Bioequivalence Study of Vortioxetine in 20 mg Coated Tablets in Healthy Subjects Under Fasting Conditions (ACL24-PC031)

Clinical Study to Determine Bioequivalence Between Two Oral Medications of Vortioxetine in 20 mg Coated Tablets in Healthy Subjects Under Fasting Conditions

Prospective, longitudinal, single-dose, randomized, open-label, crossover 2x2, two treatments, two periods, two sequences controlled clinical study

Study Overview

• Status: Completed
• Conditions: Bioequivalance
