A multilayer preparation in the form of films of hydrophilic polymers for rapid release of substances present in the film layers into liquid surroundings is characterized in that adjacent layers differ from one another in that in each case one layer is soluble in a nonaqueous solvent in which the respective adjacent layer is insoluble or only slightly soluble.
La présente invention concerne une préparation multicouche, se présentant sous forme de film, constituée de polymères hydrophiles et permettant la libération rapide de substances contenues dans les couches du film, dans un environnement fluide. Cette préparation est caractérisée en ce que des couches voisines se différencient l'une de l'autre de par le fait qu'une couche respective est soluble dans un solvant non aqueux, dans lequel la couche voisine respective n'est pas ou est peu soluble.
