ReviewState of the art in beta2-agonist therapy: a safety review of long-acting agents.
Despite concerns in the 1970s and 1980s about the safety of short-acting beta2-agonists, it is now generally accepted that these agents, used at appropriate doses, provide safe and effective treatment for asthma symptoms. After their introduction, beta2-agonists with a long duration of action--formoterol and salmeterol--became widely used as maintenance therapy with inhaled corticosteroids (ICS). ⋯ Formoterol produces long-lasting bronchoprotection against exercise-induced bronchoconstriction, even in patients receiving regular maintenance therapy; its fast onset of effect (similar to salbutamol) allows formoterol to be used as a reliever. Clinically the safety of formoterol and salmeterol has been demonstrated in several studies, both with ICS and alone.
