Cellulose acetate phthalate (CAP 2 ; Eastman Chemical Co., Kingsport, TN) is a cellulose derivative in which approximately one-half of the hydroxyl groups are acetylated and approximately one-fourth are esterified with one of the two acid groups of phthalic acid;
The ultimate objective of this work is to develop a device that can be triggered by morphine to release naltrexone. In this device, naltrexone is dispersed in cellulose acetate phthalate microspheres which are then spray-coated with a trilaurin protective coating. The microspheres are contained with
