Abstract:
The present invention is directed to film coating systems for use on oral dosage forms such as compressed tablets and orally-ingestible substrates which have improved pearlescent qualities. The film coating systems can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the pearlescent film coating is prepared as a dry powder mixture containing a cellulosic polymer, a detackifier, a gloss enhancer, and a pearlescent pigment. Film coating compositions containing an aqueous suspension of the powder mixtures, methods of applying the coatings to substrates and the coated substrates are also disclosed.
