Randomized Controlled Trial Multicenter Study Clinical Trial
Oral montelukast, inhaled beclomethasone, and placebo for chronic asthma. A randomized, controlled trial. Montelukast/Beclomethasone Study Group.
Oral leukotriene receptor antagonists have been shown to have efficacy in chronic asthma. ⋯ Although beclomethasone had a larger mean effect than montelukast, both drugs provided clinical benefit to patients with chronic asthma. This finding is consistent with the use of these agents as controller medications for chronic asthma.
