Vasopressin is a non-catecholamine vasopressor. It is a hypothalamic hormone found in the posterior pituitary which promotes renal reabsorption of water as well as smooth muscle contraction particularly of capillaries and small arterioles. This smooth muscle contraction may lead to decreased blood flow to internal body systems but increased hepatic blood flow.
