Raloxifene HCl, a selective estrogen receptor modulator, has been shown to increase bone mineral density (BMD) and decrease biochemical markers of bone turnover in postmenopausal women without stimulatory effects on the breast and uterus. However, it is not known whether the changes in BMD and bone turnover are associated with changes at the tissue level, nor how changes with raloxifene compare with estrogen. In this randomized, double blind study, we evaluated the effects of raloxifene (Evista, 60 mg/day) or conjugated equine estrogens (CEE; Premarin, 0.625 mg/day) on bone architecture, bone turnover, and BMD. Iliac crest bone biopsies were obtained at baseline and at the end of the study after double tetracycline labeling and were analyzed for standard histomorphometric indexes. Serum and urinary biochemical markers of bone turnover were measured at baseline and at 4, 10, 18, and 24 weeks of treatment. Total body, lumbar spine, and hip BMD were measured at baseline and at the end of the study by dual energy x-ray absorptiometry. Activation frequency and bone formation rate/bone volume were significantly decreased from baseline in the CEE, but not in the raloxifene, group. Bone mineralization did not change in either group. Most markers of bone resorption and formation decreased in both groups, but to a greater degree in the CEE group (P < .05). Total body and lumbar spine BMD increased from baseline in both groups, with a greater increase in the CEE group (P< 0.05). Hip BMD significantly increased from baseline in the raloxifene group, but the change was not different from that in the CEE group. These results suggest that raloxifene reduces bone turnover and increases bone density, although to a lesser extent than CEE. Thus, raloxifene is an alternative to CEE for the prevention and treatment of osteoporosis in postmenopausal women.

In recent decades, there has been a clear trend towards an increase in the life expectancy of the population. In the 1990s it reached 78.9 years for women. The global population of postmenopausal women today is 10%. According to WHO projections 46% of women are expected to be over 45 years old by 2015. The age of menopause remains fairly stable and in different regions of Russia is 49-50 years. Consequently, a woman spends more than a third of her life in a state of deficiency of female sex hormones.
