NCIt definition : A synthetic catechol compound and potent beta adrenergic agonist with peripheral vasodilator,
bronchodilator, and cardiac stimulating properties. Isoproterenol exerts its effect
on the beta-1 adrenergic receptors in the myocardium, thereby increasing heart rate
and cardiac output. In addition, isoproterenol acts on beta-2 adrenergic receptors
in bronchiolar and vascular smooth muscle, thereby causing smooth muscle relaxation.;
