A beta-2 adrenergic agonist, such as albuterol or salbutamol, is a bronchodilator that can quickly relieve the symptoms of an asthmatic attack by relaxing the smooth muscle in the airways. Administered as an aerosol spray, it can quickly reach the lungs and provide rapid relief of bronchospasm. Pulmonary surfactant is used to treat respiratory distress syndrome in premature infants, a muscarinic agonist would exacerbate asthma symptoms, histamine would worsen bronchoconstriction, and a beta-2 adrenergic antagonist would block the bronchodilator effects of endogenous adrenaline and exacerbate the symptoms of asthma.
