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 کاملVasopressin receptor antagonists in heart failure.
Vasopressin receptor antagonists are a new class of drugs that address the problems of fluid retention, hyponatremia, and renal dysfunction in heart failure. Elevated vasopressin levels in heart failure cause myocardial fibrosis, hypertrophy and vasoconstriction by activating the V1a receptors, as well as water retention and hyponatremia by activating V2 receptors. Antagonism of V1a receptors a...
متن کاملArginine Vasopressin Receptor Antagonists for Heart Failure
eart failure (HF) is among the most common causes of ospitalization, and its incidence will likely increase in an ging population of “survivors” (1). Pharmacological treatent targeted at neurohormonal activation has improved urvival, but mortality remains substantial in patients with F, thus warranting the search for novel therapeutic aproaches. Novel agents under investigation for the treatent...
متن کاملRole of vasopressin antagonists.
Alterations in intracellular calcium homeostasis and cyclic adenosine 3',5'-phosphate likely underlie the increased cell proliferation and fluid secretion in polycystic kidney disease. Hormone receptors that affect cyclic adenosine 3',5'-phosphate and are preferentially expressed in affected tissues are logical treatment targets. There is a sound rationale for considering the arginine vasopress...
