Effect of Tissue-Selective Estrogen Complex on Hip Structural Geometry in Postmenopausal Women: A 12-Month Study

Bazedoxifene plus conjugated estrogens improve menopausal symptoms in postmenopausal women: a systematic review and meta-analysis

Our aim is to evaluate the efficacy of bazedoxifene (BZA) plus conjugated estrogens (CE) on menopausal symptoms in postmenopausal women. A series of databases including PubMed, EMBASE, Medline, Web of science, China national knowledge internet and Wanfang database up to 31 October 2021 were searched, and randomized controlled trials (RCTs) of BZA/CE for menopausal symptoms were included. Seven RCTs involving 5431 patients were included in this study. Compared with placebo group, there were significantly reduce in daily number of hot flushes, daily number of moderate or severe hot flushes, the percentages of parabasal cells and the time to fall sleep when patients treated with BZA/CE. Besides, there were significant improvement in sleep disturbance and total MENQOL. However, no significant improvements in sleep adequacy were observed in the three groups. Furthermore, BZA 20 mg/CE 0.625 mg was more effective than BZA 20 mg/CE 0.45 mg in improving the menopausal symptoms. Therefore, both bazedoxifene 20 mg plus conjugated estrogens 0.45 mg and bazedoxifene 20 mg plus conjugated estrogens 0.625 mg could significantly improve the menopause-related symptoms and MENQOL in postmenopausal women, and the curative effects of BZA 20 mg/CE 0.625 mg were better than that of BZA 20 mg/CE 0.45 mg. These findings need to be further confirmed by more high-quality RCTs.
