Abstract
The present invention is directed to film coating compositions for use on oral dosage forms such as compressed tablets and other orally-ingestible substrates which contain a fine particle size detackifier. The film coating compositions can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the polymer is either polyvinyl alcohol or a copolymer of polyvinyl alcohol. Aqueous suspensions comprising the inventive film coating compositions, methods of applying the coatings to substrates and the coated substrates themselves are also disclosed.
