Clinical Trial to Assess the Pharmacokinetic Characteristics of Lodivikar Tab. 5/40 mg in Healthy Adult Male Subjects

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the pharmacokinetic characteristics of olmesartan and S-amlodipine after single oral administration of Sevikar tab. 10/40mg, a combination formulation of olmesartan and amlodipine as reference drug and Lodivikar tab. 5/40mg, a combination formulation of olmesartan and S-amlodipine as test drug in healthy male adults. Additionally the safety and tolerability of two drugs will be evaluated.
