RESUMO
Two-hundred and fourteen (214) menopausal women with moderate to severe vasomotor symptoms, aged 40-65 years, were randomised. After a 4-week treatment-free period, each women received a continuous regimen of Menorest 50 twice weekly or Premarin 0.625 mg daily, for 12 weeks. Didrogesterone 10 mg was also given to all women for 12 days of every 28-day cycle. The objectives were to compare the efficacy and safety profiles of Menorest and an oral estrogen. A statistically significant reduction in the mean number of hot flushes occurred in each group compared to baseline with a decrease from 7.1 at baseline to 0.9 at 12 weeks in the Menorest group, and from 6.7 to 0.5 in the oral estrogen group; there was no statistically significant difference between the two groups (P = 0.36). With each successive treatment cycle, there was a continuous improvement in the number of hot flushes. The incidence and severity of menopausal symptoms were reduced in the same manner in both groups. There were no statistically significant differences in the mean plasma estradiol and estrone concentrations between the two treatment groups after 10 weeks of therapy. The mean estradiol to estrone ratio was similar in both groups, as was the number of adverse events observed. In summary, Menorest was as effective as an oral estrogen in alleviating menopausal symptoms.
