ABSTRACT:
This invention relates to a pharmaceutical aerosol formulation containing a particulate medicament which is salmeterol or a physiologically acceptable salt or solvate thereof end 1,1,1,2-tetrafluoroethane as propellant, which formulation is free of surfactant or has less than 0.0001 % w/w surfactant based on the weight of medicament. The formulation may contain a further particulate medicament which is salbutamol, beclomethasone dipropionate or a physiologically acceptable salt or solvate thereof. A method of treating respiratory disorders which comprises administration by inhalation of an effective amount of the pharmaceutical aerosol formulation is also described.
