    摘要: An electrotransport agent delivery device (10) for delivering a therapeutic agent through intact skin, and a method of operating same, is provided. The device applies a pulsing electrotransport current wherein current pulses have a magnitude above a critical level (Ic) at which the skin is transformed into a higher electrotransport delivery efficiency (E) state. Most preferably the length of the applied current pulses is at least 5 msec and preferably at least 10 msec.

    摘要: An electrotransport agent delivery device for delivering a therapeutic agent through a body surface, and a method for increasing agent delivery efficiency, is provided. The device includes a current controller which delivers a pulsating electrotransport current and peak current density I.sub.max, I.sub.max being greater than a critical current density level I.sub.c above which the body exhibits a non-transitory higher agent delivery efficiency. Methods for increasing electrotransport delivery efficiency (E) of an agent through a body surface by creation of a higher agent delivery efficiency state are also provided.

    摘要: The invention provides a method for adjusting, i.e., varying, the rate of delivery of a therapeutic agent through a body surface from an electrotransport assembly of the type which includes a predetermined, e.g., fixed, output electronic controller and a detachable therapeutic agent source. The method provides a plurality of therapeutic agent sources in which a single parameter or a series of parameters has been varied. The plurality of agent sources are supplied, one at a time, to the controller of the electrotransport assembly, so that together (i.e., source and controller) the agent delivery rate is varied.

    摘要: An electrotransport apparatus using dispersed ion exchange material (19,83) is disclosed. The ion exchange material (19,83) may be dispersed in either the donor electrode assembly (10), the counter electrode assembly (10) or both electrode assemblies. The dispersed ion exchange material (83) comprises mobile ionic species (84-2) and substantially immobile ionic species (P). The dispersed ion exchange material (83, 84-2) interacts with competitive species (86) generated during electrotransport to render those species substantially immobile (87). Electrotransport devices exhibiting reduced polarization are also disclosed.
