  • Patent number: 6669879
    Abstract: A process for producing solid dosage forms by forming a plastic mixture of at least one polymeric binder, at least one active ingredient and, where appropriate, conventional additives, and shaping the plastic mixture to the solid dosage forms using a mold, wherein an agent which modifies the surface properties is applied in finely divided form to the surface of the plastic, mixture during the shaping is described. The agent which modifies the surface properties is preferably a surfactant, a lipophilic compound, an antioxidant, a coloring agent or an agent with antistatic effect and/or lubricant effect.
