Used in the management of chronic obstructive pulmonary disease (COPD), this chemical helps relax the muscles in the airways to improve breathing. It is administered via inhalation and provides long-lasting bronchodilation, typically with once-daily dosing. By blocking muscarinic receptors in the lungs, it reduces bronchoconstriction and helps decrease the frequency of COPD symptoms such as wheezing and shortness of breath. It is often part of a maintenance treatment plan and not intended for rapid relief of acute symptoms.
