Aerosol solution formulation for use in an aerosol inhaler which includes at least one active ingredient selected from 20-ketosteroids and quinolinone derivatives, a propellant containing a hydrofluoroalkane, a cosolvent, and a specific amount of a sequestering agent that stabilizes the formulation. By way of example, the stabilizing agent may be phosphoric acid or sulphuric acid.
