Mechanism of action

Indacaterol activates beta-2 adrenergic receptors on bronchial smooth muscle, leading to increased intracellular cAMP levels and smooth muscle relaxation. This produces sustained bronchodilation lasting 24 hours or longer, making it suitable for once-daily maintenance therapy in obstructive airway diseases. The drug's long duration of action is attributed to its high lipophilicity and depot formation in lung tissue.
