A Bioequivalence Study of Two Formulations of 10-mg Empagliflozin Tablets in Healthy Thai Volunteers Under Fasting Conditions

A Bioequivalence Study of Two Formulations of 10-mg Empagliflozin Tablets in Healthy Thai Volunteers Under Fasting Conditions

Objectives:

Primary:

to evaluate the bioequivalence of two formulations of Empagliflozin tablets, test formulation and reference innovator formulation, after a single oral dose administration in healthy Thai subjects under fasting conditions

Secondary:

To examine the pharmacokinetics and safety of test and reference formulations

Study Design:

A Bioequivalence Study of Two Formulations of 10-mg Empagliflozin Tablets in Healthy Thai Volunteers under Fasting Conditions

Subjects will be fasted at least 10 hours before dosing. After that a single dose of 10-mg Empagliflozin tablets will be administered along with 240 mL of drinking water under fasting condition. In each period, a total of 21 blood samples (approximately 6 mL each) from 21 sampling time points will be collected at pre-dose (6-mL tubes) and at 0.33, 0.67, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50, 4.00, 4.50, 5.00, 6.00, 7.00, 8.00, 10.00, 12.00, 14.00, 24.00, 36.00 and 48.00 h post dose. Blood glucose level will be measured at approximately pre-dose, 0.33, 0.67, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50, 4.00 hours post-dose in each period for subject's safety. During blood sample collection, one drop of blood will be used for this test.
