    Abstract: A stable crystalline micronized particulate of a glycopyrronium salt may be prepared by 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.

    Abstract translation: 糖基铵盐的稳定的结晶微粉化颗粒可以通过将药物悬浮在水不混溶的抗溶剂中来制备,其中药物几乎不溶解或不溶解并使悬浮液微粉化。 所得到的药物颗粒在储存时的结块和/或聚集方面物理上是稳定的。
