No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The purpose of this study is to evaluate the effect of vortioxetine (10 and 20 mg, once daily) versus paroxetine (20 mg, once daily) on sexual functioning in healthy participants after 5 weeks of double-blind treatment.
