Abstract

Verfahren zur Herstellung von festen sphärischen Formkörpern, die mindestens einen pharmazeutischen Wirkstoff homogen in einer Hilfsstoffmatrix dispergiert enthalten, durch Vermischen der Inhaltsstoffe zu einer Schmelze und anschliessender Formgebung, dadurch gekennzeichnet, daß man mindestens einen pharmazeutischen Wirkstoff mit mindestens einem thermoplastisch verarbeitbaren Matrixhilfsstoff zu einer homogenen Schmelze mit einer Viskosität kleiner 5000 mPas verarbeitet, und die Schmelze mit Hilfe einer rotierenden Lochwalze zu Tropfen formt, welche anschliessend durch Abkühlen verfestigt werden.
