Vortioxetine for Menopausal Depression

Vortioxetine for Menopausal Depression and Associated Symptoms

The broad goal of this study was to examine the efficacy and tolerability of vortioxetine (flexible dose) for the treatment of major depressive disorder (MDD) in symptomatic women around the menopausal transition. We hypothesized that an eight-week treatment with vortioxetine would promote a significant improvement of depression symptoms and other menopause-related physical symptoms.

Forty-seven peri- and postmenopausal women were enrolled in this open-label study. This was an 8-week intervention using open-label vortioxetine with flexible dose between 5-20 mg, dependent on participant response and tolerability. In addition to assessment of depressive symptoms, improvement of menopause-related physical and emotional symptoms that occur with MDD, including vasomotor symptoms, cognition, fatigue, anxiety, sleep complaints, and quality of life, were also examined.

Inclusion Criteria:

1. Women aged 40-62 years who are perimenopausal or early postmenopausal (within 5 years of the last menstrual period if not surgically postmenopausal), including:

   1. Perimenopausal women who have experienced changes in menstrual cycle frequency or duration, and/or physical symptoms indicative of menopausal transition, as determined by clinician
   2. Women who are using the Mirena Intrauterine Device (IUD), with Follicle-stimulating hormone (FSH) level > 20 milli-International unit/ml (mIU/mL)

2. Women meeting Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) criteria for major depression (assessed by the Mini International Neuropsychiatric Interview - M.I.N.I.)

3. MADRS scores of at least 20 at baseline visit

4. Women with significant menopause-related physical symptoms, indicated by any of the following criteria:

   1. Greene Climacteric Scale total scores > 20;
