Inclusion Criteria:

1. Mild-to-moderate hypertension defined as a baseline mean seated DBP of greater than or equal to 95 mm Hg and less than or equal to 109 mm Hg and a baseline 24-hour ABPM mean DBP of greater than or equal to 85 mm Hg.

Exclusion Criteria:

5. Hepatic and/or renal dysfunction as defined by the following laboratory parameters:

   • SGPT (ALT) or SGOT (AST) > 2 times the upper limit of normal range.
   • Serum creatinine > 2.3 mg/dL (or > 203 µmol/l).
6. Bilateral renal artery stenosis, renal artery stenosis in a solitary kidney, post-renal transplant patients or patients with only one kidney.
