Study Notes

Norepinephrine (Levophed) Overview

Norepinephrine, also known as Levophed, is a sympathomimetic drug.
Administered via intravenous (IV) piggyback route.

Drug Action

Acts primarily as an alpha adrenergic agonist, with some beta-1 adrenergic agonist properties.
Induces vasoconstriction, significantly increasing vascular resistance.
Produces inotropic effects, enhancing cardiac contractility, particularly affecting the renal and mesenteric circulation.

Pharmacokinetics

Rapid onset of action, typically within 1 to 3 minutes after administration.
Effects last for approximately 5 to 10 minutes.

Indications for Use

Used in the treatment of severe cardiogenic shock, improving hemodynamic status.
Effective for managing neurogenic shock by stabilizing blood pressure.
Provides inotropic support in critically ill patients.
Indicated for hemodynamically significant hypotension (hTN) to restore proper circulation.
