Abstract Background To compare the efficacy and safety of budesonide formoterol Symbicort with formoterol Oxis in the treatment of patients with acute asthma who showed evidence of refractoriness to short-acting P2-agonist therapy. Methods In a 3 hour randomized double-blind study a total of 115 patients with acute asthma mean FEVl 40 of predicted normal and a refractory response to salbutamol mean reversibility 2 of predicted normal after inhalation of 400 pg were randomized to receive either budesonide formoterol 320 9 pg 2 inhalations at t -5 minutes and 2 inhalations at 0 minutes total dose 1280 36 pg or formoterol 9 pg 2 inhalations at t -5 minutes and 2 inhalations at 0 minutes total dose 36 pg . The primary efficacy variable was the average FEV 1 from the first intake of study medication to the measurement at 90 minutes. Secondary endpoints included changes in FEV1
