Bronchodilators are essential therapeutic agents indicated for patients with lower-than-optimal airflow through the lungs due to obstructive airway conditions. The primary classes include beta-2 agonists and anticholinergic agents, both of which act on the smooth muscle of the bronchioles to facilitate airway dilation. These medications are widely used in the management of asthma and chronic obstructive pulmonary disease, either to rapidly reverse acute symptoms or to improve baseline lung function in chronic disease.
