Outcome Measures

Primary Outcomes (1)

  • Compared to placebo, gabapentin effectiveness in reducing hot flash scores in postmenopausal women

Secondary Outcomes (3)

  • The toxicity profile of gabapentin in this population compared with placebo

  • The impact of gabapentin on quality of life in this population compared with placebo

  • Correlation of the Menopause-specific Quality of Life (MENQOL) results with the change in hot flash scores
