Abstract

OBJECTIVE:

This study is a phase II clinical trial that aims to investigate the dose-response relationship of a Chinese herbal medicine preparation, Dang Gui Buxue Tang (DBT), with short-term menopausal symptoms and quality of life in local postmenopausal women.

METHODS:

A randomized, double-blind, multiple-dose escalation trial was performed in 60 postmenopausal women experiencing severe hot flashes and night sweats. The participants were randomized to receive DBT preparations at 1.5, 3.0, or 6.0 g/day for 12 weeks. The primary outcomes were vasomotor symptoms, Greene Climacteric Scale (GCS) score, and Menopause-Specific Quality of Life (MENQOL) score. Secondary outcomes included serum hormones and lipids.

RESULTS:

There were between-group differences in psychological/psychosocial (P = 0.015, GCS; P = 0.013, MENQOL) and somatic/physical (P = 0.019, GCS; P = 0.037, MENQOL) domains, and improvement was significantly greatest (P < 0.05) in the 6.0 g/day dose group. The frequency and severity of hot flashes and night sweats were significantly reduced in the 3.0 g/day (14.5%-21.2%, P < 0.05, hot flashes; 28.6%-39.6%, P < 0.05, night sweats) and 6.0 g/day (34.9%-37.4.0%, P < 0.01, hot flashes; 10.1%-12.8%, P < 0.01, night sweats) dose groups. The female hormones follicle-stimulating hormone, luteinizing hormone, and 17β-estradiol, as well as the lipids total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol, were not significantly different within groups and between groups.

CONCLUSIONS:

DBT preparations at 6.0 g/day significantly improve physical and psychological scores and significantly reduce vasomotor symptoms from baseline. The treatment was well tolerated, with no serious adverse events noted during the 12-week intervention period. The changes do not affect hormones and lipid profiles.
