Abstract: A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically- responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.

Abstract: An inhalable dry powder formulation containing SAE-CD and an active agent is provided. The formulation is adapted for administration by DPI. The SAE-CD serves as a carrier rather than as an absorption enhancer. The average particle size of the SAE-CD is large enough to preclude (for the most part) pulmonary deposition thereof. Following release from the DPI device, the SAE-CD-containing particles dissociate from the active agent-containing particles in the buccal cavity or throat, after which the active agent-containing particles continue deeper into the respiratory tract. The physicochemical and morphological properties of the SAE-CD are easily modified to permit optimization of active agent and carrier interactions. Drugs having a positive, neutral or negative electrostatic charge can be delivered by DPI when SAE-CD is used as a carrier.

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.
