Arformoterol: The first nebulized long-acting beta2-adrenergic agonist

February 01, 2007

Bronchodilators play an important role in the management of stable chronic obstructive pulmonary disease (COPD). Although bronchodilators do not prevent the decline in lung function in patients with COPD, their efficacy in improving disease-related symptoms, reducing the frequency and severity of disease exacerbations, and improving patients' quality of life has been demonstrated in clinical trials. Arformoterol, the (R,R)-enantiomer of the selective beta2-agonist formoterol, is a potent, highly specific, nebulized long-acting beta2-adrenergic agonist recently approved by FDA for the long-term maintenance treatment of bronchoconstriction in patients with COPD, including chronic bronchitis and emphysema. In 2 large, 12-week, phase 3 studies, arformoterol demonstrated an efficacy superior to that of placebo and comparable to that of salmeterol in patients with COPD. In these trials, arformoterol was well tolerated, with a safety profile similar to that of other inhaled long-acting beta2-agonists when used at..
