简要总结
The study is to compare the rate and extent of absorption of a generic formulation with that of a reference for mulation when given as equal labeled dose. The study will be randomized, open-label, single dose, two way crossover design with two-period, two-treatment and two-sequence under fasting condition and at least 28 days washout period between the doses.
详细描述
Title A Bioequivalence study of a randomized, open-label, single dose, two-way crossover design with two-period, two-treatment and two-sequence of Drospirenone (3 mg) + Ethinyl Estradiol (0.03 mg) Tablets relative to Yasmin® in healthy Thai female volunteers under fasting condition.
Objectives The primary objective is to compare the rate and extent of absorption of a generic formulation with that of a reference formulation when given as equal labeled dose. The secondary objective is to evaluate the safety after oral administration of both test and reference formulation in healthy Thai female volunteers.
Study Design Randomized, open-label, single dose, two-way crossover design with two-period, two-treatment and two-sequence under fasting condition and at least 28 days washout period between the doses.
Sample Size 32 Healthy Human Thai female subjects. Two extra subjects if available, may be checked-in on the day of check in of period-I to compensate for any dropout prior to dosing of period-I. These subjects will be dosed if there are dropouts prior to dosing in period-I. If there are no dropouts, these subjects will be checked-out without being dosed after completion of dosing in period-I.
