Study Description

Brief Summary:

The purpose of the study was to assess efficacy and safety of fixed dose combination of 5 mg amlodipine/80 mg valsartan compared to 160 mg valsartan monotherapy in lowering blood pressure in Taiwanese patients.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Amlodipine 5mg/Valsartan 80 mg; During double-blind treatment period, patients randomized to combination therapy received daily one dosage (Amlodipine/Valsartan 5mg/80mg) with one single tablet size for 8 weeks.	Drug: Amlodipine 5mg/Valsartan 80 mg; Combination therapy of Amlodipine/Valsartan 5mg/80mg one dosage daily with one single tablet size for 8 weeks.; Other Name: Exforge
Active Comparator: Valsartan 160 mg; In double blinded treatment period, patients randomized to this arm received 160 mg Valsartan once daily for 8 weeks.	Drug: Valsartan; For run-in period, Valsartan 80 mg daily in one dosage with one single tablet size for 4 weeks. Monotherapy for double blind treatment period in one dosage (Valsartan 160mg) daily with one single tablet size for 8 weeks; Other Name: Diovan
Run-In Valsartan 80 mg; During run-in period, oral valsartan 80 mg once daily for 4 weeks.	Drug: Valsartan; For run-in period, Valsartan 80 mg daily in one dosage with one single tablet size for 4 weeks. Monotherapy for double blind treatment period in one dosage (Valsartan 160mg) daily with one single tablet size for 8 weeks; Other Name: Diovan

Outcome Measures

Primary Outcome Measures :

1. Change From Baseline in Mean Sitting Systolic Blood Pressure (msSBP) From Office Blood Pressure Measurement [ Time Frame: Baseline and 8 weeks ]
   Two arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in mean sitting systolic blood pressure (msSBP) was calculated comparing the Week 8 readings to the readings taken at baseline.
2. Change From Baseline in Mean Sitting Diastolic Blood Pressure (msDBP) From Office Blood Pressure Measurement [ Time Frame: Baseline and 8 weeks ]
   Two arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in mean sitting diastolic blood pressure (msDBP) was calculated comparing the Week 8 readings to the readings taken at Baseline.

Secondary Outcome Measures :

1. Change From Baseline in Mean Systolic Blood Pressure (mSBP) From Ambulatory Blood Pressure Measurement (ABPM) Over 24 Hours [ Time Frame: Baseline and 8 weeks ]
   Validated automated ambulatory blood pressure monitors were dispensed to participants with instructions on correct use. Automated blood pressure readings were obtained every 15-30 minutes during waking hours and every 30-60 minutes during sleep for a total of 24 hours. The change in mean systolic blood pressure (mSBP) over 24 hours was measured from baseline to 8 weeks of treatment during the double-blind phase.
2. Change From Baseline in Mean Diastolic Blood Pressure (mDBP) From Ambulatory Blood Pressure Measurement (ABPM) Over 24 Hours After 8 Weeks of Treatment During the Double-blind Phase [ Time Frame: Baseline and 8 weeks ]
   Validated automated ambulatory blood pressure monitors were dispensed to participants with instructions on correct use. Automated blood pressure readings were obtained every 15-30 minutes during waking hours and every 30-60 minutes during sleep for a total of 24 hours. The change in mean diastolic blood pressure (mDBP) over 24 hours was measured from baseline to 8 weeks of treatment during the double-blind.
3. Number of Participants With Adverse Events During Double-blind Phase [ Time Frame: 8 weeks ]
