Which type of drugs does tiotropium belong to?

Tiotropium is classified as a bronchodilator specifically categorized as a long-acting anticholinergic agent. It works by inhibiting the action of acetylcholine on muscarinic receptors in the airways, leading to bronchodilation. This effect is particularly beneficial for individuals with chronic obstructive pulmonary disease (COPD) and asthma, as it helps open the airways and improve airflow, making breathing easier.

The primary function of tiotropium is to relax the muscles around the airways, which is a characteristic feature of bronchodilators. This makes it effective for maintaining bronchodilation over an extended period, differentiating it from short-acting bronchodilators that may require more frequent dosing. Understanding tiotropium's role as a bronchodilator is crucial for managing respiratory conditions effectively.
