereof, as well as its application in the treatment of gastroesophageal reflux disease, belonging to the technical field of medicine. Background technique [0002] With the change of people's eating habits, the incidence of gastroesophageal reflux disease (GERD) patients is increasing year by year. Gastroesophageal reflux disease (GERD) refers to the inflammation, erosion, ulcer and fibrosis of the esophageal mucosa caused by the reflux of gastric and duodenal contents into the esophagus. The clinical manifestations are burning sensation in the stomach, chest pain, dysphagia and other symptoms, and some GERD patients have no endoscopic manifestations of esophagitis. Gastroesophageal reflux disease (GERD) is a common digestive system disease in my country. Epidemiological survey results show that the incidence rate of GERD is 5.77%. The main diagnosis...
