Brief Summary:
To determine whether the combination of nifedipine GITS and valsartan is more effective in reducing central blood pressure than nifedipine GITS or valsartan alone, and to determine whether nifedipine GITS is comparable to valsartan

Condition or disease Intervention/treatment Phase
Hypertension Drug: Nifedipine (Adalat, BAYA1040) and Valsartan Drug: Nifedipine (Adalat, BAYA1040) Drug: Valsartan Phase 4

Arm Intervention/treatment
Experimental: Arm 1 Drug: Nifedipine (Adalat, BAYA1040) and Valsartan
Combination treatment with nifedipine GITS 30mg and valsartan 80mg, Once daily

Active Comparator: Arm 2 Drug: Nifedipine (Adalat, BAYA1040)
Nifedipine 60mg, Once daily

Active Comparator: Arm 3 Drug: Valsartan
Valsartan 160mg, Once daily

Primary Outcome Measures :
  1. Central systolic blood pressure [ Time Frame: Week 8 ]

Secondary Outcome Measures :
  1. Change in central diastolic blood pressure and pulse pressure [ Time Frame: Week 4,8 ]
  2. Change in central systolic blood pressure [ Time Frame: Week 4 ]
  3. Change in brachial systolic blood pressure and diastolic blood pressure [ Time Frame: Week 4,8 ]
  4. Change in brachial pulse pressure [ Time Frame: Week4,8 ]
  5. Change in augmentation index and augmentation pressure [ Time Frame: Week 4,8 ]
  6. Response rate(≥10 mmHg decrease of brachial SBP and ≥5mmHg decrease of brachial DBP) [ Time Frame: Week 4,8 ]
  7. Control rate (≤140/90 mmHg, 130/80 mmHg for diabetes, of brachial BP [ Time Frame: Week 4,8 ]
