Which is vasopressin antagonist?
Vasopressin receptor antagonists (Vaptans) are a new group of nonpeptide drugs which have been used in various clinical conditions with limited success. Whereas conivaptan is to be administered intravenously, the other vaptans like tolvaptan, lixivaptan, and satavaptan are effective as oral medication.
What do vasopressin receptor antagonists do?
Vasopressin antagonists are drugs that bind to vasopressin receptors (V1A, V1B and V2) and block the action of vasopressin (antidiuretic hormone, ADH), which is a hormone released by the pituitary gland. Vasopressin causes vasoconstriction and increases reabsorption of water by the kidneys.
What are Vaptan drugs?
The vaptans constitute a new class of pharmaceuticals developed for the treatment of the hypervolemic and euvolemic forms of hyponatremia. These agents are nonpeptide vasopressin antagonists that interfere with the antidiuretic effect of the hormone by competitively binding to V(2) receptors in the kidney.
What drugs block vasopressin?
Conivaptan and tolvaptan are currently the only vasopressin receptor antagonists that are commercially available in the United States and FDA-approved for the treatment of euvolemic hyponatremia in hospitalized patients.
