Patent

CA 2218715

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 (I c) 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.

Dispositif (10) d'administration d'agents par électrotransport permettant d'administrer un agent thérapeutique au travers de la peau sans entamer celle-ci, et procédé d'utilisation de ce dispositif. Le dispositif applique un courant d'électrotransport à impulsions, ces impulsions ayant une amplitude supérieure à un niveau critique (Ic) à partir duquel la peau accède à un état où l'efficacité (E) de l'administration par électrotransport est plus élevée. Idéalement, la durée des impulsions électriques appliquées est d'au moins 5 msec, et de préférence d'au moins 10 msec.
