Answer

Long-acting beta2 agonists

Long-acting bronchodilators are not used for the treatment of acute bronchospasm. In combination with corticosteroids, they are used for the preventive treatment of asthma symptoms.

Salmeterol (Serevent Diskus)

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. It is to be used with inhaled corticosteroids and not as monotherapy.

Formoterol (Perforomist)

Formoterol is a long acting beta2 agonist. By relaxing the smooth muscles of bronchioles in conditions associated with bronchitis, emphysema, asthma, or bronchiectasis, formoterol can relieve bronchospasms. The effects may also facilitate expectoration. It has been shown to improve symptoms and morning peak flows. Adverse effects are more likely when formoterol is administered at high doses or more frequent doses than recommended. To be used with inhaled corticosteroids and not as monothrapy.
