FILM COATINGS OF IMMEDIATE RELEASE, CONTAINING MEDIUM-CHAIN GLYCERIDES, AND SUBSTRATES COATED THEREWITH

摘要

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.
