The study was designed in order the effect of one class of lipophilic statins (Atorvastatin) in some biomarkers of bone formation (Alkaline phosphatase (ALP), 1,25 (OH)2 D3, calcium, and phosphorous) in serum of ovariectomized female rats. Thirty adult female rats (2.5-3) months, weighing (200-220) gm were housed at conditions of controlled temperature (22-25°C), cycle (12h light -12h dark) in the house of animals of Veterinary Medicine College of Mosul University. The animals were divided into three equal groups, sham group, ovariectomized (ovx) group, and ovx treatment orally with 20mg/kg/d of atorvastatin. After 60 days of treatment, blood from all groups was collected for ALP activity, 1,25 (OH)2 D3, calcium, and phosphorous estimation, and left femur bones were excised for histological examination. The results showed that the serum ALP, calcium, and phosphorus were significantly elevated, and a significant reduction in 1,25 (OH)2D3 was noticed in the ovx group. However, treatment with atorvastatin caused a significant reduction in ALP with a non-significant elevation in 1,25 (OH)2D3. Histological results showed a low density and thin trabecular bone, a few blood vessels, high numbers of osteoclast, with low numbers of osteoblasts in the ovx group. However, the treated ovx with atorvastatin increases the thickness of trabecular bone, medium developed osteogenic tissue, and a low number of osteoblasts. In conclusion, atorvastatin has a moderate effect on bone of ovx, affecting bone formation more than bone resorption.
