Description
Technical field
The invention belongs to biomedicine field, particularly relate to a kind of starch capsule and preparation method thereof.
Background technology
There is a lot of shortcoming in gelatine capsule itself, such as: is prone to cooperating microorganisms, the easy moisture absorption, the low then pliability of ambient humidity
Poor, frangible, ambient humidity is the most then prone to stick together, thus can not load easy moisture absorption or the medicine to water sensitive；Gelatin divides
Subchain contains a large amount of reactive groups, it is easy to fill drug reaction；Additionally, due to religious reasons, gelatine capsule by Moslem and
Jewry and the conflict of vegetarian.
Being improved in industry, such as Chinese patent discloses a kind of starch capsule and preparation method thereof, application number
201510405995.4, a kind of starch capsule and preparation method thereof, this premixing auxiliary material consists of the following composition: hydroxypropyl starch
30-40 part, starch 20-30 part, mannitol 1-5 part, hypromellose 0.5-2 part, sorbitol 0.5-5 part, polyvidone 1-4
Part.
The deficiency that technique scheme exists is: directly use starch to have clear as major ingredient, the capsule made
Lightness relatively low (capsule is the brightest), the shortcomings such as stability is the highest.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of starch capsule, and this starch capsule has clarity height and storage
Stability advantages of higher.Additionally, the present invention also provides for the preparation method of a kind of starch capsule.
