Conditions: Healthy

Summary: an open-label, randomized, 2-sequence, 2-period, fasted condition, single-dose, per oral, cross-over study to evaluate the bioequivalence of "dong-a bepotastine besilate tab" (bepotastine besilate 10mg) and "twolion tab" (bepotastine besilate 10mg) in healthy volunteers

1. study design: an open-label, randomized, 2-sequence, 2-period, fasted condition, single-dose, per oral, cross-over study 2. administration method: the subject should maintain a minimum of 10 hours of empty stomach before administration, and give an oral dose of 1 tablets (bepotastine besilate 10 mg) with 150 ml of water at around 8 a.m. on the day of the test at room temperature. the test subject should not chew the drug or break it, but should swallow in whole with water. the difference in administration time between the test subjects is about one minute apart, considering the collection time. 3. wash out period: 7 days 4. blood collection time: before the administration, 0.25, 0.5, 0.75, 1, 1.33, 1.67, 2, 3, 4, 6, 8, 12 hr after the administration (total 13 times) 5. analysis: measurement of the concentration of an unchangeable substance of bepotastine in plasma
