    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.
