Description

Inclusion Criteria:

  • Prehypertensive: Having systolic BP between 120 to 139 mmHg and/or diastolic BP between 80 to 89 mmHg during screening visit. BP will be measured manually tree times at 10 minutes interval after subjects sit quietly for at least 5 minutes in a chair. The average of last two BP measurements will be taken into consideration.
  • Male or female of Caucasian or African-American origin.
  • No history of any major past and current medical illness (such as diabetes, renal disease, liver disease etc.)
  • Not taking any medication that affects blood pressure.

Exclusion Criteria:

  • HbA1C > 7.0 % during screening visit.
  • Serum potassium > 5.5 mEq/L during screening and/or any testing visit due to risk of developing hyperkalemia.
  • Serum creatinine > 1.5 mg/100 ml and/or creatinine clearance < 50 ml/min* (Glomerular Filtration Rate Estimate by Abbreviated MDRD Study Equation)35 during screening and/or any testing visit due to risk of developing renal dysfunction.
  • Female having positive pregnancy test during screening and/or any testing visit.
