Vasopressin
Also known as: Arginine Vasopressin, ADH
Overview
Vasopressin is an endogenous peptide hormone involved in water retention, blood pressure regulation, and vasoconstriction. It is used clinically in certain critical care settings and is studied for cardiovascular and renal physiology.
How it works
Acts at V1 receptors on vascular smooth muscle to cause vasoconstriction and at V2 receptors in renal collecting ducts to increase water reabsorption. It also has central roles in osmoregulation, stress response, and social behaviour.
Primary uses
- Vasopressor physiology
- Antidiuretic signalling
- Blood pressure regulation
- Renal water balance
- Critical care treatment context
