摘要:
The present invention relates to a process for preparing a crystalline micronised particulate of a glycopyrronium salt. The process involves suspending the drug in a water immiscible anti-solvent in which the drug has little or no solubility and micronizing the suspension. The resulting drug particles are physically stable with regard to agglomeration and/or aggregation on storage.
