Researchers at Fraunhofer ITEM have shown for the first time that drug levels in the lung can be measured directly using particles in exhaled breath. For this breakthrough, Prof. Jens Hohlfeld and Dr. Olaf Holz received the Willi Stahlhofen Award from the International Society for Aerosols in Medicine. The awarded study demonstrates that so-called Exhaled Breath Particles can be used to non-invasively generate pharmacokinetic profiles – a milestone for the development and optimization of inhaled therapies.
