titleOfInvention |
Multilayer dosage forms, which contain active substances and which comprise a neutral core, and an inner and outer coating consisting of methacrylate copolymers and methacrylate monomers |
abstract |
The invention relates to a multilayer dosage form comprised of: a) a neutral core; b) an inner coating consisting of a methacrylate copolymer; c) an outer coating consisting of a copolymer of which 40 to 95% by weight is composed of radically polymerized C 1 to C 4 alkyl esters of acrylic acid or of methacrylic acid and of which 5 to 60% by weight is composed of (meth)acrylate monomers having an anionic group in the alkyl radical. The invention is characterized in that the inner coating is essentially comprised of a methacrylate copolymer, of which at least up to 90% by weight consists of (meth)acrylate monomers with neutral radicals, which, in accordance with DIN 53 787, has a minimum film formation temperature of no higher than 30° C., and which contains the pharmaceutical active substance in bound form. |
