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.

Claim (Index 13):
A multilayer dosage form, comprising\n a) a neutral core; b) at least one inner layer comprising at least a portion of a pharmaceutically active substance and a methacrylate copolymer, wherein said methacrylate copolymer comprises at least 90% by weight of (meth)acrylate monomers having neutral radicals and has a minimum film-forming temperature as specified in DIN 53 787 not exceeding 30\u00b0 C., and wherein the pharmaceutically active substance is in bound form; and c) an outer layer comprising Eudragit\u00ae L 30D; wherein values for the percentage release of the pharmaceutically active substance from the multilayer dosage form in a hypotonic and an isotonic release medium based on phosphate buffer pH 6.8 do not differ from one another at any time in the period from 1 to 5 hours by more than 10%.
