APPARATUS AND METHOD FOR AEROSOLISING A POWDER PHARMACEUTICAL COMPOSITION

摘要

The invention provides exemplary methods and apparatus for aerosolizing a pharmaceutical formulation contained within a receptacle. In one method, a metered amount of a pressurized gas is provided, with the pressurized gas previously being in equilibrium with a liquid. The metered gas is released to create a high pressure gas stream. The high pressure gas stream is flowed through an aerosolization mechanism to extract the pharmaceutical formulation from the receptacle and to disperse the pharmaceutical formulation within the gas stream to form an aerosol.
