摘要:
The present invention includes pH dependent, dry film coating compositions containing calcium silicate for use on orally-ingestible substrates such as tablets and the like. The film coating compositions can be applied as an aqueous suspension either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the polymer is either an enteric or reverse-enteric polymer. Methods of preparing the dry film coatings, methods of preparing corresponding aqueous suspensions, methods of applying the coatings to substrates and the coated substrates themselves are also disclosed.
