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.

Condition Intervention Phase
Essential Hypertension
Drug: Eprosartan
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double-Blind
Official Title: 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.
