Osteoporosis is one of the most common chronic skeletal disorders, particularly among postmenopausal women, and is associated with an increased risk of fragility fractures, disability, and reduced quality of life. Several preclinical studies and retrospective clinical studies have suggested that statins may exert beneficial effects on bone metabolism by promoting bone formation and reducing bone resorption. Since osteoporosis and hyperlipidemia frequently coexist in postmenopausal women, the concomitant use of statins with standard osteoporosis therapy may provide dual clinical benefits by improving both skeletal and cardiovascular outcomes. In this prospective interventional study, atorvastatin and Rosuvastatin was administered according to current clinical practice guidelines only to participants with an indication for statin therapy, defined as an atherosclerotic cardiovascular disease (ASCVD) risk score of ≥5%. The effects of standard osteoporosis therapy alone (alendronate, calcium, and vitamin D) were compared with those of standard therapy plus atorvastatin and compared with those of standard therapy plus rosuvastatin. The study aims to evaluate the effect of adjunctive statin therapy on bone mineral density and biochemical markers of bone turnover, including markers of bone formation and bone resorption, in postmenopausal women with osteoporosis.
