Used as a selective β2-adrenergic receptor agonist, primarily in veterinary medicine to treat bronchospasm and respiratory conditions in animals. It acts as a bronchodilator, helping to relax smooth muscles in the airways, thereby improving airflow. Commonly administered in livestock and companion animals for the management of asthma-like symptoms and chronic obstructive airway diseases. Its use in humans is limited and largely obsolete due to the availability of more selective and safer alternatives.
