Abstract (en)
[origin: WO9605812A1] A capsule body (6) for a controlled release device has a coating of a hydrophilic material at least inside the neck region (4) adjacent the opening (15). The hydrophilic material may be a film forming material and/or a surfactant. Its purpose is to facilitate ingress of water into the capsule body in order to release a pharmaceutical material contained therein, once the hydrogel plug (2) has swollen and become disengaged from the body after a predetermined time interval. A preferred hydrophilic coating is formed of a mixture of ethyl cellulose and sodium docusate.
