title: Comparison of a triphasic oestradiol/norethisterone acetate preparation with and without an oestriol component in the treatment of climacteric complaints.
abstract: This study was undertaken to evaluate the effects of oestriol in combination with oestradiol in the treatment of women with climacteric complaints. Forty-three post-menopausal women were randomly allocated to two groups on a double-blind basis. Over a 28-day cycle 23 of the women were treated sequentially for 12 days with 1 tablet containing 17 beta-oestradiol 2 mg plus oestriol 1 mg, then for 10 days with 1 tablet containing the same oestrogens plus norethisterone acetate 1 mg, thereafter for 6 days with 1 tablet containing 17 beta-oestradiol 1 mg plus oestriol 0.5 mg. The other 20 women received the same treatment but without the oestriol. No clinical, laboratory or histological differences were seen between the two groups. Both treatments were found to be equally effective in alleviating climacteric symptoms, with few side effects. It may be stated in conclusion that, on the basis of routine clinical and laboratory parameters no differences were found between the two preparations.
