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： A transdermal drug delivery device (20) is provided having both an active drug reservoir (24) and a passive drug reservoir (26). Drug is actively delivered by iontophoresis from the active drug reservoir (24) by an electric field generated by a power source (21). Simultaneously, drug is delivered from passive reservoir (26) by passive (i.e., non-electrically assisted) diffusion. In one embodiment, the passive drug reservoir (26) is electrically insulated from the active drug reservoir (24). In a second embodiment, both the active and the passive drug are contained in the same reservoir (34). In the second embodiment, the active drug is ionizable while the passive drug is non-ionizable. Most preferably, the active drug is an ionizable form (i.e., a salt form) of the passive drug.

摘要： A dry-state iontophoretic drug delivery device (10, 70, 80) is provided. The device has drug and electrolyte reservoirs (15, 16) which are initially in a non-hydrated condition. A liquid-containing pouch (21, 22) is provided. In certain embodiments the liquid is contained in breakable capsules within the pouch. Water or other liquid can be released from the capsules in the pouch by squeezing or flexing the pouches (21,22). Alternatively, the liquid can be released from the pouches (21,22) using pouch piercing pins (36,37). The liquid released from the pouches (21,22) hydrates the drug and electrolyte reservoirs (15, 16) and activates the device. In another embodiment, the device (20, 20a) has liquid-containing gel layers (31,32) which are initially separated from their respective electrode assemblies (8, 9). Liquid-wicking pathways (27,28) are provided to carry the liquid from the gel layers (31,32) to the drug and electrolyte layers (15, 16).
