Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Female or male patient with age ≧ 18 years old.
  • Patient with mild to moderate uncomplicated essential hypertension, and the blood pressure not adequately controlled on existing antihypertensive treatment.
  • Patient with sitting systolic blood pressure (sSBP)/ sitting diastolic blood pressure (sDBP) ≦ 180/110 mmHg at screening visit.
  • For non-diabetic patient, sitting systolic blood pressure (sSBP) ≧ 140 mmHg or sitting diastolic blood pressure (sDBP) ≧ 90 mmHg at baseline visit; for diabetic patient, sitting systolic blood pressure (sSBP) ≧ 130 mmHg or sitting diastolic blood pressure (sDBP) ≧ 80 mmHg at baseline visit.
  • Patient or his/her legally acceptable representative has signed and dated the informed consent form.

You may not qualify if:

  • Known or suspected secondary hypertension.
  • sSBP \> 180 mmHg or sDBP \> 110 mmHg at baseline visit.
  • Patients taking more than two anti-hypertensive medications at the screening visit. (Fixed-dose combinations of two or more antihypertensive therapies will be counted as two or more antihypertensive medications.)
  • Known NYHA functional class Chronic Heart Failure (CHF) III and IV.
  • With a history of myocardial infarction, transient ischemic attack or cerebrovascular accident within the preceding 6 months, clinically significant valvular heart disease, or hepatic and/or renal dysfunction as defined by the following laboratory parameters
  • SGPT (ALT) or SGOT (AST) \> two times upper the limit of normal range
  • Serum creatinine \> 2.3 mg/dl or creatinine clearance \< 30 ml/min
