Salmeterol is a long-acting beta2-adrenergic receptor agonist drug that is currently prescribed for the treatment of asthma and chronic obstructive pulmonary disease COPD. It is currently available in both dry-powder inhalers (DPIs) and pressurised metered dose inhalers (pMDIs).
It is a long acting beta-adrenoceptor agonist (LABA), usually only prescribed for severe persistent asthma following previous treatment with a short-acting beta agonist such as salbutamol and is prescribed concurrently with a corticosteroid, such as beclometasone. The primary noticeable difference of salmeterol to salbutamol is that the duration of action lasts approximately 12 hours in comparison with 4–6 hours of salbutamol.
When used regularly every day as prescribed, inhaled formoterol decreases the number and severity of asthma attacks. However, it is not for use for relieving an asthma attack that has already started.
