Introduction: Conventional antidepressants, including fluoxetine, have a major disadvantage in delayed onset of efficacy. Yueju, an herbal medicine used to treat mood disorders was recently found to exhibit rapid antidepressant effects. The present study was conducted to evaluate the role of Yueju in rapidly acting on major depressive disorder (MDD).
Methods: Participants were MDD patients with scores of 24-item Hamilton Depression Rating Scale (HDRS-24) ≥20 and without history of antidepressant use. They randomly received daily oral doses of Yueju (23 g/day) plus fluoxetine (20 mg/day) (experimental group) or placebo plus fluoxetine (control group) for 7 days. HDRS-24 was used as the primary outcome measurement at baseline, and on days 1, 3, 5, and 7. Concentrations of serum brain-derived neurotrophic factor (BDNF) were assessed at baseline and on days 1 and 7.
Results: In all, 18 participants met the criteria for data analysis. Compared to baseline level, only experimental group showed significant decrease of HDRS-24 score from day 3 to day 7 (P<0.05). Experimental group also showed significant improvement compared with control group from day 3 to day 7 (P<0.05). No correlation between treatment outcomes with serum BDNF levels was observed. However, experimental group showed significant correlation for serum BDNF level on day 1 with day 7 (r=0.721, P=0.028), whereas the control group did not.
Conclusion: Yueju likely contributes to fast-onset antidepressant effects on MDD. Further investigation is necessary to firmly establish the ancient formula as a safe, efficacious, and rapidly acting alternative medicine for MDD treatment.
