Abstract: Solid drug forms are produced by mixing and melting at least one pharmacologically acceptable polymeric binder and at least one pharmaceutical active ingredient, with or without conventional pharmaceutical additives, in the absence of a solvent to give a plastic mixture and shaping the mixture to the required drug form by extrusion, where the shaping takes place in two steps, with the extrudate being broken into shaped articles in a first step, and these shaped articles being rounded off in a second step in the plastic state.

Abstract: The invention concerns a method of producing multi-layer medicaments in solid form for oral or rectal administration. At least two substances, which each comprise a thermoplastic, pharmacologically acceptable polymer binder which is soluble or can swell in a physiological environment, at least one of the substances comprising a pharmaceutical active substance, are coextruded and the coextruded multi-layer material is shaped to form the desired medicament.
