Abstract: A method for treating respiratory disorders by administrating by inhalation an effective amount of a ?2-receptor agonist, an acceptable amount of a corticosteriod, and HFA 134a, to a patient in need thereof, is disclosed. Preferably, the ?2-receptor agonist is salmeterol or a physiologically acceptable salt thereof, and the corticosteriod is fluticasone propionate or a solvate thereof. The combination of salmeterol, fluticasone proprionate, and HFA 134a may lower the risk of cardiac arrhythmias, sudden death, or hypercorticism that are sometimes associated with the simultaneous administration of a ?2-receptor agonist and an anti-inflammatory corticosteroid.
