    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.
