(57) [Summary]nThe present invention relates to a device for releasing a drug having anti-lutein hormone characteristics in a controlled state over a long period of time, wherein the device contains a core containing the drug and, optionally, a membrane containing the core Wherein the core and / or membrane is formed from a siloxane-based elastomeric composition, the composition comprising at least one elastomer and optionally a non-crosslinked polymer About. In this device, the elastomeric composition contains poly (alkylene oxide) groups, and the poly (alkylene oxide) groups are present in the elastomer or polymer as an alkoxy-terminated graft or block of polysiloxane units. The graft or block is bonded to the polysiloxane unit by a silicon-carbon bond, or exists as a mixture of the above forms. |
