Abstract

PURPOSE: To form an elastic coating film easily soluble in intestinal juice, by applying a coating agent such as an acid succinyl ester of cellulose ether to a solid medicine.
CONSTITUTION: Solid medicine such as tablet, granule, capsule, etc., is coated with a coating solution obtained by dissolving an acid succinyl ester of alkyl-and/or hydroxyalkyl-substituted cellulose or an aliphatic monoacyl mixed ester in a solvent such as acetone, methylene chloride, ethyl acetate, etc., by a coating means such as pan-coater, drum-type coater, etc. The acid succinyl ester of cellulose ether is prepared by the esterification reaction of a cellulose ester with succinic anhydride and an aliphatic monocaroboxylic acid anhydride
