Abstract

The present invention relates to colon soluble hard medicine capsule disintegrated in colon and its production process. The colon soluble hard hollow capsule includes skeleton layer and coating layer. The production process includes the following steps: dipping the skeleton layer material solution with mold and stoving; coating the skeleton layer material with coating layer; stoving and curing; demolding; cutting; matching; and inspection. The colon soluble hard hollow capsule has stable quality, may be disintegrated in fixed position, and suitable for colon administration. The hollow capsule may be filled with medicine, solid, liquid and soft matter, which are released in colon.

Description

1. Technical field: [0001] The invention relates to a medicinal hard capsule which is orally disintegrated in the colon of a human body and a production process, and belongs to the innovative technology of the colon-coated enteric-coated hollow hard capsule and the production process. 2. Background technology: [0002] The disadvantages of the existing colonic-coated enteric-coated hollow hard capsules are that the quality is not stable enough, especially it is difficult to achieve localized disintegration, and it cannot meet the needs of some medicines that need to be disintegrated in the human colon. 3. Contents of the invention: [0003] The purpose of the present invention is to provide a colonic-coated enteric-coated hollow hard capsule that is stable in quality, can realize localized disintegration, and is suitable for colon-specific drug delivery in consideration of the above problems. [0004] Another object of the present invention is to provide a simple and conve...
