The present invention provides an improved method of administering a pharmaceutical composition, such as an anesthetic through the skin of a patient without the use of a sharp or needle. This method includes the step of irradiating the stratum corneum of a region of the skin of the patient using a laser. By a selection of parameters, the laser irradiates the surface of the skin precisely to a selectable depth, without causing clinically relevant damage to healthy proximal tissue. A pharmaceutical composition is then applied to the region of irradiation.
La présente invention concerne un procédé amélioré d'administration d'une composition pharmaceutique telle qu'un agent anesthésique dans la peau d'un patient sans utiliser d'aiguille. Ce procédé consiste à irradier la couche cornée d'une zone de la peau du patient à l'aide d'un laser. Par le biais d'une sélection de paramètres, le laser irradie la surface de la peau avec précision jusqu'à une profondeur choisie sans provoquer de lésions importantes du point de vue clinique sur le tissu proximal sain. Une composition pharmaceutique est ensuite appliquée sur la zone irradiée.
