The primary objective of this study is to investigate incremental cost effectiveness of Nifedipine CR and Amlodipine in combination therapy with Valsartan for the treatment of essential hypertensive patients.

To investigate incremental cost effectiveness, primary variables are mean treatment cost and achievement rate to target blood pressure level at the end of double-blind treatment period.

Condition Intervention Phase
Drug: Nifedipine (Adalat, BAYA1040)
Drug: Amlodipine (Norvasc)
Drug: Diovan
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Clinical Effect and Cost Effectiveness of Ca Antagonist in Combination With AII Receptor Antagonist in Patient With Essential Hypertension (PMS Study)

Primary Outcome Measures:
  • Mean treatment cost* for 16-week of double-blind treatment period [ Time Frame: 16 weeks ]
    * Including treatment cost for the drug related AEs. The sponsor will calculate the cost based on the tariff of health insurance scores.

  • Proportion of participants** achieving target blood pressure at the end of double-blind treatment period [ Time Frame: at week 16 ]
    **For subjects aged under 60 years: SBP<130mmHg and DBP<85mmHg, for subjects aged 60 years or over: SBP<140mmHg and DBP<90mmHg (SBP Systolic blood pressure, DBP Diastolic blood pressure)

Secondary Outcome Measures:
  • Treatment cost per subject to achieve the target blood pressure (Total costs for the double-blind treatment period / Number of patients who achieve the target blood pressure at the end of double-blind treatment period) [ Time Frame: 16 weeks ]
  • The change in blood pressure (SBP and DBP) from the baseline (end of pretreatment period) . [ Time Frame: baseline to week 16 ]
  • Proportion of participants for each age group to target blood pressure level [ Time Frame: at week 16 ]
  • Incidence of treatment-emergent drug-related adverse events [ Time Frame: 16 weeks ]
  • Safety variables will be summarized using descriptive statistics based on adverse events collections [ Time Frame: 16 weeks ]

Inclusion Criteria:

Untreated patients or patients with previous treatment by antihypertensive agents whose blood pressure at sitting position at the time of the entry (Visit 1) is:

  • SBP>/=160mmHg or DBP>/=100mmHg for untreated patients (SBP Systolic blood pressure, DBP Diastolic blood pressure)
