Abstract

Extrudable pharmaceutical mixtures are tableted by a continuous method in which the mixture is extruded and the still deformable extrudate is pressed between two rollers which are driven in opposite directions and possess depressions opposite one another in the roller shell, the form of these depressions determining the tablet shape.
