Mechanism of action

Umeclidinium is an inhaled anticholinergic agent that selectively antagonizes muscarinic M3 receptors on airway smooth muscle cells. By blocking acetylcholine-mediated bronchoconstriction, it produces sustained bronchodilation and improves lung function in obstructive airway diseases. Its long duration of action (24 hours) allows once-daily dosing.
