Primary Outcome Measures:
  • The Percentage of Participants Treated to Target Blood Pressure Goals Overall and for Each Treatment Step From Baseline to Completion of Treatment During Which the Goal Was Achieved. [ Time Frame: Baseline to ≤20 weeks ] [ Designated as safety issue: No ]
    For non-diabetic participants the target seated blood pressure goals were: Systolic - ≤130 mm Hg; Diastolic - ≤85 mm Hg. For diabetic participants the target seated blood pressure goals were: Systolic - <130 mm Hg; Diastolic - <80 mm Hg.


Secondary Outcome Measures:
  • Percentage of Participants Who Achieved Normalized Blood Pressure Overall and for Each Treatment From Baseline to Completion of the Treatment During Which Blood Pressure Goals Were Achieved [ Time Frame: Baseline to ≤20 weeks ] [ Designated as safety issue: No ]
    Normalized blood pressure is defined as a mean sitting systolic blood (sBP) pressure at trough of <140 mmHg and mean sitting diastolic blood pressure (dBP)of <90 mmHg for non-diabetic patients or a mean sitting sBP at trough of <130 mmHg and mean sitting dBP <80 mmHg for diabetic patients.

  • Percentage of Participants Who Were Diastolic Responders Overall and for Each Treatment From Baseline to the Completion of Treatment During Which Blood Pressure Goals Were Achieved. [ Time Frame: Baseline to ≤20 weeks ] [ Designated as safety issue: No ]
    Diastolic responders were defined as a participant who is a normaliser or has a lowering of the mean sitting diastolic blood pressure of ≥10 mmHg at trough.

  • Percentage of Participants Who Were Systolic Responders Overall and for Each Treatment From Baseline to the Completion of the Treatment During Which Blood Pressure Goals Were Achieved [ Time Frame: Baseline to ≤20 weeks ] [ Designated as safety issue: No ]
    Systolic responders defined as a participant who is a normaliser or has a lowering of the mean sitting systolic blood pressure of ≥20 mmHg at trough

  • Mean Change in Diastolic Blood Pressure Overall and for Each Treatment From Baseline to the Completion of the Treatment [ Time Frame: Baseline to ≤20 weeks ] [ Designated as safety issue: No ]
  • Mean Change in Systolic Blood Pressure Overall and for Each Treatment From Baseline to the Completion of the Treatment [ Time Frame: Baseline to ≤20 weeks ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1

Olmesartan medoxomil oral tablets for 4 weeks followed by, if necessary:

Olmesartan medoxomil oral tablets + hydrochlorothiazide oral tablets for 8 weeks, followed by, if necessary:

Olmesartan medoxomil oral tablets + hydrochlorothiazide oral tablets + amlodipine oral tablets for 8 weeks

 Drug: olmesartan medoxomil + hydrochlorothiazide, if necessary + amlodipine, if necessary
Olmesartan medoxomil oral tablets 20 mg for 4 weeks followed by, if necessary: Olmesartan medoxomil oral tablets 20 mg + hydrochlorothiazide oral tablets 12.5 mg for 4 weeks, followed by, if necessary: Olmesartan medoxomil oral tablets 20 mg + hydrochlorothiazide oral tablets 25 mg for 4 weeks, followed by, if necessary: Olmesartan medoxomil oral tablets 20 mg + hydrochlorothiazide oral tablets 25 mg + amlodipine oral tablets 5 mg for 4 weeks, followed by, if necessary: Olmesartan medoxomil oral tablets 20 mg + hydrochlorothiazide oral tablets 25 mg + amlodipine oral tablets 10 mg for 4 weeks. All study medications are to be taken once daily. The subject's participation completes when blood pressure goals are achieved.

Criteria

Inclusion Criteria:

  • Male and female patients age greater than or equal to 18 years with mild to moderate hypertension.
