Exclusion criteria

* 1\) Subject who have taken a drug that induces or inhibits drug metabolizing enzymes (e.g. barbiturates) within 1 month before the start of the study(date of first administration), or if taken a drug that may affect this study within 10 days before the start of the study(date of first administration). * 2\) Participated in another clinical trial or bioequivalence study and received an investigational product within 6 months of first dose of investigational product. * 3\) Donated whole blood within 8 weeks, blood components within 2 weeks, or received a transfusion within 4 weeks of first dose of investigational product. * 4\) Subject with a history of gastrointestinal resection that may affect drug absorption (excluding appendectomy and hernia surgery). * 5\) Subjects who meet any of the following criteria within 1 month prior to the first dose * a.
