Large intestinal dissociative hard capsules

A large intestinal dissociative hard capsule comprises a capsule mainly composed of chitosan having a coating layer of a polymer soluble in a liquid having pH of at least 5 on the surface of the capsule. The chitosan capsule is prepared from a solution obtained by dissolving the chitosan in an aqueo...

description A large intestinal dissociative hard capsule comprises a capsule mainly composed of chitosan having a coating layer of a polymer soluble in a liquid having pH of at least 5 on the surface of the capsule. The chitosan capsule is prepared from a solution obtained by dissolving the chitosan in an aqueous 1% by weight acetic acid solution to yield a chitosan solution having a viscosity at 20 DEG C not higher than 100 cps; the degree of deacetilation of the chitosan is from 60 mol% to 98 mol%.
