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.
