This selective long-acting beta2-adrenergic receptor agonist causes relaxation of bronchial smooth muscle and has 2-fold greater potency than racemic formoterol. Arformoterol was approved on October 6, 2006, for the long-term, twice-daily (morning and evening) maintenance treatment of bronchoconstriction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.
