Primary Outcome Measures:
  • Changes in Mean Sitting DBP From Baseline After 4 Weeks of Therapy [ Time Frame: 4 weeks ]
    Mean of the changed DBP from baseline after 4 weeks


Secondary Outcome Measures:
  • Changes in Mean Sitting SBP From Baseline After 4 Weeks of Therapy [ Time Frame: 4 weeks ]
    Mean of the changed SBP from baseline after 4 weeks

  • Proportion of Patients Achieving Goal of Mean Trough Sitting DBP (<90 mmHg, But <80 mmHg for DM & Chronic Kidney Disease) and SBP (<140 mmHg, But <130 mmHg for DM & Chronic Kidney Disease) After 4 Weeks of Therapy [ Time Frame: 4 weeks ]
    Percent of the patients achieving goal DBP and SBP after 4 weeks

  • Proportion of Patients Achieving Goal of Mean Trough Sitting DBP (<90 mmHg, But <80 mmHg for DM & Chronic Kidney Disease) and SBP (<140 mmHg, But <130 mmHg for DM & Chronic Kidney Disease) After 8 Weeks of Therapy [ Time Frame: 8 weeks ]
    Percent of patients achieving goal of DBP

  • Changes in Mean Sitting SBP From Baseline After 8 Weeks of Therapy [ Time Frame: 8 weeks ]
    Changed SBP from baseline after 8 weeks

  • Changes in Hs-CRP Level From Baseline After 8 Weeks of Therapy [ Time Frame: 8 weeks ]
    Change of hs-CRP from basline after 8 weeks

  • Occurrence of Adverse Events (AE) and Discontinuation of Study Medication Due to AE's From Baseline (Randomisation) to the End of the Study (8 Weeks) [ Time Frame: 8 weeks ]
    Occurred number of AE and disconinuation of study medication due to the AE from basline after 8 weeks

  • Compliance Levels at 4 Weeks and 8 Weeks of Therapy [ Time Frame: 8 weeks ]
    Percent of the number of returened pills to the number of prescrited pills
