Hot-melt extrusion - a pioneering technology at Rottendorf Pharma

Twin Screw Extruder (PresseBox) (Ennigerloh, ) The cleaning validation for the twin screw extruder in the Development & Transfer Center of Rottendorf Pharma GmbH in Ennigerloh has successfully been completed. With this, the complete equipment of the Center which was newly built in 2009 can be used under GMP conditions as well as under FDA conditions.

The already wide range of equipment for the production of clinical trial samples and small-scale batches is therewith extended by another interesting technology. Hot-melt extrusion by means of the twin screw extruder is particularly suited for improving the solubility and the bioavailability of poorly soluble APIs. Bruno Buss, Director of Development & Transfer is convinced that Rottendorf will be able to build on this in the future: “It is planned to buy further auxiliary equipment for the twin screw extruder in order to better be able to respond to our customers’ requirements.”

Rottendorf’s offer in the field of development and transfer covers in addition to special technologies such as hot-melt extrusion, hot-melt granulation and pelletizing also all standard technologies for the production of solid forms. Laboratory-scale lots below 1 kg as well as stability batches and clinical trial batches from 15 kg up to 150 kg can be produced.
