Diflucan Bioequivalence Study For Transferring The Manufacture

Overview

This study is to assess the bioequivalence between fluconazole 50mg capsules from two different manufacturers. This is a open-label, randomized, single dose, 2-treatment, 2-period crossover study in healthy Korean male and female subjects aged 19-55, to assess the bioequivalence after taking study drugs.
