Of the three classes of bronchodilators ({beta}2-adrenergic–receptor agonists, methylxanthines, and anticholinergic agents), the {beta}2-adrenergic–receptor agonists produce the greatest bronchodilation in patients with bronchial asthma.1 {beta}2-Adrenergic agonists are generally preferred both for the relief of acute symptoms2,3 and for the prevention of exercise-induced bronchospasm.4 The recent introduction of long-acting inhaled {beta}2-adrenergic agonists has overcome the principal shortcoming of the previously available drugs of this class, their limited duration of action. However, the possibility of adverse effects with regular use of {beta}2-adrenergic agonists has been raised.5,6,7 In this article I shall review the pharmacology of the {beta}2-adrenergic agonists, examine potential adverse . . .
