Mechanism
How Salmeterol works
Selectively stimulates beta-2 adrenergic receptors causing prolonged bronchodilation through increased intracellular cAMP.

Salmeterol Respiratory Pharmacology Guide
Mechanism, indications, adverse effects, kinetics, exam traps, and NBRC-focused guidance for respiratory therapy students and clinicians.
Salmeterol is a long-acting beta agonist that provides prolonged bronchodilation for maintenance treatment of asthma and COPD. Unlike albuterol, salmeterol should not be used for immediate relief of acute bronchospasm. Students commonly confuse LABAs and SABAs, making this a frequent examination topic.
Clinical Pharmacology
