Research Area: Cancer Biological Activity: Raloxifene has estrogen and tamoxifen-like effects on bone and serum cholesterol levels in ovariectomized rats. At 5 weeks, ovariectomy induced a 9% and 18% decrease in the bone mineral density of the lumbar vertebrae L1-4 and proximal tibiae, respectively. Raloxifene prevented this loss of bone with EC50=0.3 mg/kg/day for both the axial and appendicular skeleton.
