Vasopressin regulates the tonicity of body fluids. It is released from the posterior pituitary in response to hypertonicity and causes the kidneys to reabsorb solute-free water and return it to the circulation from the tubules of the nephron, thus returning the …

Oct 29, 2024 · What is vasopressin? Vasopressin is used to raise blood pressure in adults with life-threatening low blood pressure when other treatments have not worked. Vasopressin may also be used for purposes not listed in this medication guide.

Feb 28, 2025 · Vasopressin, hormone that plays a key role in maintaining osmolality (the concentration of dissolved particles, such as salts and glucose, in the serum) and therefore in maintaining the volume of water in the extracellular fluid (the fluid space that surrounds cells).

Sep 22, 2023 · Vasopressin is a naturally occurring hormone used in the management of several life-threatening conditions, including abnormal bleeding and septic shock.

Vasopressin, also known as arginine vasopressin or antidiuretic hormone (ADH) is a natural substance primarily synthesized in the hypothalamus in the brain. Vasopressin regulates the body's fluid and electrolyte (osmotic) balance, blood pressure, sodium levels and kidney function.

Jul 13, 2024 · Vasopressin: bioactive neuroendocrine nonapeptide; endogenously produced by the magnocellular neurone cell bodies of the paraventricular and supraoptic nuclei of the posterior hypothalamus Skip to content

Sep 24, 2024 · Vasopressin is a naturally occurring hormone produced by a part of the brain known as the hypothalamus. It serves several essential functions, including maintaining the balance of fluids in the body, normalizing blood pressure, and regulating the sleep-wake cycle.

Vasopressin is a peptide hormone used to increase blood pressure in patients with vasodilatory shock who are resistant to fluid and catecholamine therapy. The vasopressive effect of posterior pituitary gland extracts was noted in 1895, while vasopressin itself was not purified until 1951.

Human neurohormone vasopressin (AVP) is synthesized in overlapping regions in the hypothalamus. It is mainly known for its vasoconstricting abilities, and it is responsible for the regulation of plasma osmolality by maintaining fluid homeostasis.

Mammalian vasopressin functions systemically as an antidiuretic and regulator of blood and cardiac flow essential for adapting to terrestrial environments. Moreover, vasopressin acts centrally as a neurohormone involved in social and parental behavior and stress response.
