Abstract

The invention relates to novel application of corilagin or a pharmaceutically acceptable corilagin salt, in particular to application of the corilagin or the pharmaceutically acceptable corilagin salt in treating or preventing diseases related to gastric acid hypersecretion such as hyperchlorhydria, peptic ulcer and chronic gastritis.

Description

technical field [0001] The present invention relates to a new application of corilagin or a pharmaceutically acceptable salt thereof, in particular to the use of corilagin or a pharmaceutically acceptable salt thereof for treating or preventing diseases related to hypersecretion of gastric acid, such as hyperacidity, peptic ulcer, Chronic gastritis and other diseases. Background technique [0002] Hyperacidity refers to excessive secretion of gastric juice (including hydrochloric acid and pepsin and other components), which makes patients feel stomach discomfort, acid reflux, and heartburn (stomach burning sensation). Mild hyperacidity is mainly characterized by repeated gastric burning and acid reflux. If the gastric mucosa is damaged by excessive gastric acid, it will also cause symptoms such as stomach pain, nausea, and vomiting. Hyperacidity may further develop into peptic ulcer , and even ulcer perforation. [0003] Drugs for the treatment of hyperacidity can be divid...
