Paroxetine versus Vortioxetine for Depressive Symptoms in Postmenopausal Transition: A Preliminary Study.

Background: The impact of menopause is a consequence of social, physical and mental changes; hormonal changes play an important role in inducing an increased risk of developing depressive symptoms. It is essential to treat mood and vasomotor symptoms and to prevent their onset to promote an improvement in the quality of life, both in terms of clinical and psychological conditions.

Objective: This observational study aims to compare paroxetine and vortioxetine in a sample of patients affected by postmenopausal depression attending the Anxiety and Depression Clinic in terms of: efficacy in determining clinical remission (HDRS ≤ 7) and tolerability; improvement of autonomic and cognitive symptoms.

Methods: 39 female outpatients with a diagnosis of Postmenopausal Depression (according to DSM-5 criteria) were evaluated as the routine clinical practice through the following scales: Hamilton Depression Rating Scale (HDRS); Menopause Rating Scale (MRS); Montreal Cognitive Assessment (MoCA); Antidepressant Side-Effect Checklist (ASEC); data from/of baseline, after 8 weeks and 12 weeks were recorded.

Results: Both antidepressants resulted to be effective in clinical remission (HDRS ≤ 7) without statistical differences between the two groups (p = 0.3), although paroxetine showed a faster remission than vortioxetine (p = 0.01). Autonomic symptoms showed a higher improvement in the vortioxetine group (p = 0.002). Paroxetine group referred insomnia and sexual problems while patients taking vortioxetine referred diarrhoea and palpitations. Data show a superiority of cognitive performance in the Paroxetine group (p = 0.005), contrary to what stated in literature.

Conclusions: Data are related to a small sample retrospectively assessed trough a 6-month observation period. Thus, the preliminary results need further research to be confirmed.
