Background:

Formoterol is a selective agonist of the β₂-adrenergic receptor (β₂-AR; K_is = 7.58 and 2,630 nM for β₂- and β₁-ARs, respectively).¹It is selective for β-ARs in isolated guinea pig trachea over those in atrial tissue (pD₂s = 9.29 and 6.98, respectively) and has a long duration of action.^2,1Aerosolized formoterol (10 µg/ml, inhaled) prevents the late asthmatic response and eosinophil and macrophage infiltration in bronchoalveolar lavage fluid (BALF), and as well as reduces bronchial reactivity in a guinea pig model of allergic asthma induced by ovalbumin.³Formulations containing formoterol have been used, alone and in combination with other compounds, in the treatment of chronic obstructive pulmonary disease and asthma.^4,5,6
