Vasopressin and Vasopressin Receptor Antagonists
Vasopressin, a neurohypophyseal peptide hormone, is the endogenous agonist at V1a, V1b, and V2 receptors. The most important physiological function of vasopressin is the maintenance of water homeostasis through interaction with V2 receptors in the kidney. Vasopressin binds to V2 receptor and increases the number of aquaporin-2 at the apical plasma membrane of collecting duct principal cells. Th...
متن کاملHyponatremia, arginine vasopressin dysregulation, and vasopressin receptor antagonism.
Hyponatremia is often associated with arginine vasopressin (AVP) dysregulation that is regulated by the hypothalamo-neurohypophyseal tract in response to changes in plasma osmolality, commonly in patients with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Potentially lethal complications of hyponatremia most frequently involve the central nervous system and include anore...
متن کاملDegradative studies on vasopressin and performic acid-oxidized vasopressin.
Application of the t,echnique of counter-current distribution t,o the purificat,ion of the pressor principle from beef post’erior pituitary glands has afforded preparations with potencies of over 400 pressor units per mg. (1). Analysis of hydrolysates of such preparations for constituent amino acids by chromatography on starch has shown that they contain approximately equimolar amounts of the e...
متن کاملvasopressin and septic shock
septic shock continues to be one of the leading causes of death in the intensive care units. when the shock state persists after adequate fluid resuscitation, vasopressor therapy is required to improve and maintain adequate tissue/organ perfusion in an attempt to improve survival and prevent the development of multiple organ dysfunction and failure. various studies have suggested that exogeno...
متن کاملVasopressin in the ICU.
PURPOSE OF THE REVIEW Vasopressin is one of the most important endogenously released stress hormones during shock. In this review, studies published in the past year that add to our understanding of the use of vasopressin in the ICU are discussed. RECENT FINDINGS Endogenous vasopressin levels are inappropriately low in adults with severe sepsis but not in children with meningococcal septic sh...
