    摘要: A device for delivering a powdered medicament by inhalation comprises an air inlet passage having low pressure-drop and low turbulence for stabilizing air flow before aerosolization, a dosing cup in the region of reduced air velocity to delay aerosolization, a high pressure drop throat to generate a high velocity flow, a rapidly expanding diverging passage to create a free jet of air with high turbulence and an outlet passage having large cross-sectional area to control the rate of dissipation of the free jet. The device is simple yet capable of consistently providing uniform and effective powder aerosolization and deagglomeration over a variety of patient inhalation profiles.

    摘要: Inhalation particles incorporating, in an individual particle, a combination of a βhd 2-agonist and a glucocorticosteroid in a predetermined and constant ratio, a process for the preparation thereof and pharmaceutical compositions comprising the inhalation particles. The particles have a narrow particle size distribution and are preferably in the form of spherical crystalline particles with a rough surface. The particles are particularly useful in the treatment of asthma and other respiratory disorders.
