After 12 weeks, the women reported no significant difference in most bothersome symptoms between estradiol or moisturizing gel, compared with placebo products (P = .25 and P = .31, respectively). The average improvement in symptom scores was similar between the estradiol tablet and placebo tablet (P = .64) and between the moisturizer and placebo gels (P = .17).
The study was limited by several factors including the homogenous population and the absence of a head-to-head comparison of treatments, the researchers noted. However, the results suggest that more research is needed about genitourinary syndrome of menopause, but that a nonprescription lubricating gel may be an appropriate estrogen-free choice, and that “treatment choice should be based on individual patient preferences regarding cost and formulation,” they said.
The study was funded by the National Institutes of Health/National Institute on Aging. Dr. Mitchell is a consultant for Symbiomix Therapeutics, and coauthors reported grant support from Bayer and having served on a scientific advisory board for Sermonix.
