Brethine (terbutaline sulfate) is an oral beta-2 adrenergic agonist bronchodilator approved in 1976 for relief of bronchospasm in chronic obstructive pulmonary disease. It works by stimulating beta-2 receptors on bronchial smooth muscle, increasing intracellular cAMP and producing airway relaxation with measurable improvement in pulmonary function within 60-120 minutes.
