Abstract

A coating auxiliary material for extract preparations of traditional Chinese medicines, the main components of which include by weight: 15-20% of film-forming agent, 20-25% of plasticizer, 20-30% of colorant and 30-35% of auxiliary additives . The invention also discloses a preparation method of a coating auxiliary material used for extract preparations of traditional Chinese medicines and a coating method. The coating powder of the invention has good coating power, can cover the defects of the tablet core, and improve the appearance of the coating; The coating film has excellent barrier properties, and its moisture-proof and taste-masking effects on pharmaceutical preparations are better than ordinary coating materials; the coating preparation disintegrates quickly and has no effect on the release of pharmaceutical ingredients.

Description

technical field [0001] The invention relates to the field of coating auxiliary materials, in particular to a coating auxiliary material for Chinese medicine extract preparations, a preparation method and a coating method. Background technique [0002] Most of the solid preparations of traditional Chinese medicine are extracted by water or ethanol in the preparation process. However, due to the complex composition of the medicinal materials, the extracts produced by this method are often rich in substances that are highly hygroscopic such as sugars, resins, and tannins. Softening, darker appearance, agglomeration, reduced fluidity and even mildew appear, which seriously affects the quality and curative effect of medicines, and brings great difficulties to the production and storage of medicines. For a long time, in the process of pharmaceutical preparations, solid granules or tablet cores are often coated, and film coating is used as a barrier to help isolate the dosage form ...
