Abstract

A diarrhea-relieving with astringents colon-positioning enteric-coated pharmaceutical preparation and the preparation method thereof belong to a colon-positioning enteric-coated pharmaceutical preparation technical field. Active ingredients of the preparation are montmorillonite and Rhizome Rhodesia; adopting coating treatment with colon coating materials, the medicine does not disintegrate and release on an upper digestive tract; the preparation arrives at a colon part and disintegrates rapidly and releases the medicine in order that the medicine can be contacted with an intestinal focus part directly to improve curative effect.

Description

technical field [0001] The invention relates to a colon-targeted enteric-coated medicinal preparation, in particular to a colon-targeted enteric-coated medicinal preparation for astringent intestines for antidiarrheal and a preparation method thereof. Background technique [0002] Montmorillonite drug has a lamellar structure and non-uniform charge distribution. It has a fixed inhibitory effect on digestive tract viruses, bacteria and their toxins, and has a strong covering ability on the digestive tract mucosa. Proteins combine with each other to repair both qualitatively and quantitatively, and improve the defense function of the mucosal barrier against attacking factors. The montmorillonite does not enter the blood circulation system, and is excreted together with the fixed attack factor through the peristalsis of the digestive tract itself. The montmorillonite does not affect the X-ray examination, does not change the color of the stool, and does not change the normal in...
