MSH: An adrenergic beta-2 agonist that is used as a bronchodilator and tocolytic.,NCI: A short-acting sympathomimetic agent with bronchodilator activity. Fenoterol stimulates beta-2-adrenergic receptors in the lungs, thereby activating the enzyme adenylate cyclase that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increased cAMP concentrations relax bronchial smooth muscle, relieve bronchospasms, and reduce inflammatory cell mediator release, especially from mast cells.
