Abstract
Described herein are respiratory drug condensation aerosols and methods of making and using them. Kits for delivering condensation aerosols are also described. The respiratory drug aerosols typically comprise respiratory drug condensation aerosol particles. In some variations the respiratory drug compound is selected from the group consisting of β-adrenergics, methylxanthines, anticholinergics, corticosteroids, mediator-release inhibitors, anti-leukotriene drugs, asthma inhibitors, asthma antagonists, anti-endothelin drugs, prostacyclin drugs, ion channel or pump inhibitors, enhancers, or modulators and pharmaceutically acceptable analogs, derivatives, and mixtures thereof. Methods of treating a respiratory ailment using the described aerosols are also described. In general, the methods typically comprise the step of administering a therapeutically effective amount of respiratory drug condensation aerosol to a person with a respiratory ailment. Methods of forming a respiratory drug condensation aerosol are also described. The methods comprise the steps of vaporizing and condensing a respiratory drug composition.
