Bioequivalence Study of Bilastine Tablets in Healthy Chinese Subjects

Bioequivalence Trial of Bilastine Tablets in Healthy Subjects in a Single-Center, Open, Randomized, Single-Dose, Double-Cycle, Double-Crossover Fasting State

Using a single-center, open, randomized, single-dose, double-cycle, double-crossover trial design method (washout period of 7 days), 40 screened and qualified healthy subjects were randomly divided into 2 groups, the T-R group and the R-T group, with 20 subjects in each group. The enrolled subjects entered the Phase I clinical research center 1 day prior to the first cycle of dosing, and fasted for 10 h or more prior to dosing. On the morning of the day of administration, 1 tablet of Bilastine (20 mg) developed by Shandong Hubble Kisen Biological Technology Co., Ltd. or 1 tablet of Bilastine (20 mg) licensed by Menarini International Operations Luxembourg S.A. were administered orally on an empty stomach.
