The aim of this study is to explore the efficacy of Guizhifulingwan (GFW) in the treatment of climacteric syndrome in women.


This is a single-center, randomized, placebo-controlled, parallel-group design pilot trial. Fifty participants with climacteric syndrome will be randomly allocated to the GFW or placebo group in a 1:1 ratio. The participants will be administered GFW or placebo granules three times a day for 4 weeks and will be followed up for a further 4 weeks. The primary outcome is the mean change in menopause rating scale score at 5 weeks after randomization. Secondary outcomes include the World Health Organization quality of life-BREF scores, degrees of upward movement of qi and lower abdominal resistance and tenderness, blood stasis pattern questionnaire scores, and results of blood tests including assays for lipid profile, high sensitivity C-reactive protein, follicle-stimulating hormone, and estradiol. The feasibility outcomes include recruitment and completion rates and adherence to medication.


The results of this study will provide basic data for the design of a large-scale clinical trial for evaluating the efficacy of GFW in the treatment of climacteric syndrome in women.
