Quizplus · Accepted Answer

Isoproterenol is a synthetic compound that acts as a beta-2 adrenergic receptor agonist. It is commonly used in the treatment of bronchospasm (as in asthma), heart block, and other cardiovascular disorders. Epinephrine, on the other hand, is a naturally occurring molecule that acts as both a beta-1 and beta-2 adrenergic receptor agonist.
