Effects of Inhibition of NO-Synthesis on Renal Hemodynamics and Sodium Excretion in Patients With Essential Hypertension and Healthy Controls

This study has been completed.

Sponsored by:	Holstebro Hospital
Information provided by:	Holstebro Hospital
ClinicalTrials.gov Identifier:	NCT00345150

Purpose

The study tests the hypothesis that systemic and renal nitric oxide synthesis is changed in essential hypertension by investigating the effects of a non selective nitric oxide inhibitor on renal hemodynamics and sodium excretion in patients with essential hypertension. The results are compared with a group of healthy subjects.
