Mechanism of action

Aclidinium is a long-acting muscarinic antagonist (LAMA) that blocks M3 receptors on airway smooth muscle, preventing bronchoconstriction. Formoterol is a long-acting beta-2 agonist (LABA) that stimulates beta-2 receptors to promote bronchodilation. Together, they provide dual bronchodilation through complementary mechanisms, improving lung function and reducing symptoms in obstructive airway disease.
