Abstract

The present invention provides a kind of colon target orientation preparation for curing colitis and its preparation method. Said preparation is formed from 250-500g of montmorillonite, 3-15g of binding agent and 0.20-3.0g of lubricating agent. Said colon target orientation preparation can be made into oral enteric soluble tablet or oral enteric soluble capsule. Besides, said invention also provides the concrete steps of its preparation method.

Description

(1) Technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a colon-targeted and localized preparation for treating colitis and a preparation method thereof. (2) Technical background [0002] Montmorillonite medicine has a network structure and non-uniform charge distribution. It has a fixed inhibitory effect on digestive tract viruses, bacteria and the toxins they produce, and has a fixed covering ability on the digestive tract mucous membrane. At present, it is widely used clinically, and it can selectively bind to mucosal fluid proteins and cover the mucosal surface. Prevent viruses, germs, and toxins from eroding. It also locally stops bleeding in the digestive tract by activating coagulation factors VI, VII, and XII. By strengthening the barrier function of the digestive tract mucosa, it helps the regeneration and repair of the epithelial tissue of the digestive tract as well as fixes and absorbs it, so that the inflammation of ...
