Patent

CA 2201725

An electrotransport drug-containing composition is provided. The composition includes a drug to be delivered through a body surface (e.g., skin) of a patient, and a permeation enhancer which is solid or semisolid at temperatures typically encountered during storage of pharmaceuticals (e.g., temperatures up to at least about 25 °C). The composition of the invention may be applied from a device (10) suitable for electrotransport delivery. A method for increasing electrotransport agent delivery rate and reducing body surface resistance relies on applying the composition of the invention to the body surface, and applying an electric current through the composition and the body surface.

L'invention se rapporte à une composition renfermant un médicament destinée à être administrée par électrotransport. La composition comprend un médicament destiné à être administré à travers une surface du corps (p.ex. la peau) d'un patient, et un activateur de pénétration qui est solide ou semi-solide à des températures généralement utilisées pour le stockage de produits pharmaceutiques (p. ex. à des températures s'élevant à au moins environ 25 DEG C). La composition de l'invention peut être appliquée à partir d'un dispositif (10) convenant à l'administration par électrotransport. Un procédé destiné à augmenter la vitesse d'administration par électrotransport d'un agent et à réduire la résistance de la surface du corps consiste à appliquer la composition de l'invention sur la surface du corps et à appliquer un courant électrique dans la composition et la surface du corps.
