Mechanism of action

Aclidinium is a quaternary ammonium anticholinergic compound that selectively antagonizes muscarinic M3 receptors on airway smooth muscle and mucus glands. By blocking acetylcholine-mediated bronchoconstriction, it produces sustained bronchodilation and reduces mucus secretion. The drug is formulated as a dry powder inhaler for maintenance treatment of chronic obstructive pulmonary disease (COPD).
