This study is a randomized, open-label, single dose, 3-period partial replicated crossover study to evaluate the pharmacokinetic profiles and safety of CKD-333 low dose in healthy volunteers under fasting conditions.

To healthy subjects of fifty-one (51), following treatments are administered dosing in each period and wash-out period is a minimum of 14 days.

Reference drug: 1) Cantabell Tab. 8/5mg 2) Lipitor Tab. 10mg / Test drug: CKD-333 8/5/10mg Tab.

Pharmacokinetic blood samples are collected up to 72hrs. The pharmacokinetic characteristics and safety are assessed.
