July 20, 2017 updated by: Dong-Ju Choi, Seoul National University Bundang Hospital

Evaluation of the Efficacy and Safety of S-amlodipine+Chlorthalidone Combination Therapy and S-amlodipine+Telmisartan Combination Therapy in Hypertensive Patients Inadequately Controlled With Calcium Channel Blocker Monotherapy

Evaluation of the Efficacy and Safety of S-amlodipine+Chlorthalidone Combination Therapy and S-amlodipine+Telmisartan Combination Therapy in Hypertensive Patients Inadequately Controlled With CCB(Calcium Channel Blocker) Monotherapy

Study Overview

Detailed Description

The aim of this study is to verify the difference at week 12 from the baseline value in the average variation of diastolic blood pressure (sitDBP) of the study group in which S-amlodipine / Chlorthalidone combination therapy is to be used in patients with essential hypertension who did not adequately respond to monotherapy of amlodipine or S-amlodipine, compared to the control group, in which a combination therapy of S-amlodipine / telmisartan is to be used.
