The authors discuss the preparation of lipophilic drug nanocrystals by controlled crystallisation during freeze-drying (CCDF). In-line Raman spectroscopy was used to monitor the crystallisation of the drug during freeze-drying to elucidate how the size of the drug crystals could be controlled. A three-way nozzle was used to create a spray freeze-drying process suitable for large-scale production.
