(±)-Epinephrine is a natural neurotransmitter that is released from the adrenal medulla and activates adrenoceptors (K<sub>i</sub>s = 15, 735, and 3,970 nM for α<sub>1A-</sub>, β<sub>2-</sub>, and β<sub>1-</sub>adrenergic receptors, respectively). Through these receptors, (±)-epinephrine may induce either contraction or relaxation of vascular smooth muscle, depending on adrenoceptor subtype expression. Receptor-mediated actions of (±)-epinephrine are also relevant to blocking anaphylaxis, reversing cardiac arrest, and reducing bleeding in clinical trials.
