The aim of this trial is to determine the best dose combination of S-Amlodipine and
Telmisartan as compared to monotherapy by assessing the blood pressure lowering effects of a
once daily regimen of various combinations of S-Amlodipine and Telmisartan, compared to their
monotherapy components and placebo, in patients with stage I or II essential hypertension(a
mean seated cuff diastolic blood pressure >=95 and <=115 mmHg).
