  • Drug-dispensing device and method
    Patent number: 4207890
    Abstract: A drug-dispensing device and method for controlled and prolonged internal administration of medicaments to warm-blooded animals comprising an outer polymer envelope containing an expanding agent, drug metering means, and the drug itself. The outer polymer envelope is permeable to both the drug and body fluids and expands when the expanding agent is contacted by body fluids when the device is in the environment of use (e.g., the stomach). This expansion maintains the device in the environment of use while the drug is administered by the metering means.
