Self-dispersing Liquids as Aerosol Drug Carriers

Inhaled medications are often used to treat lung diseases such as cystic fibrosis. We are performing this study to determine whether inhaled medications dissolved in surfactant-based solutions will distribute more evenly throughout the lungs when compared to standard saline-based solutions. We think that inhaling medication that is in a surfactant-based liquid will result in more medication reaching partially blocked parts of the lung. This study will use a special nuclear medicine test called an aerosol deposition scan to compare how a drug spreads in the lung using a surfactant-based aerosol compared to a saline-based aerosol.
