<unk> , also known as<unk> , is a long-acting β2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD).<unk>  has an extended duration of action (up to 12 h) compared to short-acting β2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h. LABAs such as<unk>  are used as "symptom controllers" to supplement prophylactic corticosteroid therapy. A "reliever" short-acting β2 agonist (e.g., salbutamol) is still required, since LABAs are not recommended for the treatment of acute asthma. It was patented in 1972 and came into medical use in 1998. It is also marketed in the combination formulations budesonide/formoterol and mometasone/formoterol.
