- Abstract
Bisphosphonates are medicines used to inhibit osteoclastic activity in a number of bone diseases (Paget's disease, osteoporosis, hypercalcemia, primary and secondary hyperparathyroidism, bone metastases). Following in vitro release studies, crystalline hydroxyapatite (HA) was found to be a stable phase in contact with the release medium, and alendronate (AL) bound to HA by the synthesis process was slowly released from the metallic component (titanium) into the release medium for 10 days. Hydroxyapatite after implantation produces chemical species that support the adhesion of the implant to the surrounding tissue forming a functional connective structure. Thus synthesis of the HA-AL composite can be considered as a viable solution for the inclusion of bisphosphonate on the surface of metallic prosthetic components used in orthopedics.
