Abstract

The invention belongs to the field of medicine preparation, and relates to a hollow starch capsule and a preparation process thereof. Each weight component of the starch hollow capsule: 40-70 parts of high amylose starch, 20-60 parts of high amylopectin, 5-15 parts of pregelatinized starch, 5-20 parts of konjac gum, 60-90 parts of deionized water. This kind of starch hollow capsule has the characteristics of low cost, good quality, strong water retention, and meets the standards of "Chinese Pharmacopoeia", and has good properties such as short disintegration time and low friability, and has achieved good results in practical applications. effect and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of medicine and health products, in particular to a hollow starch capsule and a preparation process thereof. Background technique [0002] At present, empty capsules in my country are mainly prepared from gelatin as the main raw material. Gelatin is the hydrolyzate of connective tissues such as animal skin and bone. Gelatin capsules have good properties such as low friability and short disintegration time limit, but moisture has a great influence on gelatin. Since gelatin capsules themselves contain hydrophilic amino groups and carboxyl groups, they will not The water content is 13%-16%, which makes the hydrophilic substances in the content migrate to the gelatin capsule shell, and the drug with strong hygroscopicity interacts with the capsule under high humidity conditions, causing more drug powder to stick to the inner wall of the capsule , resulting in underutilization of drugs. It will lose water and h...
