Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will compare the antihypertensive efficacy and safety of a valsartan/amlodipine-based treatment with a losartan-based treatment in patients with Stage 2 systolic hypertension (high blood pressure, mean systolic blood pressure greater than 160 and less than 200 mmHg).

Valsartan/amlodipine/HCTZ

Valsartan/amlodipine-based regimen: at randomization (Visit 3) patients were treated with valsartan/amlodipine 160/5 mg for 3 weeks, followed by a forced titration at Visit 4 (Week 3) to valsartan/amlodipine/HCTZ 160/5/25 mg for 3 weeks, and a second forced titration at Visit 5 (Week 6) to valsartan/amlodipine/HCTZ 320/10/25 mg for the remaining 6 weeks of the study.

Group Type EXPERIMENTAL

valsartan, amlodipine, HCTZ

Intervention Type DRUG

combination Valsartan/amlodipine160/5 mg tablet for 3 weeks; Valsartan/amlodipine 160/5mg tablet +HCTZ 25 mg capsule for 3 weeks; valsartan/amlodipine 320/10 mg tablet + HCTZ 25mg capsule for remainder (6 weeks) of the study

Losartan/HCTZ

Losartan-based regimen: at randomization (Visit 3) patients were treated with losartan 100 mg for 3 weeks, followed by a forced titration at Visit 4 (Week 3) to losartan/HCTZ 100/25 mg. At Visit 5 (Week 6) patients were switched to valsartan/amlodipine/HCTZ 160/5/25 mg for 3 weeks and, at Visit 6 (Week 9), patients were force titrated to valsartan/amlodipine/HCTZ 320/10/25 mg for the final 3 weeks of the study.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Male or female outpatient of 18 years of age or greater
* Stage 2 systolic hypertension defined as office Mean Sitting Systolic blood pressure (MSSBP) greater than or equal to 160 and \< 200 mmHg at randomization
* Patients who were able to participate in the study, and who gave written informed consent before any study assessment was performed.

Exclusion Criteria

* Office systolic blood pressure \>200 and/or mean sitting diastolic blood pressure (MSDBP) greater than or equal to 110 mmHg at Visit 1.
* Use of four (4) or more antihypertensive medications within 30 days of Visit 1.
* Refractory hypertension, defined as blood pressure \>140/90 mmHg while taking three (3) drugs at the maximum dose of each drug, one of which must be a diuretic. (Therapy with a fixed-dose combination of two active medications represents two drugs).
* Inability to safely discontinue all antihypertensive medications for 1-2 weeks prior to randomization.
