Why would epinephrine not be the first-choice bronchodilator for animals?
What will be an ideal response?
In addition to being a bronchodilator, epinephrine stimulates receptors in the heart (causing tachycardia) and causes vasoconstriction of the peripheral blood vessels. Better choices would be terbutaline or albuterol, which stimulate receptors in the bronchi and only minimally stimulate receptors in the heart.
