The subject should not chew or break the drug, but should swallow in whole with water. The difference in administration time between the subjects is about one minute apart, considering the blood collection time.

3. Wash out period: at least 7 days

4. Blood collection time: Before the administration,15, 30, 45 min, 1, 1.5, 2, 2.5, 3, 3.5, 4, 6, 8, 12, 24, 48 hours after the administration (total 16 times)

5. A person with a history of regular alcohol intake within a month prior to the first administration of the IP:

   • Male: More than 21 cups/week
   • Female: More than 14 cups/week (1 cup: 50 ml of soju, 250 ml of beer, 30ml of spirits)

6. A person who is hypersensitive to any of the IP components

7. A person who has medical history of mental disease
