    摘要: An osmotic device (10) for delivering an ergot alkaloid into the mouth of a human patient is disclosed. The device (10) has a size and shape adapting it to be comfortably retained in the mouth for extended periods of time. The device (10) comprises a wall (12) surrounding a compartment (13) housing a layer of an ergot alkaloid (14) and a layer (16) of a fluid swellable, hydrophilic polymer. A passageway (17) in the wall (12) connects the ergot alkaloid (14) with the exterior of the device (10). The wall (12) is permeable to the passage of aqueous biological fluid but substantially impermeable to the passage of the hydrophilic polymer (16). In one embodiment the ergot alkaloid (14) has a different color than the hydrophilic polymer (16). The wall (12) is sufficiently translucent to permit the patient to see the amount of ergot alkaloid (14) remaining to be delivered. Marking lines (19) may be provided on the wall (12) indicating the amount of ergot alkaloid (14) which has been delivered and/or the amount remaining to be delivered.

    摘要: A method is disclosed for delivering a drug substantially-free of rapid precipitation from an osmotic device. The osmotic device comprises a semipermeable wall surrounding a compartment housing (1) a drug that exhibits limited solubility under neutral and acid conditions, and (2) a compound capable of evolving carbon dioxide in the presence of an acid in the environment of use. The method comprises, (a) imbibing fluid through the wall into the compartment at a rate determined by the permeability of the wall and the osmotic pressure gradient across the wall, (b) forming in the compartment a basic solution containing drug and compound, which solution is delivered from the compartment through the passageway, (c) reacting the compound with the acid in the environment at the device-environment interface for evolving carbon dioxide, thereby, (d) providing an effervescent suspension in the environment that delivers the drug in a finely dispersed form to the environment of use over time. Also, a composition is disclosed comprising the drug and the compound.
