Abstract

The invention provides a capsule for treating gastric diseases such as gastritis and peptic ulcer, as well as the preparing process, wherein the capsule is prepared from Zuojin extract and stomach floating auxiliary material by a weight ratio of 1:0.5-5, Zuojin extract is prepared from coptis root and evodia rutaecarpa by a weight ratio of 6:1 through extracting, the stomach floating auxiliary material comprises hydrophilic gel material, foaming agent and release modifier. The preparing process comprises the steps of coating evodia rutaecarpa extract volatile oil with beta-cyclodextrin, merging evodia rutaecarpa dross and coptis root, extracting with ethanol, mixing the extract with auxiliary materials homogeneously, packing into capsules, and heating for hot-setting.

Description

1. Technical field [0001] The invention relates to the field of traditional Chinese medicine preparations, in particular to a Zuojinwei floating capsule and a preparation method thereof. 2. Background technology [0002] Zuojin Wei Floating Capsule is an improvement of the dosage form of Zuojin Pill or Zuojin Capsule, which are already on the market. Zuojin Wan comes from "Danxi Xinfa". It is composed of the monarch drug Coptis chinensis and the adjuvant drug Evodia rutaecarpa in a ratio of 6:1. It is recorded in various editions of the Chinese Pharmacopoeia. Pain in the stomach and hypochondriac, bitter and noisy mouth, vomiting of sour water, dislike of hot drinks. At present, it is commonly used clinically for acute and chronic gastritis and peptic ulcer, and the curative effect is remarkable. Modern pharmacological studies have shown that Zuojin Wan has the functions of anti-ulcer, protecting gastric mucosa, inhibiting gastric acid secretion, and affecting gastrointest...
