The invention encompasses a method for making an amorphous solid of a water-insoluble pharmaceutical comprising: (1) dissolving the water-insoluble pharmaceutical in a water-miscible solvent, optionally with water, to make a solution; (2)(i) rapidly mixing the solution with an antisolvent, wherein the antisolvent is water, at low temperature to precipitate an amorphous solid of the water-insoluble pharmaceutical, or (ii) rapidly mixing the solution with an antisolvent, wherein the antisolvent is water, to precipitate an amorphous solid of the water-insoluble pharmaceutical and subsequently cooling to low temperature; and (3) isolating the amorphous solid of the water-insoluble pharmaceutical. In an embodiment of the invention, the rapid mixing is conducted using an impinging jet device.
本发明涵盖一种制备水不溶性药物非晶固体的方法,包括:(1)将水不溶性药物溶解于水亲和性溶剂中,可选地加入水,制成溶液;(2)(i)在低温下将溶液与抗溶剂(抗溶剂为水)快速混合,使水不溶性药物的非晶固体沉淀下来,或(ii)在快速混合溶液与抗溶剂(抗溶剂为水)后,再冷却至低温,使水不溶性药物的非晶固体沉淀下来;(3)分离水不溶性药物的非晶固体。在本发明实施例中,快速混合使用撞击喷嘴装置进行。
