Abstract

The invention relates to a method for making a pharmaceutical preparation comprising at least two layers, an outer layer B surrounding an inner layer A containing the active agent. The material forming the outer layer is squeezed through a nozzle 10 of the kind whose metering outlet 12 is provided with an axially directed air duct 13. The invention is characterized in that, during the extrusion of the outer layer B, previously made fragments A1, A2, A3. are fed into the air duct 13 of the nozzle, which fragments form the inner layer A and, after the nozzle, are brought into permanent contact with the tube-shaped outer layer B. The band AB which is thereby obtained is cut into fragments AB1, AB2, AB3. of the required size. <IMAGE>
