Hot Flashes Clinical Trial
Official title:
A Randomized Trial of Gabapentin, Estrogen and Placebo for the Treatment of Postmenopausal Hot Flashes
To compare the efficacy and safety of gabapentin, estrogen and placebo in the treatment of hot flashes and other climacteric symptoms.
HRT is associated with an increased risk of thrombo-embolic events, breast cancer and cardiovascular events. Safe, effective, and well-tolerated alternative therapies for hot flashes are needed. Gabapentin is a gamma-aminobutyric acid (GABA)-analog that we have reported is associated with a reduction in the frequency of hot flashes in postmenopausal women who were taking gabapentin for other indications. However, it is not known whether the efficacy of gabapentin in the treatment of hot flashes and other menopausal symptoms is comparable to that of estrogen, the gold standard. For this study, 60 subjects are to be recruited and randomized into 3 arms of 20 each (gabapentin, estrogen and placebo).We will perform an analysis of the results after all 60 subjects have been recruited, screened, enrolled and completed the study. The investigators of the study continue to be blinded to the study groups and their randomization. To determine if gabapentin approaches the efficacy of estrogen in the treatment of hot flashes,postmenopausal women between ages 35 and 60 with 7-20 moderate-severe postmenopausal hot flashes/day will be randomized into a double-blinded placebo controlled trial of estrogen, gabapentin and placebo. All patients must meet stringent inclusion and exclusion criteria. Pre- and post-study hot flash diaries, depression and climacteria scales will be collected. Patients are required to undergo physical examination and blood work and to complete a daily hot flash and medication compliance records. Hot flash frequency and composite score for hot flashes will be calculated for the three groups based on the hot flash diary. Side effects, climacteric scale and depression scales will also be used. ;
