About
This study is designed to assess the safety and efficacy of twice-daily oral dosing of 6R-BH4 to improve endothelial function, reduce systolic blood pressure and reduce arterial stiffness.
Full description
By comparing values measured at different timepoints, the study is expected to provide insight regarding the ability of 6R-BH4, administered along with their currently prescribed antihypertension medications, to improve endothelial function, reduce SBP, and reduce arterial stiffness in patients with ISH and endothelial dysfunction
