Summary for Patent: 8,367,734

Title:	Stable epinephrine suspension formulation with high inhalation delivery efficiency
Abstract:	A stable suspension aerosol formulation of epinephrine is suitable for administration through inhalation comprising a therapeutically effective amount of epinephrine, hydrofluorocarbon propellant, co-solvent, surfactant, and antioxidant. The suspension aerosol formulation further comprises [pre-] pre-micronized epinephrine suspended in an alcohol/surfactant solution with hydrofluoroalkane propellant. The suspension formulation provides a highly efficient delivery of drug microparticles into the respirable region of patients' lungs and has the following advantages: lower dosage requirement, minimum alcohol content, with less impurities generated during storage, improved efficacy and safety, and exhibits no ozone depleting potential compared to a formulation containing chlorofluorocarbon.
