Comparison of Repaglinide and Metformin Combination Tablet Versus Repaglinide and Metformin as Separate Tablets in Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
This trial is conducted in Asia. The aim of this clinical trial is to investigate the bioequivalence of repaglinide and metformin combination tablet versus repaglinide and metformin as coadministered tablets after meal. The trial is designed as a three-period, six-sequence, single-dose, crossover pharmacokinetic trial where the trial participant is randomised to one of six possible treatment periods (Williams design). The trial participant will receive one single dose of each trial product in varying order.
