Comparison Study of the Effectiveness Between Syndrome Differentiation Treatments and Fixed Formula Treatment for Perimenopausal Syndrome With Chinese Herbal Medicine
Abstract
Background: Perimenopausal syndrome (PMS) refers to a series of symptoms caused by the dynamic fluctuations of sex hormones during menopause. Menopausal symptoms including hot flushes, vaginal dryness and mood swings are experienced by about 80% of Chinese women aged 45 to 60. In the past year, 235 patients visited CMCTR(ND), a TCM center set up by HA and operated by HKFTU Workers' Medical Clinics since 2008, suffered from PMS.
According to literature review, high proportion of clinical trials regarding perimenopausal women used fixed formula treatment. However, different constitutional types were found in perimenopausal women and different fixed formulae were used in different research. Apart from kidney yin deficiency, perimenopausal women were also found in liver-kidney yin deficiency, kidney yang deficiency, kidney yin and yang deficiency, disharmony between heart and kidney, liver qi stagnation, etc. It is difficult to draw a conclusion that any single fixed formula could have the best efficacy on PMS. Therefore, it is worth studying to see whether syndrome differentiation would be a better choice for PMS treatment.
Objective: The study aims to evaluate whether syndrome differentiated treatment is better than fixed formula (Er-Xian decoction) treatment for perimenopausal women.
Design: This is a pilot single-blinded, randomized controlled trial.
Participants: Chinese women aged 45-55 year with menstruation abnormalities (menstrual irregularity in past 12 months; or…
