ABSTRACT:
The present invention relates to an apparatus for producing solid active ingredient-containing forms from an active ingredient-containing formulation which comprises at least one polymeric binder. The apparatus according to the invention has at least one extruder1for continuous plastication of the formulation and at least two injection units2which are provided separate from one another, each of which is connected to the extruder1, and through which the formulation can be injected into at least one mold3. In the process according to the invention for producing solid active ingredient-containing forms from an active ingredient-containing formulation which comprises at least one binder, the active ingredient-containing formulation is continuously plasticated, the plasticated formulation is fed into an injection unit21, and the formulation present in this injection unit21is injected into a mold3, and plasticated formulation is fed into another injection molding unit22, and the formulation present in the other injection molding unit22is injected into the mold3or another mold.
