This long-acting bronchodilator is used once daily as a maintenance treatment for chronic obstructive pulmonary disease (COPD) and sometimes asthma, to keep the airways open and reduce breathlessness. It works by blocking muscarinic receptors in the airway smooth muscle, causing the airways to relax and widen. It is delivered via a special inhaler device and is not a rescue medication for sudden breathlessness.
