A three-year prospective study was carried out in 283 postmenopausal women to evaluate the effects of a long-acting estriol derivative-nylestriol. The women were randomly assigned into 3 groups: group A (136 cases, nylestriol 2 mg/2 wk), group B (97, nylestriol 1 mg/2 wk) and group C (50, placebo/2wk). LDL-C decreased and HDL-C increased after 3 months of medication (P < 0.05), but TC and TG not significantly changed in any group (P > 0.05). No changes of lipids were found in group C (P > 0.05). Serum ALP, Ca/Cr and Hpr/Cr in fasting urine decreased in 3 months in both group A and B (P < 0.05), but not in group C (P > 0.05). Forearm bone mineral content loss was restrained in groups A and B (P > 0.05), but decreased markedly in group C (P < 0.01). The Kupperman index scores decreased by about 50% after 3 months and 80% in 12 months in groups A and B. Nylestriol induced mild stimulatory effect on the uterine endometrium, and addition of 6 mg of provera daily for 7-10 days every 6 months is recommended. Nylestriol exhibited no obvious effect on the breast. This study demonstrated that nylestriol can be used as an effective and acceptable estrogen replacement therapy for postmenopausal women.

A prospective double-blind study was carried out in 136 women 0.5 to 21 years since menopause (YSM) in order to demonstrate the effects of a long-acting estriol derivative-Nylestriol (CEE3) on bone loss and lipoprotein lipids. They were orally administered at 2 mg of CEE3 or placebo every 2 weeks. Among 90 subjects who finished 1 year of medication, 49 received CEE3 and 41 placebo. The results were: 1. Serum ALP, Ca/Cr and Hop/Cr in fasting urine decreased in 3 months (P < 0.05); 2. Menopause-related reduction of forearm bone density was restrained; 3. LDL-C decreased in 3 months and HDL-C increased in 6 months (P < 0.05), with no significant changes in TC and TG; 4. Side effects were mild. 1/3 of those with intact uterus had spotting and another 1/3 had moderate withdrawal bleeding after the addition of medroxyprogesterone acetate at the end of 12 months of CEE3 therapy. This study demonstrates that CEE3 is effective and acceptable for preventing osteoporosis and lipoprotein lipids disorder in postmenopausal women. Long-term application awaits further studies.
