Clinical Trial to Assess the Pharmacokinetic Characteristics of Lodivixx Tab. 5/160mg in Healthy Male Subjects (N=27)

The purpose of this study is to assess the pharmacokinetic characteristics of valsartan and S-amlodipine after single oral administration of Exforge tab. 10/160mg, a combination formulation of valsartan and amlodipine as reference drug and Lodivixx tab. 5/160mg, a combination formulation of valsartan and S-amlodipine as test drug in healthy male adults. Additionally the safety and tolerability of two drugs will be evaluated.
