Abstract
A portable air temperature controlling device useful for warming air surrounding an aerosolized drug formulation is described. Warming the air of an aerosol makes it possible to reduce the size of aerosol particles produced by an aerosol generation device. Additionally, warming the air forces the size of the aerosol particles to be in the range required for systemic drug delivery independent of ambient conditions. Smaller particles can be more precisely targeted to different areas of the respiratory tract.
Claims14
An air temperature controlling arrangement for use in conjunction with an aerosol generation device for the delivery of drugs via aerosol, said air temperature controlling arrangement comprising:
- a heating element having a resistance of about 0.5 to 5 ohms, a mass of about 0.5 to 10 grams and a surface area of about 10 cm2 to 150 cm2;
- and
- a channel adapted to fluidly connect said heating element with the aerosol generation device.
