vasoaktiven
Vasoactive, or vasoaktiven in Swedish, describes substances that influence vascular tone by acting on the smooth muscle of blood vessels. Vasoactive agents can constrict or dilate vessels, thereby changing systemic and regional blood flow and blood pressure. They are used in medicine to manage conditions such as shock, hypertension, and perioperative hemodynamics.
Mechanisms vary by substance. Many vasoactive drugs act on receptors in vascular smooth muscle or the endothelium,
Endogenous vasoactive mediators include norepinephrine, epinephrine, angiotensin II, vasopressin, and endothelin-1. These substances regulate baseline vascular
Pharmacologic agents are grouped into vasopressors, which raise blood pressure by increasing vascular tone, and vasodilators,
Clinical use requires careful monitoring of blood pressure, heart rate, and organ perfusion, with attention to
