Official title:
Effect of Vasopressin Antagonism on Renal Sodium and Water Handling and Circulation During Inhibition of the Nitric Oxide System in Healthy Subjects
The purpose of this study is to investigate the effect of tolvaptan on renal water, sodium and potassium excretion, plasma concentration of vasoactive hormones,central blood pressure, pulse wave velocity (PWV) and augmentation index, basal and during inhibition of nitric oxide synthesis in healthy subjects.
Tolvaptan is a vasopressin antagonist (V2-antagonist) and is used in treatment of
hyponatremia. Animal studies have demonstrated that inhibition of V2 receptors in the renal
principal cell increases renal free water clearance and renal sodium excretion.
Treatment with V2-receptor antagonists increases vasopressin concentration in plasma that
stimulates V1-receptors in the vascular bed. This may change both central and peripheral
hemodynamics and plasma concentration of vasoactive hormones. Changes in hemodynamics and
hormone concentration may consequently change renal sodium and water handling.
The nitric oxide system plays a central role in both renal sodium and water handling and
regulation of vascular tone and blood pressure.
The effects of tolvaptan the circulation and kidneys is investigated by using measurements
of biomarkers specific for the sodium/water balance in the urine and by measurements of
vasoactive hormones in the blood after administration of tolvaptan and L-NMMA infusion.
