Effect of desvenlafaxine on mood and climacteric symptoms in menopausal women with moderate to severe vasomotor symptoms.

OBJECTIVE: To assess effects of desvenlafaxine (administered as desvenlafaxine succinate) on secondary outcomes of mood, climacteric symptoms, and treatment satisfaction in postmenopausal women with moderate to severe menopausal vasomotor symptoms (VMS).

METHODS: A 12-week, multicenter, double-blind, placebo-controlled trial was conducted in postmenopausal women with ≥ 50 moderate to severe hot flushes per week. Participants were randomly assigned to desvenlafaxine 100 mg/day, desvenlafaxine 150 mg/day, or placebo. Secondary outcome efficacy variables included Profile of Mood States (POMS), Greene Climacteric Scale (GCS), and Menopausal Symptoms Treatment Satisfaction Questionnaire (MS-TSQ) scores. Change from baseline in POMS total mood disturbance (TMD) score and subdomain scores were evaluated using analysis of covariance, adjusting for treatment and study site as factors and baseline score. GCS total and subdomain scores were analyzed similarly. Treatment satisfaction was analyzed using the row mean score test.

RESULTS: A total of 458 women were enrolled. At week 12, desvenlafaxine 100 mg/day significantly improved POMS TMD scores (p <0.001) and four of six POMS subdomains compared with placebo (all p ≤ 0.005). Women taking desvenlafaxine 100 mg/day experienced significantly greater improvement in GCS total scores (p <0.001) and five of six subdomains (all p ≤ 0.029) compared with placebo. Treatment with desvenlafaxine 100 mg/day resulted in significantly greater treatment satisfaction overall and in six of seven additional MS-TSQ items (all p ≤0.042). Desvenlafaxine 150-mg/day results were similar.

CONCLUSIONS: Desvenlafaxine treatment improved mood and climacteric symptoms in postmenopausal women with moderate to severe VMS compared with placebo, and more women were satisfied with desvenlafaxine treatment than with placebo.
