Brief Summary:
The purpose of this study is to evaluate the blood pressure lowering effects of an amlodipine/losartan combination treatment and losartan/Hydrochlorothiazide combination treatment in patients with essential hypertension uncontrolled with losartan 100mg monotherapy.

Condition or disease Intervention/treatment Phase
Hypertension Drug: Amosartan® tab Drug: Cozaar® plus pro tab Phase 4

Detailed Description:
  • Quality assurance plan was implemented by site monitoring, including data validation and registry procedures and Source data verification to assess the accuracy, completeness by comparing the data to external data sources (medical records and paper case report forms).
  • Data dictionary contains the registry, including the source of the variable, coding information (MedDRA ver12.0), and normal ranges.
  • Statistical analysis were performed using SAS® Version 9.2, SAS institute, Cary, NC, USA

Primary Outcome Measures :
  1. Change from baseline in Mean Sitting Diastolic Blood Pressure (MSDBP) [ Time Frame: Baseline, Week 8 ]

Secondary Outcome Measures :
  1. Change from baseline in MSDBP [ Time Frame: Baseline, week 4 ]
