Salmeterol is a long-acting β₂ adrenergic receptor agonist (LABA) used in the maintenance and prevention of asthma symptoms and maintenance of chronic obstructive pulmonary disease (COPD) symptoms.^[2] Symptoms of bronchospasm include shortness of breath, wheezing, coughing and chest tightness. It is also used to prevent breathing difficulties during exercise (exercise-induced bronchoconstriction).^[3]

It was patented in 1983 and came into medical use in 1990.^[4] It is marketed as Serevent in the US.^[5] It is available as a dry-powder inhaler (DPI) that releases a powdered form of the drug. It was previously available as a metered-dose inhaler (MDI) but was discontinued in the US in 2002.^[2]^[6] It is available as an MDI in other countries as of 2020.^[7]
