Summary:Methods for making inhalable composite particles comprising a pharmaceutically-active agent, the method comprising: a) providing composite particles comprising a millable grinding matrix and a solid pharmaceutically-active agent, wherein the pharmaceutically-active agent has an median particle size on a volume average basis between 50 nm and 3 µm; and b) milling the composite particles in a mill without milling bodies for a time period sufficient to produce inhalable composite particles having a mass median aerodynamic diameter between 1 µm and 20 µm are described. L'invention concerne des procédés de fabrication de particules composites inhalables comprenant un principe pharmaceutiquement actif, le procédé comprenant : a) se procurer des particules composites comprenant une matrice de broyage pouvant être broyée et un principe pharmaceutiquement actif solide, le principe pharmaceutiquement actif a une dimension médiane de particule sur une base moyenne en volume entre 50 nm et 3 µm ; et b) broyer les particules composites dans un broyeur sans corps de broyage pendant une période de temps suffisante pour produire des particules composites inhalables ayant un diamètre aérodynamique médian en masse entre 1 µm et 20 µm.
