In 1999 Mundy et al. showed that simvastatin, a drug administered for high cholesterol levels, had a profound stimulatory effect on osteoblasts. Since then other studies have also confirmed that simvastatin enhances bone formation; however, the lack of a local delivery system have restricted its clinical use. We have used premixed acidic calcium phosphate cement as a local delivery system for simvastatin. To confirm that the simvastatin released retained its activity,...

Introduction: A BMP-2-containing premixed calcium phosphate cement (PCPC) could potentially provide the surgeon with an easy-to-handle alloplastic material with osteoinductive properties, accelerating bone ingrowth by stimulating osteogenic differentiation.Methods: The release profile of BMP-2 at 0.05 and 0.50 mg/ml from the PCPC was characterized over a period of 1 week using ELISA.Results: The PCPC released BMP-2 in a biphasic ma...
