Primary Outcome Measures:
  • The primary endpoint is the mean blood pressure change systolic blood pressure/diastolic blood pressure(SBP/DBP) from baseline after 24±2 weeks of treatment or at the last observation in case of early withdrawal. [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The key secondary endpoints include the percentage of patients achieving target blood pressure SBP/DBP <140/90 mmHg. [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The key secondary endpoints include the percentage of patients achieving DBP response (defined as mean seated DBP < 90 mmHg or a drop of greater than or equal to 10 mmHg). [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The key secondary endpoints include the percentage of patients achieving SBP response (defined as mean seated SBP < 140 mmHg or a drop of greater than or equal to 10 mmHg). [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The key secondary endpoints include the change from baseline of quality of life assessment data measured by World Health Organization Quality of Life Assessment Instrument (WHOQOL-BREF) and EuroQol Visual Analogue Scale (EQ VAS). [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The other secondary endpoints include the mean blood lipid change (High Density Lipoprotein Cholesterol, Low Density Lipoprotein Cholesterol, Triglycerides, and Total Cholesterol). [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The other secondary endpoints include the percentage of patients achieving normal Body Mass Index (18.5 kg/m2 to 24.9 kg/m2). [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The other secondary endpoints include the percentage of patients who complied with each category of lifestyle modification recommendations. [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • The other secondary endpoints include the percentage of patient achieving SBP/DBP < 130/80 mmHg among patients with diabetes or kidney disease. [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
  • Safety will be evaluated by the incidence and severity of reported adverse events. [ Time Frame: 24±2 weeks ] [ Designated as safety issue: No ]
