  • Oral osmotic device
    Patent number: 5200194
    Abstract: An osmotic device (10) for delivering a beneficial drug, such as an anti-microbial drug, 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 comprises a thin semipermeable membrane wall (12) surrounding a compartment (13) housing a beneficial agent (14) that has at least some degree of solubility in aqueous biological fluids, e.g., saliva, and a fibrous support material (15) composed of hydrophilic water-insoluble fibers. A passageway (17) in the wall (12) connects the agent 14) with the exterior of the device (10).
