Abstract
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. In one embodiment, the two portions are each contained in separate compartments of a pouch. In another embodiment, the portions are contained in a single compartment and divided by a barrier. A method of activating the device includes causing the two portions to come into electrical conducting contact with one another to at least partially hydrate one of the reservoirs. This can be accomplished, for example, by either folding the device to bring the two portions into contact with one another or simply by removing the barrier dividing the two portions. In the alternative, the device may include two separate portions which can be brought together to activate the device. In this way, the device is suitable for use to deliver a high dose efficiency, while providing a commercially suitable shelf-life.
