Leukotriene Antagonists as Asthma-Controller Therapy

In the May 5, 2011, issue of the New England Journal of Medicine, Price et al. (N Engl J Med 2011; 364:1695-1707) report on two parallel, multicenter trials that compared the real-world effectiveness of a leukotriene-receptor antagonist (LTRA) with either an inhaled glucocorticoid being used as a first-line asthma-controller therapy, or a long-acting beta-agonist (LABA) being used as an add-on therapy in patients who were already being given inhaled glucocorticoids. The authors assigned patients to 2 years of open-label therapy. After 2 months, the efficacy of the LTRA was equivalent to the use of an inhaled glucocorticoid as first-line controller therapy and to LABA as an add-on therapy. However, equivalence after 2 years was not proven. The two groups did not show a significant difference in either rate of exacerbations or ACQ scores. Is this what you find in your practice?
