How Salmeterol Works

Salmeterol works by stimulating specific receptors in the lungs known as beta-2 adrenergic receptors. This action helps to relax and open the airways, making breathing easier.

As a long-acting beta-agonist, it provides prolonged relief from symptoms, usually over a 12-hour period.

It is often used in conjunction with inhaled corticosteroids for better management of asthma symptoms.
