Amlodipine / hydrochlorothiazide

Patients received an amlodipine 5 mg capsule plus a hydrochlorothiazide 12.5 mg capsule for 4 weeks and then were force titrated up to amlodipine 10 mg plus hydrochlorothiazide 25 mg for the remaining 4 weeks of the study. During the 8 weeks, patients also received 2 placebo tablets. Patients took a total of 4 pills each day orally with water in the morning at approximately 8:00 am, except on the morning of a study visit when they took their study medications after all visit procedures and assessments had been completed.

Aliskiren / amlodipine / hydrochlorothiazide

Patients received an aliskiren 150 mg tablet, a HCTZ 12.5 mg capsule and a placebo capsule for the first 3 days of treatment. Amlodipine 5 mg was then added for the remainder of the first 4 weeks of treatment. At the end of 4 weeks, patients were force titrated up to aliskiren / amlodipine / hydrochlorothiazide 300/10/25 mg for the remaining 4 weeks of the study. During the 8 weeks, patients also received a placebo tablet. Patients took a total of 4 pills each day orally with water in the morning at approximately 8:00 am, except on the morning of a study visit when they took their study medications after all visit procedures and assessments had been completed.
