Efficacy and safety of low-dose fluticasone propionate compared with zafirlukast in patients with persistent asthma.

Abstract
To compare the efficacy and safety of fluticasone propionate and zafirlukast in patients with relatively stable persistent asthma who were previously treated with inhaled corticosteroids and short-acting beta(2)-agonists.A total of 440 patients (> or =12 years of age) previously treated with inhaled corticosteroids (beclomethasone dipropionate or triamcinolone acetonide) and short-acting beta(2)-agonists were included in this randomized double-blind study. After an 8-day run-in period, patients were treated with fluticasone (88 microg) or zafirlukast (20 mg) twice daily for 6 weeks. Outcome measures included pulmonary function (forced expiratory volume in 1 second [FEV(1)], peak expiratory flow [peak flow]), albuterol use, asthma symptoms, withdrawals due to lack of efficacy, and asthma exacerbations. Patients treated with fluticasone (n = 224) experienced greater mean increases in FEV(1) (0.24 L vs. 0.08 L, P <0.001), morning peak flow (30 L/min vs. 6 L/min, P <0.001), and evening peak flow (23 L/min vs. 5 L/min, P <0.001) during the study than did those treated with zafirlukast (n = 216). Fluticasone-treated patients had significantly greater increases in the mean percentages of symptom-free days (22% vs. 8%, P <0.001), rescue-free days (23% vs. 10%, P = 0.002), nights with uninterrupted sleep (<1% vs. -5%, P = 0.006), and fewer asthma exacerbations (1% vs. 6%, P = 0.005). Fewer fluticasone-treated patients were withdrawn due to lack of efficacy (2% vs. 13%, P <0.001).Inhaled fluticasone was more effective than zafirlukast in maintaining or improving asthma control in patients with relatively stable asthma who were switched from low-dose inhaled corticosteroids.
