A formulation for use in an inhaler device comprises carrier particles having a diameter of at least 50µm and a mass median diameter of at least 175µm; fine particles of an excipient material having a mass median aerodynamic diameter of not more than 20µm; and active particles. The formulation has excellent flowability even at relatively high contents of fine particles.
L'invention concerne une formulation à utiliser dans un dispositif d'inhalation, constituée de particules porteuses ayant un diamètre d'au moins 50 µm et un diamètre moyen massique d'au moins 175 µm; de fines particules d'un excipient ayant un diamètre aérodynamique moyen massique n'excédant pas 20 µm, et de particules actives. La formulation présente une excellente aptitude à l'écoulement, même à des teneurs relativement élevées de fines particules.
