There provided is a soft pelletized drug composition which is easy to handle in the pharmaceutical manufacturing process, free from the risk for irritable reactions in the user, and controllable in the particle size distribution of the drug to be inhaled. The objective soft pelletized drug composition with a mean particle diameter of 100 µm∼1 mm can be produced by the disclosed technology, for example a method which comprises drying a solution or suspension of the drug substance having self-agglomerative properties in a solution of a sugar such as lactose, micronizing the dry mixture, and rolling the resulting finely micronized powder in a rotary drum.
本发明提供了一种软颗粒药物组合物,该组合物在药品生产过程中易于处理,对使用者没有刺激性反应的风险,并且吸入药物的粒径分布可控。目标软颗粒药物组合物的平均颗粒直径为 100 µm∼1 mm,可通过所公开的技术生产,例如,该方法包括在糖如乳糖的溶液中干燥具有自团聚特性的药物溶液或悬浮液,对干燥混合物进行微粉化,并在旋转滚筒中滚动所得到的细微粉末。
