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.

Condition Intervention Phase
Drug: Ng-monomethyl-L-arginine (drug)
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single Blind
Official Title: Phase 1 Study of the Effects of Systemic Nitric Oxide Inhibition With Ng-Monomethyl-L-Arginine on Renal Hemodynamics and Sodium Excretion in Patients With Essential Hypertension and Healthy Controls

Estimated Enrollment: 30
Detailed Description:

The study investigates the effects of Ng-monomethyl-L-arginine (L-NMMA) on:

  1. renal hemodynamics (renal plasma flow and glomerular filtration rate)
  2. renal sodium excretion
  3. lithium clearance and fractional lithium excretion
  4. plasma levels of vasoactive hormones
  5. blood pressure and heart rate
