Changes in blood pressure are to be compared between the losartan / HCTZ group and the losartan and amlodipine combination group in hypertensive patients with metabolic syndrome. Metabolism markers (HOMA-R and adiponectin), an oxydative stress markers (8OHdG), microalbuminuria and hs-CRP are also to be compared between two groups.
This study aims to demonstrate that antihypertensive effect is significantly better in the losartan / HCTZ group compared with the losartan and amlodipine combination group, while there is no significant difference in tolerability and effect on metabolism between two groups.

Phase IV
Change in systolic blood pressure after 12 weeks of treatment
- Change and % change in blood pressure after 12 and 24 weeks of treatment (excluding change in systolic blood pressure after 12 weeks of treatment)
- Change and % change in Adiponectin, 8OHdG, HOMA-R, microalbuminuria, hs-CRP after 12 and 24 weeks of treatment
- Safety throughout the treatment period
- For other laboratory test values, exploratory analysis is to be conducted to analyze variations within a group and/or between two groups.
