PharmacologyIsoproterenol is a relatively selective beta2-adrenergic bronchodilator. Isoproterenol is indicated for the relief of bronchospasm associated with chronic obstructive pulmonary disease. The pharmacologic effects of beta adrenergic agonist drugs, including Isoproterenol, are at least in part attributable to stimulation through beta adrenergic receptors of intracellular adenyl cyclase, the enzyme which catalyzes the conversion of adenosine triphosphate (ATP) to cyclic- 3',5'- adenosine monophosphate (c-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.
