Abstract
An aerosolization apparatus comprises a housing defining a chamber having an air inlet and an air outlet, wherein the chamber is sized to receive a capsule containing a pharmaceutical formulation. A puncturing member is moveable within the chamber to contact the capsule and to provide an opening in the capsule, and a feedback mechanism provides an indication, such as a tactile indication, to a user when the puncturing member has been moved to a position where it provides the opening into the capsule. When air flows through the inlet, the pharmaceutical formulation is aerosolized and the aerosolized pharmaceutical formulation is delivered through the outlet.
