摘要: Background Patients with mild asthma frequently have only exercise-induced bronchoconstriction, a symptom of inadequate control asthma. We evaluated the ability montelukast, leukotriene-receptor antagonist, to protect such patients against bronchoconstriction. Methods randomly assigned 110 (age, 15 45 years) and decrease in forced expiratory volume one second (FEV1) at least 20 percent after exercise on two occasions during placebo run-in period receive 10 mg montelukast (54 patients) or (56 once daily bedtime for 12 weeks double-blind study. Treatment was followed by two-week, single-blind washout which all received placebo. Exercise challenges were performed base line; 24 hours dosing 4, 8, 12; end period. The primary point area under curve FEV1 (expressed as change from base-line values) t...
