Abstract
A solid or semisolid, at least two-phase active ingredient-containing formulation in which there is multiparticulate incorporation of one of the two phases into a matrix of the other phase, and at least one of the phases contains at least one active ingredient, obtainable by introducing particles of one phase into the other phase in a plastic state, and shaping the material while still plastic.
Claims4
A solid or pharmaceutical composition comprising at least two phases, wherein one phase forms a matrix which consists essentially of one or more components selected from the group consisting of homo- or copolymer of N-vinylpyrrolidone, cellulose ether, hydroxyalkylcellulose, celluloseester and an acrylate- or methacrylate containing polymer and which contains at least one pharmaceutically active ingredient in the form of a solid solution and at least one other phase containing at least one active ingredient is homogeneously incorporated in the form of particles into the matrix phase.
