Clinical Study to Investigate the Pharmacokinetic Profiles and Safety of Highdose CKD-385 in Healthy Volunteers(Fasting)

Study Overview
=================
Brief Summary
-----------------
This study is a randomized, open-label, fasting, single dose, crossover study to investigate the pharmacokinetic profiles and safety of high-dose CKD-385 in healthy volunteers under fasting conditions.

Detailed Description
-----------------
To 16 healthy subjects, following treatments are administered dosing in each period and wash-out period is a minimum of 7 days. Reference drug: D744 Test drug: CKD-385 64 mg formulation I Pharmacokinetic blood samples are collected up to 48 hrs. The pharmacokinetic characteristics and safety are assessed.
