Abstract

A process for the solvent-free and mastication-free production of a self-adhesive composition which is based on SBC and comprises a pharmaceutically active substance, in a continuously operating apparatus which comprises a feeding section and a compounding section. The SBC is added to the feeding section and the pharmaceutically active substance is added to the feed section and/or the compounding section, and the composition is homogenized in the compounding section.
