An aerosolization apparatus comprises a body defining an inlet opening, an
outlet opening, and an aerosolization chamber between the inlet opening
and the outlet opening. The aerosolization chamber is adapted to receive
an elongated receptacle, such as a capsule, containing a pharmaceutical
formulation. The elongated receptacle rotates end-over-end about an axis
substantially orthogonal to an axis passing through the outlet opening
when air or gas flows through the body. In another version, the elongated
receptacle rotates end-over-end about an axis substantially orthogonal to
an inhalation direction.
