Tibolone and Placebo in Adjunct to Antidepressant Medication for Women With Menopausal Depression

Longitudinal epidemiological studies have shown that many women experience significant physical and psychological changes as they approach menopause and for a long time following. Vasomotor symptoms (such as hot flushes, night sweats), sleep disturbances and changes in libido are common, and impact significantly on the quality of life, social and personal well-being. However, the major reason that many women seek help from menopause clinics or their doctors, is for depression and anxiety symptoms. As such, treatment commonly draws on traditional approaches for the management of major depression including the use of antidepressants such as selective serotonin reuptake inhibitors (SSRIs) or Selective Norepinephrine Reuptake Inhibitors (SNRIs) as the first line response. However, standard treatment of menopausal depression using antidepressants has only shown small improvements at best and at worst, is associated with severe side effects. Some SSRIs have been shown to be less effective in postmenopausal women compared to child bearing age women. Newer therapies directly targeting the disrupted hormonal systems (in particular estrogen) through the administration of such compounds as tibolone, have shown significant potential to treat depression with the added benefit of fewer adverse side effects. With growing evidence supporting the use of tibolone as a viable and improved treatment for menopausal depression, the investigators propose to investigate the potential of tibolone, a selective Hormone Replacement Therapy (HRT), to ameliorate de-novo or first onset depression occurring in the menopausal period.
