    Abstract: The present invention relates to the inhalation delivery of aerosols containing small particles. Specifically, it relates to a method of forming an aerosol for use in inhalation therapy. In a method aspect of the present invention, a method of forming an aerosol for use in inhalation therapy is provided. The method involves the following steps: (a) heating a substrate coated with a composition comprising a drug at a rate greater than 1000 °C/s, thereby forming an vapor; and, (b) allowing the vapor to cool, thereby forming an aerosol, which is used in inhalation therapy. In another method aspect of the present invention, a method of forming an aerosol for use in inhalation therapy is provided. The method involves the following steps: (a) heating a substrate coated with a composition comprising a drug to form a vapor, wherein the coated composition is in the form of a film less than 10 µ thick; and, (b) allowing the vapor to cool, thereby forming an aerosol, which is used in inhalation therapy. In another method aspect of the present invention, a method of forming an aerosol for use in inhalation therapy is provided. The method involves the following steps: (a) heating a substrate coated with a composition comprising a drug to form a vapor in less than 100 milliseconds, wherein the vapor has a mass greater than 0.1 mg; and, (b) allowing the vapor to cool, thereby forming an aerosol, which is used in inhalation therapy.

    Abstract: Disclosed is a method and device for rapid heating of a coated substance which preferably includes a drug to vaporize for inhalation therapy. A device (10) in accordance with the present invention preferably includes a substrate (20) which has an interior surface (20a) surrounding an interior region and an exterior surface (20b) upon which the coated substance (15) is to be adhered. Though the substrate is preferably metallic, it does not need to be. A combustible element (16a.16b) is placed in the interior region of the substrate and a spark or resistance igniter is connected to the combustible element. The igniter is for initiating oxidation of the combustible element. Preferably, the coated substance is vaporized inside of a housing (30) to allow the vaporized drug to aerosolize and be inhaled by a user.
