摘要 |
Pressurized aerosol composition comprising a liquefied hydrofluorocarbon propellant of formula CxHyFz where x is an integer from 1 to 3, y+z=2x+2, and y and z are both at least 1; from 0.01 to 15% w/w of a particulate medicament dispersed in the liquefied hydrofluorocarbon propellant; and from 0.01 to 10% w/w of a fluorinated surfactant which is soluble in the liquefied hydrofluorocarbon propellant.
