This study is an open-label, randomized, single dose, crossover study to evaluate the pharmacokinetics, safety and tolerability of CKD-388 in healthy subjects

To healthy 60 subjects, following treatments are administered dosing in each period and wash-out period is a minimum of 14 days.

Reference drug: D418 Tab. / Test drug: CKD-388 Tab. Pharmacokinetic blood samples are collected up to 72hrs. The pharmacokinetic characteristics and safety are assessed.
