FORMOTEROL - HALF LIFE, MECHANISM OF ACTION 
half-life is 10 h.
Inhaled formoterol works like other β₂ agonists, causing bronchodilation by relaxing the smooth muscle in the airway so as to treat the exacerbation of asthma. The long duration of formoterol action occurs because the formoterol molecules initially diffuse into the plasma membrane of the lung cells, and then are slowly released back outside, where they can come into contact with β₂ adrenergic receptors. Formoterol has been demonstrated to have a faster onset of action than salmeterol as a result of lower lipophilicity, and has also been demonstrated to be more potent – a 12 µg dose of formoterol has been demonstrated to be equivalent to a 50 µg dose of salmeterol.
