This adrenergic bronchodilator was used to relieve bronchospasm in asthma and COPD by stimulating beta-2 receptors in the lungs to relax airway smooth muscle. It has a relatively short duration of action compared to newer beta-agonists. It has largely been superseded by more selective and longer-lasting bronchodilators.
