The antihypertensive effect of Amlodipine/Valsartan combination has been evaluated in worldwide populations including Asian patients. The study primarily aims to evaluate the effectiveness of Amlodipine/Valsartan combination in patients with essential hypertension in Taiwan using a prospective, open-label, non-randomized approach.

The study also wants to investigate the safety of Amlodipine/Valsartan combination during the 6-week treatment period.
