Eligibility, for entry into active treatment period (Visit 3, Week -2): 170/90-115 mmHg

-History of cerebrovascular accident (stroke) or history of transient ischemic attacks within 1 year.
-Documented history of myocardial infarction or angina pectoris within 6 months.
-Clinically significant AV conduction disturbance, i.e., second- or third-degree AV block, or left bundle branch block. Sick-sinus syndrome or clinically significant bradycardia (resting heart rate <45 beats/minute).
-History of unexplained syncope within the prior 2 years, or a known syncopal disorder.
-Atrial flutter or atrial fibrillation or an accessory bypass tract (e.g., Stokes-Adams syndrome or Wolff-Parkinson-White syndrome).
-History of congestive heart failure or a known left ventricular ejection fraction <40%.
-Presence of hemodynamically significant obstructive valvular disease or cardiomyopathy.
-Percutaneous coronary angioplasty or coronary artery bypass surgery within the prior 6 months.

-Except as explicitly stated in the protocol, concomitant use of an agent that could cause a lowering of blood pressure is not permitted during the study (e.g., B-blockers [excluding ophthalmic preparations], diuretics, angiotensin-converting enzyme inhibitors, nitrates, calcium channel blockers).
-Patients taking major psychotropic agents such as phenothiazines, or chronic doses of antidepressants (used to treat depression) are not allowed. Lithium is not allowed.
-Regular use of NSAIDs or high-dose aspirin is not permitted, however, aspirin taken prophylactically as a cardioprotective agent al 100 mg/day is permitted. Acetaminophen is the preferred agent for pain relief.
-Concomitant use of oral steroids or ACTH is not allowed. Replacement hormones (thyroid, testosterone, estrogen) are permitted. Oral contraceptives are allowed unless the patient´s hypertension was induced by this medication.
-Serum Creatinine: females > 1.3 mg/dL (115umol/L); males > 1.4 mg/dL (124umoI/L)
-Proteinuiia>1+
-AST (SGOT), ALT (SGPT) >50% above normal values
-Clinically significant laboratory values outside of the established normal range including but not limited to any of the following parameters: hematocrit, hemoglobin or platelet count.
-White Blood Cell count <3000/mm^.
-Serum potassium <3.5 or >5.5mmol/L
-Hematuria of unknown etiology. Prior to patient entry, any hematuria should be evaluated, the etiology established/documented and treatment rendered as appropriate.
-In addition, patients will be excluded if they were known to be HIV or Hepatitis B positive although no screening is required.
-Patients will be excluded if they have a history of clinically important malabsorption or gastrointestinal resection or have cirrhosis of the liver.
