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.
