What is Foradil?

Formoterol (INN) or eformoterol (former BAN) is a long-acting β₂ agonist used in the management of asthma and chronic obstructive pulmonary disease (COPD). It is marketed in four forms: a dry-powder inhaler, a metered-dose inhaler, an oral tablet, and an inhalation solution, under various trade names including Foradil/Foradile (Schering-Plough in the U.S., Novartis rest of world), Forpack Discair (Neutec inhaler), and Oxeze/Oxis. It is also marketed in the combination formulation budesonide/formoterol.

Formoterol is a long-acting β₂ agonist (LABA) that has an extended duration of action (up to 12 hours) compared to short-acting β₂ agonists such as salbutamol, which are effective for 4–6 hours. LABAs such as formoterol are used as "symptom controllers" to supplement prophylactic corticosteroid therapy (e.g., fluticasone). A "reliever" short-acting β₂ agonist (e.g., salbutamol) is still required, since LABAs are not recommended for the treatment of acute asthma.
