Abstract

The invention discloses a pharmaceutical adjuvant film coating material and a preparation method thereof. The film coating material is prepared from formula components in parts by mass as follows: 5-7 parts of hydroxypropyl methylcellulose, 1-3 parts of filler, 3-5 parts of polypropylene, 2-4 parts of polyethylene glycol, 1-3 parts of cellulose ether, 2-4 parts of white cement, 3-5 parts of polyethylene glycol, 11-13 parts of talc powder, 8-12 parts of ferric oxide, 16-18 parts of pectin, 6-10 parts of Tween, 4-6 parts of argil and 10-20 parts of tap water. With the adoption of the film coating material, the spraying speed can be increased, the temperature of a substrate bed is reduced, the internal stress of the films is reduced, the occurrence rate of coating films is reduced, and the substrate adhesion phenomenon easily caused by use of water as a carrier can be avoided.

Description

technical field [0001] The invention relates to the field of film materials, in particular to a pharmaceutical auxiliary material film coating material and a preparation method thereof. Background technique [0002] Film coating is one of the major achievements in the development of advanced preparation technology in recent years. It is considered to be a technology with strong technology, great difficulty and great impact on product quality. This technology must be based on reliable detection methods and can withstand Practice and the test of time, film coating is a film that wraps polymers outside the solid dosage form, and the film thickness is usually 20-100 microns. Coating materials are divided into gastric-soluble type, enteric-coated type, and sustained-release type according to type. The prescription usually consists of the following components: ①film-forming agent ②plasticizer ③colorant / opacifier ④solvent, the pharmaceutical excipient film coating material made of ...
