The active study medication has been approved by the U.S. Food and Drug Administration for the treatment of high blood pressure and is available by prescription. Study investigators hope to gain information that could help prevent some of the complications of hypertension, such as blood vessel and heart damage. Study participants will be asked to attend four clinic visits and follow a special sodium-controlled diet for three days prior to the second and third clinic visits. Food will be provided. Blood samples and other physiological measurements such as breathing, pulse and blood pressure, will be taken during clinic visits.
Compensation is available.
