Brief Summary:
This will be a multi-center, prospective, randomized, open-label, parallel design, two arm comparator trial. In the proposed study, the investigators will compare low-dose combination therapy of Nifedipine GITS/OROS plus Valsartan with up-titrated monotherapy of Valsartan with respect to their blood pressure-decreasing effects in patients with essential hypertension.The study consists of a screening visit, followed by randomization and administration of either Nifedipine GITS/OROS 30 mg in combination with Valsartan 80 mg or Valsartan 160 mg for 12 weeks of treatment.The primary efficacy parameters will be mean SBP and DBP on office BP monitoring at 12 weeks of treatment compared to baseline.

Arm Intervention/treatment
Experimental: Arm 1 Drug: Adalat (Nifedipine, BAYA1040)
Nifedipine GITS/OROS 30 mg OM + Valsartan 80 mg OM

Active Comparator: Arm 2 Drug: Diovan (Valsartan)
Valsartan 160 mg OM (Two Valsartan 80mg tablets)

Primary Outcome Measures :
  1. Mean Systolic BP and Diastolic BP on office Blood Pressure monitoring [ Time Frame: Baseline and 12 weeks of treatment ]

Secondary Outcome Measures :
  1. Response rate (>/=10mmHg decrease of office SBP and >/=5mmHg decrease of office DBP) [ Time Frame: 8 and 12 weeks of treatment ]
  2. Control rate (</=140/90 of office BP) [ Time Frame: 8 and 12 weeks of treatment ]
  3. Change in pulse pressure (difference between SBP and DBP) [ Time Frame: 12 weeks of treatment ]
  4. Reduction in Urinary microalbumin excretion(UAE) in patients with microalbuminuria [ Time Frame: Baseline and 12 weeks of treatment ]
  5. Adverse Event reporting [ Time Frame: At the start, every 4 weeks during treatment and at the end of treatment ]
  6. Vitals signs [ Time Frame: At the start, every 4 weeks during treatment and at the end of treatment ]
  7. Laboratory tests [ Time Frame: At the start and at the end of treatment ]
