Sexual function in women on estradiol or venlafaxine for hot flushes: a randomized controlled trial.

ABSTRACT: To evaluate sexual function in midlife women taking low-dose oral estradiol or venlafaxine for hot flushes.In an 8-week randomized controlled trial among women aged 40-62 years, sexual function was compared between 0.5 mg oral estradiol per day or 75 mg venlafaxine per day (both compared with a placebo). Measures included composite and six domain scores from the Female Sexual Function Index and sexually related personal distress.Participants were aged 54.6 years (standard deviation [SD] 3.8) years, 59% white, with 8.1 (SD 5.3) daily hot flushes. Median composite baseline Female Sexual Function Index score was 16.3 (SD 11.9, n=256) for all women and 21.7 (SD 9.3, n=198) among sexually active women. Composite mean Female Sexual Function Index change from baseline to week 8 was 1.4 (95% confidence interval [CI] -0.4 to 3.2) for estradiol, 1.1 (95% CI -0.5 to 2.7) for venlafaxine, and -0.3 (95% CI -1.6 to 1.0) for placebo. Composite Female Sexual Function Index and sexually related distress change from baseline did not differ between estradiol and placebo (P=.38, P=.30) or venlafaxine and placebo (P=.79, P=.48). Among sexually active women, Female Sexual Function Index domain score change from baseline differences (active compared with placebo) in desire was 0.3 (95% CI 0.0-0.6) for estradiol, -0.6 (95% CI -1.2 to 0.0) in orgasm for venlafaxine, and 0.9 (95% CI 0.2-1.6) in penetration pain for venlafaxine. No women reported adverse events related to sexual dysfunction.Overall sexual function among nondepressed midlife women experiencing hot flushes did not change over 8 weeks with low-dose oral estradiol or venlafaxine (compared with placebo), although a subtle increase in desire (estradiol) and decreases in orgasm and pain (venlafaxine) may exist.ClinicalTrials.gov, www.clinicaltrials.gov, NCT01418209.I.

Project description:ObjectivesHot flushes and night sweats (HF/NS) are experienced by 60-70% of menopausal women and are problematic for approximately 20-25%. Potential health risks associated with hormone-replacement therapy (HT) have led to a significant decline in HT use. There is therefore a need for safe, effective and evidence-based alternative treatments for menopausal symptoms. Previous exploratory work suggests that cognitive-behavioural therapy (CBT) is acceptable and effective for women with HF/NS during natural menopause and following breast-cancer treatment. This randomised controlled trial compares the effectiveness of Group CBT and Guided Self-Help CBT with no treatment control in reducing HF/NS Problem Rating and Frequency at post-treatment (main outcome) and at 6 months postrandomisation.Methods and analysis120 women, with 10 or more HF/NS a week for a month, are recruited from GP surgeries and the local community of South London. They are randomised to either 4 weeks of Group CBT, 4 weeks guided Self-Help CBT or no treatment control. Participants attend a clinical interview, and complete baseline questionnaire measures of HF/NS Problem Rating and Frequency (primary outcomes), mood, quality of life, self-esteem, hot-flush beliefs and behaviours, optimism and somatic amplification, and undergo 24 h sternal skin conductance monitoring (SCC-physiological measure of HF/NS) (secondary outcomes). Post-treatment measures (SSC, questionnaires and use of medical services) are collected 6-8 weeks later and follow-up measures (questionnaires and a use of medical services measure) at 6 months postrandomisation.Ethics and disseminationEthical registration was granted by King's College London Research Ethics Committee (ref: PNM/08/09-42). All participants provide written informed consent. If treatment is successful, a Group CBT training manual and training sessions for health professionals, and a Self-Help CBT book will be published. Other CBT delivery options will also be examined (including Computerised Self-Help CBT and Group CBT workshops). Clinical Trial Registration Number ISRCTN57302613.

Project description:Abstract In the phase 3 REPLENISH trial of postmenopausal women with a uterus, TX-001HR (TherapeuticsMD, Boca Raton, FL), an oral 17β-estradiol-progesterone (E2/P4) softgel capsule, reduced moderate to severe hot flush frequency and severity and improved quality of life outcomes, while protecting the endometrium. The objective of this analysis was to further determine the effects of the E2/P4 capsules versus placebo on vasomotor symptoms (VMS) as assessed by the menopause-specific quality of life (MENQOL) questionnaire. In the REPLENISH trial (NCT01942668), women with moderate to severe hot flushes (≥7/day or ≥50/week) were randomized 1:1:1:1:1 to daily E2/P4 (mg/mg) of 1/100 (FDA approved as BIJUVATM), 0.5/100, 0.5/50, 0.25/50, or placebo (VMS substudy). Other women (with fewer VMS) were randomized 1:1:1:1 to active E2/P4 doses only. Three of the 29 items in the MENQOL questionnaire assess vasomotor symptoms: hot flushes, night sweats, and sweating. The symptoms, if experienced, were rated using a 7-item Likert scale ranging from “Not at all bothered” (score of 2) to “Extremely bothered” (score of 8); if not experienced, the score was 1. Changes from baseline to week 12, and months 6 and 12 in these 3 items were assessed in the overall efficacy population (MITT) and VMS (MITT-VMS) substudy population. Women were randomized to daily doses of E2/P4 (mg/mg) 1/100 (n=415), 0.5/100 (n=424), 0.5/50 (n=421), 0.25/50 (n=424) or placebo (n=151). Participants (mean age of 55 years and mean BMI of 27 kg/m2) were primarily white (65%) or black (32%). Mean baseline scores ranged from 6.7 to 7.4 for hot flushes, 6.1 to 7.1 for night sweats, and 6.0 to 6.9 for sweating. In the MITT population, women treated with all E2/P4 doses had significantly more favorable improvements from baseline in their hot flushes (range of significant mean changes with E2/P4 vs placebo, -2.9 to -4.3 vs -1.9 to -2.7), night sweats (-3.1 to -4.0 vs -2.4 to -3.0) and sweating (-2.8 to -3.6 vs -2.3 to -3.2) scores at week 12, and months 6 and 12 (all, P≤0.002). Similarly, significant improvements from baseline with E2/P4 vs placebo (all, P≤0.030) were observed in the MITT-VMS substudy population for hot flushes (-3.0 to -4.4 vs -1.9 to -2.7), night sweats (-3.3 to -4.4 vs -2.4 to -3.0), and sweating (-3.1 to -4.2 vs -2.3 to -3.2), except for those treated with the lowest E2/P4 dose (0.25 mg E2/50 mg P4) at months 6 and 12 for sweating. In the REPLENISH trial, compared with placebo, postmenopausal women treated with E2/P4 had significant improvements in their hot flushes, night sweats and sweating as assessed by MENQOL. Benefits continued for up to 12 months of treatment. These results with this first oral hormone therapy formulation combining bioidentical estradiol and progesterone in a single capsule are consistent with the primary REPLENISH results demonstrating efficacy for the treatment of moderate to severe vasomotor symptoms in menopausal women with a uterus.
