Conditions

Treatment-resistant hypertension

Brief summary

Change in systolic blood pressure (sBP) from baseline on combined citrulline, folic acid, vericiguat and tadalafil treatment versus combined citrulline, folic acid and vericiguat as measured by 24-hour ABPM.

Detailed description

Changes in office sBP from baseline, incidence of achieving target office sBP (<140 mmHg), diastolic blood pressure (dBP) from baseline, in office dBP from baseline, number of circulatory mature endothelial cells (CEC), as well as change in albumin/creatinine ratio in morning spot urine will be explored.

Interventions

DRUGTadalafil Krka 5 mg filmdragerade tabletter
DRUGFolsyra Evolan 5 mg tablett
