International ClassA61K 009/22Foreign Application Priority Data1991-11-13 IEAbstractA transdermal device for the controlled administration of a drug to the skin comprises a reservoir (12) for the drug and an electric circuit which includes an electrode system (13, 14) which is operable to actively transport the drug in a controlled manner from the reservoir (12) towards the skin for transport therethrough, the skin not being part of the electric circuit, and the drug passing through an electrode (13) of said electrode system (13, 14) during the active transport to the skin. The electrode (13) is disposed between the reservoir (12) for the drug and an optional transit chamber (15). The electrode (13) can be permeable to the drug or the electrode can function as a gate, being permeable to the drug in the open condition and less permeable to the drug in the closed condition. The operation of the gate can be determined by the composition or the structure of the electrode (13). The device achieves drug delivery rates comparable to those achieved with iontophoretic devices.Field of SearchInfrared, visible light, ultraviolet, X-ray or electrical energy applied to body (e.g., iontophoresis, etc.)Bandage, pad, or shield placed on body for sustained treatment thereof CONTROLLED RELEASE THERAPEUTIC DEVICE OR SYSTEM Implanted dynamic device or system Osmotic or diffusion pumped device or system Method of applying or removing material to or from body Transdermal or percutaneous | |
