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 water-soluble polymer and guar gum. 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 water-soluble polymer is a cellulosic or vinyl polymer. Aqueous suspensions containing the inventive film coating compositions and the coated substrates themselves are also disclosed. The resulting coated substrates have relatively low coefficients of static and dynamic friction on wet surfaces rendering them easier to swallow than prior art compositions.
