Vasopressin (medication)

Vasopressin (medication)

Vasopressin (/ˌveɪzoʊˈprɛsɪn/), also known as antidiuretic hormone (ADH), is a medication and naturally occurring neurohypophysial hormone that is used to treat a number of medical conditions.

Etymology

The term "vasopressin" is derived from the Latin vaso meaning "vessel" and pressin meaning "to press", referring to the hormone's vasoconstrictive properties.

Medical uses

Vasopressin is used in the treatment of several conditions including diabetes insipidus, vasodilatory shock, and esophageal varices. It is also used during cardiopulmonary resuscitation (CPR) to increase blood pressure and cardiac output.

Pharmacology

Vasopressin acts on the V1 receptor and V2 receptor, which are G protein-coupled receptors located in various tissues throughout the body. Activation of these receptors leads to vasoconstriction and water reabsorption, respectively.

Side effects

Common side effects of vasopressin include headache, nausea, abdominal pain, and cardiac arrhythmias. In rare cases, it can cause water intoxication due to its antidiuretic properties.
