| Conivaptan hydrochloride Usage And Synthesis |
| Description | Arginine vasopressin is intimately involved in volume homeostasis, and
elevated levels of arginine vasopressin are responsible for the pathogenesis and
progression of diseases with an imbalance of sodium and water, particularly
congestive heart failure. To restore homeostasis, antagonism of vasopressin
receptors is a practical solution. As such, conivaptan has been developed and
launched as a dual V1a and V2 vasopressin receptor antagonist. As a competitive,
reversible inhibitor of both subtypes, conivaptan can modulate systemic vascular
resistance through the V1a receptor (Ki ? 0.48 nM) distributed in vascular smooth
muscle cells, cardiomyocytes, hepatocytes, and platelets and blocks the renal V2
receptor (Ki ? 3.04 nM) resulting in enhanced diuresis, thereby increasing serum
sodium concentration and reducing total body volume. Currently, the drug is
approved for the management of refractory hyponatremia and potentially lifethreatening
sodium and water imbalance, but it has shown promise as a potential
treatment option for other diseases, such as congestive heart failure, syndrome of
antidiuretic hormone, diabetes insipidus, and liver cirrhosis. | | Description | Conivaptan is an antagonist of the arginine vasopressin (AVP) receptors V1A and V2 (Kis = 0.48 and 3.04 nM for rat liver V1A and kidney V2, respectively). It also competitively inhibits oxytocin binding to rat uterine oxytocin receptors (Ki = 44 nM) but has no effect on AVP binding to anterior pituitary V1B receptors at concentrations up to 100 μM in a radioligand binding assay. Conivaptan suppresses AVP-induced increases in intracellular calcium in vascular smooth muscle cells (VSMCs) in vitro and the pressor response in pithed rats. Conivaptan (0.01-0.3 mg/kg, i.v.) increases urine output and decreases urine osmolality in dehydrated conscious rats in a dose-dependent manner. It also reduces brain edema and blood-brain barrier disruption in a mouse experimental stroke model. | | Chemical Properties | White to Off-White Solid | | Originator | Yamanouchi (Japan) | | Uses | Conivaptan is a non-peptide inhibitor of antidiuretic hormone (vasopressin receptor antagonist). | | Uses | Used in treatment of congestive heart failure. | | Definition | ChEBI: The hydrochloride salt of conivaptan. It is an antagonist for two of the three types of arginine vasopressin (AVP) receptors, V1a and V2, and is used for the treatment of hyponatraemia (low blood sodium levels) cau
ed by syndrome of inappropriate antidiuretic hormone (SIADH). | | Brand name | Vaprisol (Astellas). |
