Problems solved by technology

[0005] In order to solve the problem that the above-mentioned gelatin hollow capsules are prone to cross-linking reactions, the invention provides a gelatin hollow capsule with anti-crosslinking effect and a preparation method thereof. The gelatin hollow capsules prepared by the present invention have obvious cross-linking resistance, By adjusting the raw material index and excipient composition of gelatin hollow capsules, the capsules that are prone to cross-linking reactions can avoid cross-linking reactions and affect the dissolution rate of the preparation during the accelerated stability test, and at the same time reduce the biological risk of cross-linking capsules. The risk of non-equivalence of efficacy experiments

Abstract

The invention provides a gelatin hollow capsule with anti-crosslinking effect and a preparation method thereof. The composition ratio of the gelatin hollow capsule is as follows: 1000 parts of gelatin, 2-10 parts of plasticizer, 2-15 parts of antioxidant, 2-15 parts of 10 parts of pH regulator, 0-30 parts of colorant, 2800-4000 parts of purified water, the concentration of the gelatin glue is 25%-35%. The preparation method of the above-mentioned gelatin hollow capsule with anti-crosslinking effect is also provided. The gelatin hollow capsule prepared by the present invention has obvious anti-crosslinking effect, by adjusting the raw material index and auxiliary material composition of the gelatin hollow capsule, the capsule that is prone to crosslinking reaction can avoid crosslinking reaction in the accelerated stability test process. Affect the dissolution rate of the preparation, and at the same time reduce the risk of non-equivalence in the bioequivalence experiment of the easily cross-linked capsules.

Description

Technical field [0001] The present invention belongs to the field of pharmaceutical excipient technology, in particular to a gelatin hollow capsule having an anti-crosslinking effect and a method of preparation thereof. Background [0002] As the most popular dosage form for consumers, capsules have been widely used in the development of pharmaceutical preparations, with gelatin hollow capsules accounting for the highest proportion. The capsule effectively masks the taste and odor of the contents and is easy to swallow, but the crosslinking reaction of gelatin hollow capsules is one of the important factors affecting the detection of in vitro dissolution of capsules, and the dissolution degree is an important indicator of the quality control of solid oral preparations. [0003] Gelatin capsule raw materials, fillers and storage conditions are the main factors causing crosslinking reaction, gelatin capsule crosslinking phenomenon refers to the preparation in the unenzing dissoluti...
