Efficacy and Tolerability of Combination Antihypertensive Drug in Non-Responders to ARB monoTHerapy Using 24h ABPM

Study Summary

A majority of Korean doctors tend to add other antihypertensive rather than to titrate the same drug. However, we try to induce doctors to titrate the Sevikar than to add other antihypertensive if patients are not controlled with Sevikar 5/20mg(amlodipine 5mg + omlesartan 20mg). As above, for patients who are not controlled with Sevikar 5/20mg, doctors will proceed to other prescription pattern with other choices of titration to Sevikar 5/40, 10/40mg. It is important to evaluate BP lowering efficacy of Sevikar through the titration step in patients uncontrolled with Sevikar low dose. Thus, this study is designed to demonstrate the efficacy of Sevikar by titration in patients who are not controlled their BP with low dose of Sevikar.
