Abstract

La présente invention concerne des poudres de matière active sur le plan pharmaceutique. Le procédé de préparation de ces poudres consiste d'abord à fournir une solution qui contient cette matière active et une fraction à bas point d'ébullition, à expulser ensuite cette solution par un orifice pour former des gouttelettes, puis à permettre à la fraction à bas point d'ébullition de s'évaporer, et enfin, à collecter les particules ainsi formées. On peut utiliser ces poudres dans des poudres médicinales à inhaler.
