Who has drug abuse history or positive result at urine screening tests (cannabinoid, opioid, amphetamine, cocaine, barbiturate, benzodiazepine) Who has smoked within 3 months before study drug administration (Smoker who has stopped smoking for more than 3 months before study drug administration is eligible to participate) Who has confirmed positive at serological tests (HBs antigen, HCV antibody and HIV antibody) Who consistently consumes alcohol Who has participated in other clinical study within 8 weeks before study drug administration (however, the last dosing day is considered as the end of clinical study.) Who has had bleeding or blood collection and donation over 400 mL within 8 weeks before study drug administration Who donated whole blood within 2 months before study drug administration, who donated via plasmapheresis/plateletpheresis within 1 month before study drug administration, or who received a blood transfusion within 1 month before study drug administration Whose vital sign measured at sitting position after resting at least 3 minutes is as following Low blood pressure (Systolic pressure: less than 90 mmHg, Diastolic pressure: less than 60 mmHg) High blood pressure (Systolic pressure: higher than 150 mmHg, Diastolic pressure: higher than 100 mmHg) Who is determined ineligible for study participation by investigators for any reason including clinical lab test and ECG results.
