Abstract
The present invention is directed to immediate release film coating compositions for use on oral dosage forms such as compressed tablets and other orally-ingestible substrates which contain medium chain glycerides as detackifiers. 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 polyvinyl alcohol and the medium chain glycerides are mixtures of caprylic (8 carbon chain) and capric (10 carbon chain) mono- and diesters of glycerin. Aqueous suspensions comprising the inventive film coating compositions, methods of applying the coatings to substrates and the coated substrates themselves are also disclosed.
