Primary outcome: Change from baseline in mean sitting systolic blood pressure (msSBP) after 8 weeks treatment

Secondary outcome:

Change from baseline in mean sitting diastolic blood pressure (msDBP) after 8 weeks treatment

Change from baseline in Ambulatory Blood Pressure Measurement (ABPM) parameters after 8 weeks treatment

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- 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. Exclusion Criteria:

- 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.)
