Mechanism of action

Tiotropium blocks muscarinic M3 receptors on airway smooth muscle to provide sustained bronchodilation, while olodaterol activates beta-2 adrenergic receptors to further relax airways. Together, these complementary mechanisms provide dual bronchodilation with improved lung function and symptom control in COPD patients.
