E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose is to investigate if nebivolol is involded in regulation of systemic and renal nitric oxide system |
Formålet er at klarlægge om nebivolol er involveret produktion / regulation af kroppens NO-system. |
|
E.2.2 | Secondary objectives of the trial |
The objective is to measure the effect of nebivolol on L-NMMA induced changes in the renal tubular transport of sodium and water (FENa, u-ENaCβ, u-ENaCγ, CH2O, u-AQP2), hemodynamics (SBP, DBP, hjertefrekvens, central BP, AI) and plasma concentrations of vasoactive homones (renin, aldosterone, atrial natriuretic peptide, brain natriuretic peptide, vasopressin, endothelin) in patients withessential hypertension. |
Formålet er at måle effekten af nebivolol på L-NMMA inducerede ændringer i den renale tubulære transport af natrium og vand (FENa, u-ENaCβ, u-ENaCγ, CH2O, u-AQP2), central hæmodynamik (SBP, DBP, hjertefrekvens, central BP, AI) og vasoaktive hormoner (PRC, p-ang-II, p-Aldo, p-ANP, p-BNP, p-AVP, p-Endot) hos patienter med essentiel hypertension. |
