Abstract
Système d'administration pour le tube digestif, comportant un médicament associé à une matière de noyau, le noyau étant entouré d'une matière d'enrobage non hydrosoluble ou relativement peu hydrosoluble dans laquelle est noyée une matière particulaire non hydrosoluble. Lorsque le dispositif d'administration pénètre dans le tube digestif, la matière particulaire absorbe du liquide de manière à former des passages reliant le noyau renfermant le médicament à l'extérieur du dispositif d'administration. Ces passages permettent de libérer le médicament dans le tube digestif à partir du noyau. On peut déterminer avec précision l'endroit où le médicament sera libéré en modulant les paramètres du dispositif, à savoir, par exemple, la matière de noyau, la matière servant d'excipient dans l'enrobage, et la matière particulaire. On a également prévu un procédé pour la mise en oeuvre du dispositif dans le traitement des maladies par libération de médicaments dans le tube digestif, dans un endroit précis et à un instant précis.
