Has a history of drug abuse or has a positive response to drug abuse on urine drug screening test. Has taken any prescription drugs or herbal medicine within 2 weeks prior to the expected date of first dose, or has taken or is expected to take any over-the-counter (OTC) drug, health functional food or vitamin preparation within 1 week prior to the expected date of the first dose (However, can participate in the study if otherwise eligible in the judgment of the investigator). Has participated in any other clinical study or bioequivalence study and received IPs within 6 months prior to the scheduled first dose. Has donated whole blood within 2 months prior to the scheduled first dose, or has donated blood components or received transfusion within a month prior to the scheduled first dose. Has a history of excessive smoking (> 10 cigarettes/day) within 3 months prior to the scheduled first dose or confirmed as positive for cotinine on urine drug screening test. Excessive caffeine intake (> 5 units/day), continued use of alcohol (> 21 units/week, 1 unit = 10 g of pure alcohol), or unable to stop drinking during hospitalization period. Unable to avoid caffeine-containing foods (e.g., coffee, tea [black tea, green tea, etc.], soda, coffee-flavored milk, and nutritive tonic drink) during the period from 24 hrs before hospitalization to discharge. Unable to use a medically acceptable contraceptive method throughout the study. ► Medically acceptable contraceptive methods include: Use of intrauterine device with a proven birth control failure rate by the spouse (or partner) Simultaneous use of (male or female) barrier method and spermicide Surgical sterilization of the subject or his partner (e.g., vasectomy, salpingectomy, tubal ligation, or hysterectomy) Determined ineligible for study participation by the investigator for other reasons such as clinical laboratory abnormalities.
