Eligibility Criteria
-----------------
Inclusion Criteria: A healthy male volunteer aged 20 to 55, and within 20% of ideal body weight. Have not any congenital or chronic diseases and medical symptom.

Exclusion Criteria: Take metabolic enzyme inducing or inhibiting drugs like barbiturates within 28 days prior to the first IP administration. show evidence of acute disease within 28 days prior to the first IP administration. Have the medical history of bleeding symptom or bleeding disease Have the disease history(ex. Inflammatory intestinal disease, stomach or duodenum ulcer, liver and bowels disease, appendectomy except of gastrointestinal surgery history) that may influence on the absorption, distribution, metabolism and excretion of the drug.
