<p>The invention relates to a medicament in a multilayer form, containing a) a core with a pharmaceutical agent, b) an inner coating, 50 to 95 percent by weight of which arc composed of a (co)polymer comprising 95 to 100 percent by weight of radically polymerized vinylic monomers with neutral side groups and 0 to 5 percent by weight of monomers with anionic side groups, c) an outer coaling made of a copolymer comprising 75 to 95 percent by weight of radically polymerized C1 to C4 alkyl esters of acrylic acid or methacrylic acid and 5 to 25 percent by weight of (meth)acrylate monomers with an anionic group in the alkyl radical. Said medicament further contains 5 to 30 percent by weight of common pharmaceutical auxiliaries, particularly emollients. The inventive medicament is characterized in that the inner coaling contains 5 to 50 percent by weight of common pharmaceutical auxiliaries which are no expanding agents while the amount of expanding agents provided is less than 5 percent by weight.</p> |
