Calcium Phosphates / Biphosphonates Combinations…Towards a Therapeutic Synergy

Abstract:

Article Preview

The integration of drugs and devices is a growing force in the medical industry. The incorporation of pharmaceutical products not only promises to expand the therapeutic scope of device technology but to access combination products whose therapeutic value stem equally from both the structural attributes of the device and the intrinsic therapy of the drug. For example, the orthopedic industry is exploring drug-coated hip, knee and bone reconstruction implants capable of promoting healing as an added therapeutic benefit for device recipients. In this context, the drug is eluted locally, being targeted in a specific site of interest, thus offering a convenient strategy to avoid adverse effects commonly observed for systemic treatments of some diseases, as an additional benefit. In addition, these new technologies are generally well adapted to the development of minimally invasive surgery for their implantation. In this context, given the wide use of calcium phosphates (CaPs) and bisphosphonates (BPs) for the therapy of bone-related affections, there was great interest to investigate the chemistry taking place when combining the two systems since: (i) it could provide better insight in the mechanism of BP fixation on bones (ii) such combination could act as efficient BP delivery systems when implanted in bone defects.
