Abstract

The invention relates to a process for producing coated solid dosage forms by forming a plastic mixture from at least one thermoplastic physiologically tolerated polymeric binder and at least one active ingredient and extruding the plastic mixture, wherein the extrudate is subsequently treated with at least one liquid or vaporized coating agent, and the coated extrudate is shaped to the required dosage form.
