description This invention relates to pressurised aerosol compositions, in particular compositions of inhalation medicaments. Pressurized aerosol composition for administration by inhalation comprising a liquefied hydrofluoroalkane, a powdered medicament dispersed therein, and a suspending agent comprising a polymer soluble in the liquefied hydrofluoroalkane which is selected from polymers including recurring amide containing structural units, copolymers of amide containing units and carboxylic acid ester units, polyvinylacetate and acrylic acid/methacrylic acid ester copolymers.
