Abstract
A single-use, disposable inhaler comprising: (1) a housing open at both ends, one end forming an air inlet and the other forming an air outlet, thereby defining an air flow path through the inhaler; and (2) an internal plate spaced above and below the housing, oriented parallel to the axis of the inhaler and parallel to the air flow path. The internal plate comprises a storage cavity formed therein, located near the air inlet, in which a single dose of a pharmaceutically active compound is placed. An individual using the inhaler inhales through the air inlet, creating an air stream which lifts the powder out of the storage cavity, into the air stream, and to the user.
