PROCESS FOR PREPARING A PARTICULATE AND CRYSTALLINE DRUG SUBSTANCE

摘要

A process of preparing a particulate and substantially crystalline drug substance. The process involves suspending a substantially crystalline drug substance in an anti-solvent to give a suspension, homogenising the suspension at elevated pressure to give drug particles that have a mean particle size of less than about 10 μm, and drying the drug particles to remove any residual anti-solvent.
