24 subjects were entered in to the study and randomly assigned to treatment sequence according to randomization schedule before first administration of the Investigational Medicinal Product (IMP). One subject was withdrawn from the study after Treatment Period 1 (Reference Product) because they vomited within 2 times median Tmax. As a result, 24 subjects completed dosing of Reference Product and 23 subjects completed the study.
