Title (EN) METHOD FOR PARTICLE SIZE REDUCTION
(FR) PROCÉDÉ POUR DIMINUER LA TAILLE DE PARTICULES
Abstract:
(EN) Disclosed herein are embodiments that generally relate to improved methods for the manufacture of dry powders for inhalation, such as powders for use in a dry powder inhaler device. There are disclosed methods for particle size reduction of an active agent using three-dimensional mixing in the presence of coarse carrier particles, and methods of characterizing powders for use in the manufacture of dry powder blends for inhalation.
(FR) Des modes de réalisation de la présente invention concernent de façon générale des procédés d'amélioration de la fabrication de poudres sèches pour inhalation, telles que des poudres destinées à être utilisées dans un dispositif de type inhalateur de poudre sèche. L'invention concerne des procédés permettant de diminuer la taille des particules d'un agent actif en utilisant un mélange tridimensionnel en présence de particules de support grossières, et des procédés de caractérisation des poudres destinées à être utilisées dans la fabrication de mélanges de poudre sèche pour inhalation.
