FIELD: medicine.
SUBSTANCE: invention relates to medicine, particularly to a method for the preparation of crystalline micronized particulate of the glycopyrronium salt. Said method comprises suspending the drug in a water immiscible anti-solvent in which the drug has little or no solubility and micronizing the suspension.
EFFECT: resulting drug particles are physically stable with regard to agglomeration and/or aggregation during storage.
