The aim of this research was to analyze gabapentin's effect on Pittsburgh Sleep Quality Index (PSQI) scores in menopausal women.


Secondary analysis of data from a cohort of menopausal women participating in a randomized, double-blind, placebo-controlled trial of gabapentin 300 mg three times daily (TID) for hot flashes. The outcomes of interest were PSQI global and factor scores at weeks 4 and 12.


Subjects randomized to gabapentin demonstrated improvement in the sleep quality factor score, compared to placebo-treated subjects, at 4 and 12 weeks (p < 0.03). There was also gabapentin-associated improvement in the global PSQI score (p = 0.004) and the sleep efficiency factor score (p = 0.05) at 4 weeks. There was no significant effect of gabapentin on the daily disturbance factor score.


Gabapentin may improve sleep quality in menopausal women with hot flashes. These results warrant further prospective investigation, with an emphasis on measuring subjective sleep quality and maintenance.
