Study Overview
=================
Brief Summary
-----------------
s-amlodipine besylate 2,5 mg tablet will be administered to patients have not received any hypertension treatment before or have received any of anti-hypertensive mono-therapy for the first four weeks of treatment. By increasing dose, s-amlodipine besylate 5 mg tablet will be administered for the last four weeks (4-8 weeks).
