High-dose epinephrine

Icahn School of Medicine at Mount Sinai · FDA-approved active Small molecule

High-dose epinephrine is a catecholamine that acts as a non-selective adrenergic agonist, stimulating alpha and beta-adrenergic receptors to increase heart rate, blood pressure, and cardiac output.

High-dose epinephrine is a catecholamine that acts as a non-selective adrenergic agonist, stimulating alpha and beta-adrenergic receptors to increase heart rate, blood pressure, and cardiac output. Used for Cardiac arrest (ventricular fibrillation, pulseless ventricular tachycardia, asystole, pulseless electrical activity), Severe hypotension and shock, Anaphylaxis.

Mechanism of action

Epinephrine binds to alpha-1, alpha-2, beta-1, and beta-2 adrenergic receptors throughout the body. At high doses, it predominantly activates alpha-adrenergic receptors, causing vasoconstriction and increased systemic vascular resistance, while also enhancing myocardial contractility and heart rate via beta-1 receptor activation. This results in rapid increases in blood pressure and cardiac output, making it useful in acute cardiovascular emergencies.
