The Effect of Eprosartan on Hormones and Kidney Function in Patients With Essential Hypertension

May 5, 2008 updated by: Regional Hospital Holstebro

The Effect of Eprosartan in Patients With Essential Hypertension on Renal Tubular Function and Vasoactive Hormones During Baseline Conditions and After Activation of the Sympathetic Nervous System.

We, the investigators at Holstebro Hospital, want to test the hypothesis that eprosartan reduces the activity of the sympathetic nervous system in patients with essential hypertension - during baseline conditions and after activation of the sympathetic nervous system.
