摘要 |
<p>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 formi ng 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, where in the coated composition is in the form of a film less than 10 .theta. thick; and, (b) allowing the vapor to cool, thereby forming an aerosol, which is us ed 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 vapo r to cool, thereby forming an aerosol, which is used in inhalation therapy.</S DOAB></p> |
