Mechanism of action

The inhaled corticosteroid reduces airway inflammation and mucus production. The long-acting beta-2 agonist and long-acting muscarinic antagonist work synergistically to relax bronchial smooth muscle through different pathways, providing sustained bronchodilation. This triple combination addresses multiple pathophysiological mechanisms in COPD to improve airflow and reduce exacerbations.
