摘要:
The invention refers to a pharmaceutical or nutraceutical composition comprising a core a) comprising an active ingredient and a water-insoluble polymer, a coating layer b) above the core a) comprising a salt of an alginic acid, and a coating layer c) above the coating layer b) comprising an anionic (meth)acrylate copolymer polymerized from a (meth)acrylate monomer mixture comprising 5 75 % by weight in relation to the total weight of the (meth)acrylate monomer mixture of (meth)acrylate monomers with an anionic group, wherein the amount of the water-insoluble polymer in the core a) is 2 to 20 % by weight in relation to the weight of the core a) and the amount of the salt of an alginic acid in the coating layer b) is 5 to 85 % by weight in relation to the weight of the core a) and the amount of the anionic (meth)acrylate copolymer in the coating layer c) is 10 to 75 % by weight in relation to the weight of the core a) and to the coating layer b).
