==Vasopressin==
Vasopressin is a non-catecholamine vasopressor. It is a hypothalamic hormone found in the posterior pituitary. It promotes the renal reabsorption fo water as well as smooth muscle contraction particularly of capillaries and small arterioles. This smooth muscle contraction may lead to decreased blood flow to systems but increased hepatic blood flow. Vasporessin is indicated in patients with vasodilatory shock or ventricular fibrillation. However, possible side effects include vasconstriction and arrhythmias. It should be avoided in patients with vascular disease, history of seizures, heart failure, asthma or pregnant patients.
