Continued use of a long-acting beta-2 agonist for treatment of asthma may cause down-regulation of the beta-2 receptor with loss of the bronchoprotective effect from rescue therapy with a short-acting beta-2 agonist. After a large study (SMART) found an increased risk of asthma-related deaths in patients receiving the long-acting beta-2 agonist salmeterol, a boxed warning was added to the labeling of all medications containing a long-acting beta-2 agonist. Now the FDA has completed a meta-analysis of 110 asthma treatment studies in 60,954 patients taking any of the long-acting beta-2 agonist...
