The effect of tibolone versus 17beta-estradiol on climacteric symptoms in women with surgical menopause: a randomized, cross-over study.

OBJECTIVE

To compare the effectiveness of tibolone and 17beta-estradiol on climacteric symptoms, in a randomized, single-blind, cross-over study in surgically menopausal women.

MATERIAL AND METHODS

Forty surgically menopausal women were divided randomly into two groups. Group A received treatment with tibolone for 6 months, while group B received 17beta-estradiol. After 3 weeks washout period, treatment protocols were exchanged for another 6 months. The climacteric symptoms were assessed with Greene Climacteric Scale at baseline, during washout and after the treatments. Statistical analysis was done with the Wilcoxon's Sign Rank test.

RESULTS

Both treatments significantly improved the scores of all subscales with respect to baseline. However, the improvement in psychological, somatic and sexual subscales were significantly superior in the tibolone group compared with 17beta-estradiol group. Both treatments showed comparable improvements in the relief of vasomotor symptoms.

CONCLUSION

Our findings suggest that tibolone may improve mood, libido and somatic symptoms in surgically menopausal women to a greater extent than estrogen therapy alone.
