A user activated iontophoretic device of the present invention includes an electrode assembly, an electrode reservoir and at least one drug reservoir. The device is divided or otherwise separated into at least two portions, with one portion containing the electrode reservoir and the other containing the drug reservoir, which may include a medication in a dry form. The electrode reservoir and the drug reservoir are sealingly separated by a barrier, which can be removed to bring the reservoirs into fluid conducting contact with one another. A method of activating the device includes causing the two portions to come into fluid conducting contact with one another to at least partially hydrate one of the reservoirs. This can be accomplished by removing the barrier dividing the two portions. In this way, the device is suitable for use to deliver a drug which has limited stability in an aqueous solution. |
