MEDICAMENT IN A MULTILAYER FORM |
摘要 |
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 are 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 coating made of a copolymer comprising 75 to 95 percent by weight of radically polymerized C<SUB>1</SUB> to C<SUB>4</SUB> 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 coating 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. |
