Abstract: A pharmaceutical composition that is suitable for inhalation is disclosed, thus ensuring an effective treatment of the lungs. For this purpose, an aerosol composition is believed to be suited. The aerosol preparation comprises a stabilized suspension of sodium cromoglycate from which the active substance is favorably absorbed in the lungs after inhalation. In the aerosol preparation, 1 to 4% by mass of sodium cromoglycate is suspended in a mixture of propellants comprising 0.3 to 2.0% by mass of a dispersing agent consisting of oleyl oleate.

Abstract: The present invention relates to an aerosol composition free of propellant gas, comprising nitroglycerin as active ingredient. The composition according to the invention is composed of:0.1 to 4% by weight of nitroglycerin,51 to 90% by weight of a C.sub.2-4 aliphatic alcohol (component A),10 to 49% by weight of a polyalkyleneglycol comprising 2 or 3 carbon atoms in the alkylene moiety (component B.sub.1) and/or a C.sub.2-8 alcohol comprising two or three hydroxy groups (component B.sub.2)optionally together with one or more pharmaceutically acceptable carriers and/or diluents.
