Alpha-adrenergic activity resulting in peripheral vasoconstriction and beta-adrenergic activity leading to inotropic stimulation of the heart and coronary artery vasodilation.

Indications: Cardiogenic shock, unresponsive to fluid resuscitation, significant hypotensive (<70 mm Hg) sates

Contraindications: Hypotensive patients with hypovolemia, pregnancy (relative)
