  • Volume efficient controlled release dosage form
    Publication number: 20030185888
    Abstract: The present invention includes a dosage form that facilitates the controlled release of an active agent at a desired release rate or release rate profile. In each embodiment, the dosage form of the present invention includes a bi-layer membrane system and an osmotic core. The bi-layer membrane system includes a semipermeable membrane and an osmosensitive membrane and forms an internal compartment that is occupied by the osmotic core. The osmotic core of the dosage form of the present invention includes and active agent composition and a light push layer. The dosage form of the present invention additionally includes a passageway that is formed through the bi-layer membrane system and permits expulsion of the active agent composition from the dosage form during operation.
