Summary

In this study, we will assess the change of serum ACE-2, angiotensin(1-7), and vascular function after using olmesartan (an ARB), compared to conventional anti-hypertensive drug, amlodipine in hypertensive patients with T2DM.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Seoul National University Bundang Hospital
