β-adrenergic agonists, and especially β2-adrenergic agonists, are generally prescribed for all asthmatics as backup medication to anti-inflammatory therapy or, in the case of exercise-induced asthma, as the primary drug. Technological advances have led to the development of increased β2-specific adrenergic agonists of longer duration of action. The effectiveness of β-adrenergic agonists in treating asthma is indisputable. However, the very effectiveness of these drugs causes problems of overuse, and consequent side effects, raising issues such as whether other drugs or other parameters should be preferentially utilized.
