Abstract
An aerosol powder delivery device, a method of producing or delivering aerosol particles, a method of making a delivery device, and an inhaler kit are provided. The device can be used to produce an aerosolizable powder by breaking or deagglomerating the aerosolizable powder into aerosol particles for inhalation. The aerosol particles can be produced by mechanically agitating or shaking a hollow device with the aerosolizable powder and a second powder to mechanically break or loosen aerosol particles from the aerosolizable powder. Thus, a small, lightweight, simple, sealed and stable device without complex moving parts, external power sources or heat is provided to aerosolize powder into aerosol particles for transmucosal delivery into a mouth upon inhalation.
