Abstract

The invention relates to a coating material, and particularly relates to a water resistance type film coating composition and an application thereof. The water resistance type film coating composition comprises the following components by weight parts: 3-15 parts of polyacrylic resin IV and 1-5 parts of plasticizer which is stearic acid. Before use, the composition is dissolved in an absolute ethyl alcohol, or is mixed together with the absolute ethyl alcohol to be stored or used. The water resistance type film coating composition provided by the invention has an excellent water resistance type performance and good sensitiveness to pH change; and after the medicine is coated according to a conventional film coating technology, the release behavior of the medicine can be obviously improved, the stability of dosage form effervescent tablets sensitive to water and products sensitive to water in the production and storage period is facilitated.

Description

technical field

[0001] The invention relates to a coating material, in particular to a water-resistant film coating composition and its application. Background technique

[0002] Film coating refers to the coating of one or more layers of relatively stable films mainly composed of polymer film-forming materials on the surface of tablet cores, granules or pellets by some technical means.

[0003] Film coating originated in the UK. The original purpose was to color the product with pigments to improve the visual effect of the product and to distinguish different specifications of the same product. Nowadays, with the increase in the types of film coating materials and additives, the coating equipment Gradually refined and intelligent, the film coating process has been widely used in oral solid preparations such as tablets, granules, and pellets. In foreign countries, film coating has replaced sugar-coating. In China, film-coated tablets have also replaced sugar-coated tablets. ...
