Study Overview
=================
Brief Summary
-----------------
This study is a randomized, open-label, fasted, single dose, crossover study to evaluate the pharmacokinetic profiles and safety of CKD-374 5 mg in healthy volunteers.

Detailed Description
-----------------
To healthy subjects of thirty-six (36), following treatments are administered dosing in each period and wash-out period is a minimum of 7 days. Reference drug: D569 Tab. / Test drug: CKD-374 5mg Tab. Pharmacokinetic blood samples are collected up to 12hrs. The pharmacokinetic characteristics and safety are assessed
