Clinical Trial Summary

Treatment with nitrate has shown to lower blood pressure in both healthy subjects and hypertensive patients.Beside this nitrate have also shown to decrease arterial stiffness and improve endothelial function.But the effect of nitrate on renal blood flow, kidney function, water and salt balance and vasoactive hormones is still unclear. Therefore, the purpose of this study is to investigate the effect of orally administered nitrate on these parameters. This will be done in a double-blinded, placebo-controlled, crossover study. 20 healthy subjects will be treated, in a randomized order, with both potassium nitrate and placebo separated by at least 4 weeks wash-out.


Clinical Trial Description

Inorganic nitrate reduces blood pressure and improves endothelial function in both healthy subjects and hypertensive patients. This effect is thought to be caused through bioconversion to nitric oxide. Thus improving risk factors of cardiovascular decease by increasing vasodilatation, salt regulation and vasoactive hormones.The purpose of this study is to investigate the effect of inorganic nitrate on kidney function, hormones and circulation, which is still unknown. The effect of 4 days treatment with 24 mmol potassium nitrate capsules on heart rate, blood pressure, vasoactive hormones and urinary excretion of sodium and water will be measured in a randomized, placebo controlled, double blinded, crossover study in 20 healthy subjects. Each subject attends 2x2 examination days at least 4 weeks apart. The examination days are divided into 8 clearance periods of 30 min. each. The first 3 are baseline periods and in period 4 1 Liter of saline is administered to detect any difference in renal parameters after NaCl load. If inorganic nitrate supplementation is found to lower blood pressure in addition to favorable renal effects, it could lead to changes in the general treatment of high blood pressure and cardiovascular disease. ;
