determine effects of low-dose estradiol and low-dose venlafaxine on self-reported sleep measures in menopausal women with hot flashes. we hypothesized that low-dose estradiol and low-dose venlafaxine would each be superior to placebo in reducing insomnia symptoms and improving subjective sleep quality and now report the effects of each treatment as compared with placebo on these a priori specified secondary sleep outcomes and examine whether any observed effects varied across risk subgroups defined by participant characteristics measured at baseline. primary analyses consisted of treatment group contrasts between each active treatment group and placebo computed as wald statistics from repeated measures linear regression models summarizing isi and psqi at both 4 and 8 weeks as a function of treatment assignment, clinical center, week number (visit), and baseline value of the sleep outcome measure. clinical improvement at week 8 (≥ 50% decrease from baseline in isi) was observed in 47% of women in the estradiol group, 49% of women in the venlafaxine group, and 35% of women in the placebo group (p active treatment vs. placebo 0.07 for estradiol and 0.04 for venlafaxine).
clinical improvement at week 8 (≥ 50% decrease from baseline in psqi) was observed in 38% of women in the estradiol group, 25% of women in the venlafaxine group, and 18% of women in the placebo group (p active treatment vs. placebo 0.001 for estradiol and 0.20 for venlafaxine). in particular, the trial of the ssri escitalopram that used the isi and psqi to assess sleep reported that treatment with escitalopram compared with placebo reduced isi by 2.0 points and psqi by 1.3 points at 8 weeks—effects nearly identical to those demonstrated with venlafaxine in this study. the effects of low-dose venlafaxine treatment and low-dose estradiol treatment on insomnia symptoms and subjective sleep quality beyond 8 weeks were not evaluated. mean change in isi from baseline to week 8 by treatment assignment overall and within risk subgroups. mean change in psqi from baseline to week 8 by treatment assignment overall and within risk subgroups.

thus, trazodone is probably used for patients who develop not only insomnia, but also inner tension/anxiety during venlafaxine treatment. however, it alleviates nearly one-half of the women in the venlafaxine group versus 35% in the placebo group reported that insomnia symptoms decreased by at least 50% from baseline; both treatment-emergent insomnia and somnolence were the most frequent (both equal to 24%) in patients with generalized anxiety disorders, .
