Poster Board SAT-509
105 subjects (40-60 yrs) were randomly assigned to either 2mg/d (EQ-2), 6mg/d (EQ-6) or 10mg/d (EQ-10) EQ supplement groups or placebo (P) for 12 wks. Subjects completed the simplified menopausal index (SMI), which is a rating scale for menopausal symptoms including hot flashes (HF) and shoulder stiffness, at 0, 6 and 12 wks. The subjects had ≥25 of SMI score, in which they were categorized as “mild” to “severe” symptomatic. The changes in SMI score at 12 wks were -49.3% in P, -54.1% in EQ-2, -52.8% in EQ-6 and -68% in EQ-10 (P vs EQ-10, p<0.05). Reduction of shoulder stiffness showed EQ dose dependency, with a difference between P vs. EQ-10 for 6 wks (0±0. 4 vs -0.5±0.7, p<0.05) and for 12 wks (-0.3±0.4 vs -1.0±0.9, p=0.06). Thus, EQ-10 was decided to be used as the dosage for the confirmation study.
Since treatment of menopausal symptoms have many placebo effects, over 50% placebo responders in SMI during the 4 wks of screening period were excluded from the treatment period in the confirmation study. 160 subjects (45-60 yrs), who were ≥25 in SMI and ≥1/day in HF, were assigned either P or EQ-10 group for 12 wks. Menopausal symptoms were assessed by multiple instruments including HF frequency record and subscales of the Greene Climacteric Scale. Both severity of HF and neck and muscle stiffness were more improved in EQ-10 vs in P at 12 wks (p<0.05 and p<0.05, respectively). In addition, irritability was reduced by EQ-10 vs. P (p=0.076). HF frequency was reduced in EQ-10 than P (-58.7% vs -34.5%, p<0.01).
These results suggest that 10mg/day EQ supplement alleviates menopausal symptoms, especially in HF and neck/shoulder and muscle stiffness, in EQ non-producing post menopausal Japanese women.
