Vasopressins, conivaptan

A group of nonpeptide antagonists of vasopressin receptors is being investigated for use in patients with hyponatremia or acute heart failure, which is often associated with elevated concentrations of vasopressin. Conivaptan has high affinity for both Vla and V2 receptors. Tolvaptan has a 30-fold higher affinity for V2 than for Vi receptors. In several clinical trials,... [Pg.845]

Several nonpeptidic, orally active vasopressin receptor antagonists have been developed. The dual V1A/V2R antagonist conivaptan is used in the treatment of hyponatraemia and could also become useful for diseases such as congestive heart failure, in which increased peripheral resistance and dilutional hyponatremia both are present [4]. Side effects of conivaptan include headache, injection site reactions, vomiting, diarrhoea, constipation and thirst. [Pg.1277]

Vasopressin receptor antagonists, such as relcovaptan (an antagonist at Vla receptors), lixivaptan and tolvaptan (V2), and conivaptan (mixed V a/V2), are also under development (1). [Pg.521]

Conivaptan hydrochloride (1) represents the first FDA-approved agent for the treatment of hyponatremia to modulate electrolyte-free water reabsorption in the renal collecting ducts by antagonizing the action of AVP on vasopressin receptors. As such, 1 represents a novel approach toward the treatment of hyponatremia that could significantly affect the pharmacotherapy of a range of diseases characterized by abnormal water retention. [Pg.176]

As Of 2009, conivaptan HCl (1) is one of three vasopressin receptor antagonists approved for use in the treatment of hyponatremia worldwide. The U.S. approval of 1 was preceded by the 2006 approval of mozavaptan hydrochloride (2) in Japan. In 2009, tolvaptan (3) joined 1 as an FDA-approved agent for the treatment of hyponatremia. In this chapter, the pharmacological profile and synthesis of conivaptan hydrochloride (1) is examined in detail. [Pg.176]

Due to the dual renal and vascular action of AVP, scientists at Yamanouchi Pharmaceuticals became interested in the identification of dual Vla/V2 vasopressin receptor antagonists, particularly because such agents were anticipated to be of unique utility in the treatment of congestive heart failure (CHF), where aberrant AVP secretion appeared responsible for both the onset of hypervolemic hyponatremia and deleterious increases in vascular resistance.14 The resulting drug discovery program ultimately lead to the identification of conivaptan HCl (1). [Pg.178]

Conivaptan HCl (1) is a potent dual Vla and V2 vasopressin receptor antagonist that increases water excretion without significant electrolyte depletion. [Pg.182]
