Formoterol, also known as eformoterol, is a long-acting β2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol 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. Formoterol has a relatively rapid onset of action compared to other LABAs, and is effective within 2-3 minutes.[2] The 2022 Global Initiative for Asthma report [3] recommends a combination formoterol/inhaled corticosteroid inhaler as both a preventer and reliever treatment for asthma in adults. In children, a short-acting β2 adrenergic agonist (e.g., salbutamol) is still recommended.
It was patented in 1972 and came into medical use in 1998.[4] It is available as a generic medication.[5] It is also marketed in the combination formulations budesonide/formoterol and mometasone/formoterol.

Transcription
Side effects
In November 2005, the US Food and Drug Administration (FDA) released a health advisory alerting the public to findings that show the use of long-acting β2 agonists could lead to a worsening of wheezing symptoms in some patients.[6]
Nowadays, available long-acting β2 agonists include salmeterol, formoterol, bambuterol, and sustained-release oral salbutamol.
Combinations of inhaled steroids and long-acting bronchodilators are becoming more widespread – combination preparations include fluticasone/salmeterol and budesonide/formoterol.
Mechanism of action
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.
