Long-acting β-agonists are a pillar of therapy for many patients with asthma because they are the preferred add-on therapy to inhaled corticosteroids. However, a recent meta-analysis documented a substantial increase in severe exacerbations requiring hospital admission and life-threatening asthma exacerbations in patients treated with long-acting β-agonists. A careful evaluation of this meta-analysis raises several concerns about its applicability to current practice. Pivotal trials evaluating the benefit of adding long-acting β-agonists to inhaled corticosteroids were not included. The authors of the current paper call for physicians to continue their usual practice of using long-acting β-agonists as adjunctive therapy, as well as for an independent meta-analysis of individual patients using inhaled corticosteroids and long-acting β-agonists concomitantly.
