    摘要: A membrane system comprising an interior wall, a fluid-permeable exterior wall surrounding the interior wall and an internal compartment defined by the membrane system, wherein fluid permeability of the interior wall is responsive to osmolarity of an osmotic core within the internal compartment are disclosed. A controlled release dosage form comprising the membrane system and a process for delivering an osmotically active formulation from an osmotic pump over an extended period of time are also disclosed.

    摘要: Disclosed are oral osmotic dosage forms and methods wherein a semi-permeable membrane of the oral osmotic dosage form includes from about 23 wt % to about 50 wt % of a flux enhancer and from about 0.01 wt % to about 5 wt % of antioxidant, based on the total dry weight of the semi-permeable membrane. Such compositions provide high flux membranes with improved mechanical and transport stability during storage on the shelf.

    摘要: A dosage form that facilitates the controlled release of an active agent at a desired release rate or release rate profile 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 occupied by the osmotic core. The osmotic core includes an active agent composition and a light push layer. A passageway is formed through the bi-layer membrane system and permits expulsion of the active agent composition from the dosage form during operation. The bi-layer membrane system and the osmotic core are formulated and formed to provide controlled release of the active agent included in the active agent composition, while simultaneously facilitating increased loading of active agent within a dosage form of given dimension and increasing the delivery efficiency of such active agent relative to prior osmotic dosage forms including a push layer.
