Abstract:
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.
