Formoterol

3-formylamino-4-Hydroxy-alpha-(N-1-methyl-2-P-methoxyphenethylaminomethyl)benzyl alcohol.hemifumarate

C19H24N2O4 (344.1736)


Formoterol is a long-acting (12 hours) beta2-agonist used in the management of asthma and/or chronic obstructive pulmonary disease (COPD). Inhaled formoterol works like other beta2-agonists, causing bronchodilatation through relaxation of the smooth muscle in the airway so as to treat the exacerbation of asthma.

3-formylamino-4-Hydroxy-alpha-(N-1-methyl-2-P-methoxyphenethylaminomethyl)benzyl alcohol.hemifumarate

C19H24N2O4 (344.1736)


Arformoterol is a bronchodilator. It works by relaxing muscles in the airways to improve breathing. Arformoterol inhalation is used to prevent bronchoconstriction in people with chronic obstructive pulmonary disease, including chronic bronchitis and emphysema. The use of arformoterol is pending revision due to safety concerns in regards to an increased risk of severe exacerbation of asthma symptoms, leading to hospitalization as well as death in some patients using long acting beta agonists for the treatment of asthma.
