Brief summary

This study is to assess the safety and efficacy of an add-on treatment algorithm with olmesartan, hydrochlorothiazide and amlodipine in patients with mild to moderate hypertension.

Interventions

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.

Participants by arm

ArmCount
Olmesartan+Hydrochlorothiazide,if Needed+Amlodipine, if Needed
Olemesartan 20 mg to start. Hydrochlorothiazide 12.5 mg and then 25 mg was added, if necessary. If blood pressure goal was still not achieved, amlodipine 5 mg and then 10 mg were added, if needed. Thus, the maximum combination was olmesartan 20mg + hydrochlorothiazide 25mg + amlodipine 10mg.

Outcome results

Primary

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.

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.

Time frame: Baseline to ≤20 weeks

Population: 691 = the full analysis set (FAS). FAS consists of all participants who received trial medication and who had data from at least one post-baseline visit with regard to the primary efficacy parameter, i.e., both the systolic and the diastolic blood pressure (BP) had to be measured. N is reduced for each treatment as subjects attain BP goals.
