Use of vasopressors and inotropes - UpToDate
Dec 8, 2023 · Vasopressors are a powerful class of drugs that induce vasoconstriction and thereby elevate mean arterial pressure (MAP). Vasopressors differ from inotropes, which increase cardiac contractility; however, many drugs have both vasopressor and inotropic effects.
Inotropes and Vasopressors - StatPearls - NCBI Bookshelf
Feb 19, 2023 · Vasopressors and inotropes are medications used to create vasoconstriction or increase cardiac contractility, respectively, in patients with shock. The hallmark of shock is decreased perfusion to vital organs, resulting in multiorgan dysfunction and eventually death.
Vasopressors: Types, Purpose and Side Effects - Cleveland Clinic
A vasopressor is a drug that healthcare providers use to make blood vessels constrict or become narrow in people with low blood pressure. Often, these are people in shock who are unable to get enough blood to their vital organs.

Feb 20, 2020 · Vasopressin may preferentially cause vasoconstriction of post-glomerular arterioles in the kidney, causing improvement in renal function. It may cause some pulmonary vasodilation, which can be helpful in the context of pulmonary hypertension.
Inotropes, vasopressors and other vasoactive agents
Nov 3, 2020 · OVERVIEW. Vasoactive agents include the following: inotropes are agents that increase myocardial contractility (inotropy) — e.g. adrenaline, dobutamine, isoprenaline, ephedrine. vasopressors are agents that cause vasoconstriction leading to increased systemic and/or pulmonary vascular resistance (SVR, PVR) — e.g. noradrenaline, vasopressin ...
Inotropes and Vasopressors: Doses, indications, contraindications …
Vasopressors induce vasoconstriction and increase mean arterial pressure (MAP). Inotropes increase cardiac contractile force (contractility). Several endogenous and synthetic agents exist and are frequently combined to achieve the desired hemodynamic outcome.
A Guide to the Use of Vasopressors and Inotropes for Patients in …
Apr 13, 2024 · Shock is a life-threatening circulatory failure that results in inadequate tissue perfusion and oxygenation. Vasopressors and inotropes are vasoactive medications that are vital in increasing systemic vascular resistance and cardiac contractility, respectively, in patients presenting with shock.
Pharmacotherapy Update on the Use of Vasopressors and Inotropes in the ...
Nov 28, 2014 · This classification highlights key similarities and differences with respect to pharmacology and hemodynamic effects. Vasopressors include pure vasoconstrictors (phenylephrine and vasopressin) and inoconstrictors (dopamine, norepinephrine, and …
