Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Amlodipine + Valsartan
Participants received 160 mg Valsartan and 5 mg amlodipine orally once a day for 52 weeks.
If blood pressure was not normalized at week 4, treatment was uptitrated to valsartan/amlodipine 160/10 mg.
Participants with still uncontrolled hypertension could receive add-on antihypertensive medication.
|
160 mg film coated tablets taken orally once daily in the morning.
5 mg or 10 mg tablets taken orally once daily in the morning.
|
Active Comparator: Losartan + Hydrochlorothiazide
Participants received 100 mg losartan and 12.5 mg Hydrochlorothiazide (HCT) orally once a day for 52 weeks.
If blood pressure was not normalized at week 4, treatment was uptitrated to losartan/HCT 100/25 mg, respectively, until end of study.
Participants with still uncontrolled hypertension could receive add-on antihypertensive medication.
|
12.5 mg or 25 mg tablets taken orally once daily in the morning.
100 mg tablets taken orally once daily in the morning.

Percentage of Participants Who Experienced Adverse Events (AEs)
Time Frame: Baseline to week 52
|
An adverse event was the appearance or worsening of any undesirable sign, symptom, or medical condition occurring after obtaining informed consent even if the event was not considered to be related to study drug.
Medical conditions/diseases present before obtaining informed consent were only considered adverse events if they worsened after study start.
Abnormal laboratory values or test results constituted adverse events only if they induced clinical signs or symptoms, required study drug discontinuation or required therapy.
