Abstract

Cette invention se rapporte à un dispositif d'apport de médicament avec imbibition de fluide, qui sert à amener avec un retard initial une formulation d'un agent actif dans un milieu fluide d'utilisation, cette période de retard initial avant le démarrage ou l'activation du dispositif étant d'une durée prédéterminée. L'apport de la formulation de l'agent actif à partir du dispositif distributeur est prolongé jusqu'à ce que pratiquement toute la formulation de l'agent actif soit distribuée à la suite de l'expansion d'un agent d'expansion dans la chambre d'apport de l'agent actif.
