Vasopressors are medications that causes vasoconstriction; some of them have additional inotropic effect. By maintaining end-organ perfusion; the role of vasopressors remains critical to prevent irreversible organ injury and failure, and their use is usually accompanied by fluid resuscitation for adequate patient outcomes. Vasopressor agents are used clinically in the treatment of arterial hypotension in shock states. Shock is best defined as inadequate blood flow to meet the metabolic needs of the tissues. The most common reasons for shock are the cardiac output is low relative to the global demand, despite increased O2 extraction by the tissues; or perfusion pressure is inadequate such that blood flow distribution to metabolically active tissues is inadequate, despite an otherwise adequate cardiac output.
