Answer

Long-acting beta2 agonists

Long-acting bronchodilators are not used for the treatment of acute bronchospasm. They are used for the preventive treatment of nocturnal asthma or exercise-induced asthmatic symptoms, for example. Currently, 2 LABAs are available in the United States: salmeterol (Serevent) and formoterol (Foradil). Salmeterol and formoterol are available as combination products with inhaled corticosteroids in the United States.

Salmeterol (Serevent)

Salmeterol can relieve bronchospasm by relaxing the smooth muscles of the bronchioles in conditions associated with bronchitis, emphysema, asthma, or bronchiectasis. The effect also may facilitate expectoration. Adverse effects are more likely when salmeterol is administered at high doses or more frequent doses than recommended.
