Abstract
An apparatus for generating an aerosol of a therapeutic agent and methods of using the same are disclosed. The apparatus comprises a heating element having a surface and a composition coating at least a portion of the heating element surface. The composition comprises a carrier and a therapeutic agent, wherein when the heating element surface is heated to at least the vaporization point of the carrier, the carrier vaporizes and releases the therapeutic agent from the composition as an aerosol. The heating element can be a coiled filament. The therapeutic agent can be a small molecule, a polynucleotide, a polypeptide, or a recombinant virus. The apparatus can be incorporated into a delivery device, such as a metered dose inhaler or an exposure chamber.
