Treatment and study plan

olmesartan medoxomil (OM)+ hydrochlorothiazide (HCTZ) tablets

Drug

olmesartan medoxomil (OM)+ hydrochlorothiazide (HCTZ)tablets 40mg/25mg + 20mg/25mg matching placebo tablets once daily for 8 weeks

olmesartan medoxomil (OM)/ hydrochlorothiazide (HCTZ) 20mg/25mg

Drug

olmesartan medoxomil (OM)/hydrochlorothiazide (HCTZ)20mg/25mg tablet + 40mg/25mg matching placebo tablet once a day for 8 weeks

Primary outcomes

  1. Change in Mean Trough Sitting Diastolic Blood Pressure

    Time frame: 8 weeks

    Change in mean trough sitting diastolic Blood Pressure between OM/HCTZ 20/25 mg vs. 40/25 mg, in those patients inadequately controlled on OM 40 mg monotherapy, after eight weeks of double blind treatment, as compared to baseline.

    Change = Week 16 - Week 8 (baseline).

Secondary outcomes

  1. Change in Mean Trough Sitting Diastolic Blood Pressure From Week 8(Baseline) to Week 12

    Time frame: 4 weeks

    Change = Week 12 - Week 8 (baseline).

  2. Change in Sitting Systolic Blood Pressure 4 Weeks and 8 Weeks After Baseline.

    Time frame: 8 weeks

    4 weeks Change = Week 12 - Week 8 (baseline). 8 weeks Change = Week 16 - Week 8 (baseline).

  3. Change in Daytime, Nighttime and 24-hour Blood Pressure Evaluated by Ambulatory Blood Pressure Monitoring 8 Weeks After Baseline.

    Time frame: 8 weeks

    Change = Week 16 - Week 8 (baseline).

  4. Number of Participants Achieving Blood Pressure Goal.

    Time frame: 8 weeks
