摘要:
An osmotic system is disclosed comprising a wall comprising in at least a part of a semipermeable material that surrounds a compartment. The compartment contains an osmotic composition comprising a beneficial drug selected from the group consisting of nifedipine, prazosin and doxazosin, and a second and different osmotic composition. A passageway in the wall connects the first composition with the exterior of the system.

摘要:
An osmotic capsule is disclosed for delivering a beneficial agent formulation to an environment of use. The osmotic capsule comprises an outer semipermeable wall surrounding and laminating an inner capsule wall formed of a different polymeric composition than the outer wall. The walls define an interior space containing the beneficial agent formulation. A passageway through the walls connects the exterior of the osmotic capsule with the interior of the osmotic capsule.

An osmotic device is disclosed for delivering a beneficial agent. The device comprises a wall surrounding a compartment containing an agent, a passageway in the wall connecting the exterior of the device with the compartment, and (a) an agent in the wall or (b) an agent carried on the wall in the wall. The device delivers the agent from the compartment and the wall.
摘要:
A method of forming a dispenser for delivering a beneficial agent to a biological environment. A beneficial agent and an expandable composition are placed in a capsule made of fluid dissolvable material. The capsule is closed and surrounded by a semipermeable wall which is permeable to fluid but not to the beneficial agent. Then a passageway is drilled in the capsule between the exterior and the interior which contains the beneficial agent.
