Abstract: The present invention is directed film coating compositions for use on oral dosage forms such as compressed tablets and other orally-ingestible substrates which contain a water-soluble polymer, an opacifying agent such as, calcium carbonate or starch, and isomalt. The film coating compositions can be in the form of a fully formulated dry blend or as an aqueous suspension which can be applied either directly to a substrate or after the substrate has been coated with a subcoat. Oral substrates such as tablets coated with the film coating compositions are also disclosed and have high opacity and overall excellent appearance.
