Mechanism of action

LABAs activate beta-2 adrenergic receptors, triggering a cascade that increases intracellular cAMP and leads to smooth muscle relaxation in the airways. This produces a prolonged bronchodilatory effect lasting 12-24 hours, making them suitable for maintenance therapy in chronic respiratory diseases. They are typically combined with inhaled corticosteroids to reduce exacerbations and improve lung function.
