Bioequivalence Test of Dong-a Bepotastine Besilate Tab and Twolion Tab

Study Overview
=================
Brief 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

Detailed Description
-----------------
Study design: An open-Label, randomized, 2-sequence, 2-period, fasted condition, single-dose, per oral, cross-over study 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. Wash out period: 7 days 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) Analysis: Measurement of the concentration of an unchangeable substance of Bepotastine in plasma
