Vasopressin: Mechanism, Uses, and Clinical Applications in Critical Care
Vasopressin , also known as antidiuretic hormone (ADH), is a vital peptide hormone produced by the posterior pituitary gland. It plays a key role in regulating water balance in the kidneys and maintaining blood pressure through powerful vasoconstrictive effects. In critical care settings, synthetic vasopressin has become an essential tool for managing hypotension, sepsis, and cardiac arrest. This article explores its mechanisms, therapeutic applications, and key considerations for safe use.
