ABSTRACT:
A composition for use in an aerosol inhaler, the composition comprising an active material, a propellant containing a hydrofluoroalkane (HFA), a cosolvent and further comprising a low volatility component to increase the mass median aerodynamic diameter (MMAD) of the aerosol particles on actuation of the inhaler, filling of an aerosol container and use of the composition for the administration of active materials by inhalation.
