General Pharmacology. Beta-adrenoceptor agonists (Î²-agonists) bind to Î²-receptors on cardiac and smooth muscle tissues. They also have important actions in other tissues, especially bronchial smooth muscle (relaxation), the liver (stimulate glycogenolysis) and kidneys (stimulate renin release). Beta-adrenoceptors normally bind to norepinephrine released by sympathetic adrenergic nerves, and to circulating epinephrine.
Epinephrine is an alpha-Adrenergic Agonist, and beta-Adrenergic Agonist, and Catecholamine. The mechanism of action of epinephrine is as an Adrenergic alpha-Agonist, and Adrenergic beta-Agonist. The chemical classification of epinephrine is Catecholamines.
