Study Arms:
- Aliskiren + Amlodipine (Type: EXPERIMENTAL): Eligible participants received oral aliskiren 150 mg + amlodipine 5 mg daily from week 1-8. From week 8 - 16, the dose of the combination treatment increased to aliskiren 300 mg + amlodipine 10 mg daily. From week 16-24, participants in this group continued combination treatment (aliskiren 300 mg + amlodipine 10 mg) for 8 weeks. At week 24, if blood pressure was not adequately controlled (systolic blood pressure \>140 mmHg or diastolic blood pressure \>90 mmHg) hydrochlorothiazide 12.5 mg was added to the combination (aliskiren 300 mg + amlodipine 10 mg) for an additional 8 weeks. Total treatment period =32 weeks.
- Aliskiren Start - Amlodipine Add-On (Type: EXPERIMENTAL): Eligible participants received oral aliskiren 150 mg daily from week 1-8. From week 8 - 16, the dose of aliskiren increased to 300 mg daily. From week 16-24, amlodipine 10 mg was added to the aliskiren 300 mg for 8 weeks (aliskiren 300 mg + amlodipine 10 mg). At week 24, if blood pressure was not adequately controlled (systolic blood pressure \>140 mmHg or diastolic blood pressure \>90 mmHg) hydrochlorothiazide 12.5 mg was added to the combination (aliskiren 300 mg + amlodipine 10 mg) for an additional 8 weeks. Total treatment period =32 weeks.
- Amlodipine Start- Aliskiren Add-On (Type: EXPERIMENTAL): Eligible participants received oral amlodipine 5 mg daily from week 1-8. From week 8 - 16, the dose of amlodipine increased to 10 mg daily. From week 16-24, aliskiren 300 mg was added to the amlodipine 10 mg for 8 weeks (amlodipine 10 mg + aliskiren 300 mg). At week 24, if blood pressure was not adequately controlled (systolic blood pressure \>140 mmHg or diastolic blood pressure \>90 mmHg) hydrochlorothiazide 12.5 mg was added to the combination (amlodipine 10 mg + aliskiren 300 mg) for an additional 8 weeks. Total treatment period =32 weeks.
