Greater patient input into drug product design could significantly improve outcomes and save health systems millions, by reducing medication-related errors and unnecessary hospitalisations. This was the take-away message of a talk by Professor Sven Stegemann of the Technical University of Graz, Austria, delivered to Semalytix employees on July 8. Prof. Stegemann is professor for patient-centric drug design and has a long history working for pharmaceutical companies in drug development and manufacturing.
