EN The drugs most commonly used in the treatment of osteoporosis are bisphosphonates. This disease results in low mineral density and a weakened bone microstructure. The delivery methods for these drugs have many disadvantages, and new ones are being searched for. In this work, biocompatible zinc titanate coated titanium implants were obtained as potential new carriers for drugs. Such a material will release the drug, and it will have antibacterial properties. Gradual release of the bisphosphonate will have a positive effect on the recovery process and osteointegration. In addition, the drug will be released around the affected bones. The effectiveness of the modification and attachment of the drug was confirmed by SEM, XPS, EDS, FT-IR imaging, and UV–VIS. It was shown that the risedronate could be almost completely released upon contact with body fluids within a week. The drug is evenly distributed over the entire surface of the alloy as confirmed by FT-IR imaging. The results presented in this work will allow for the preparation of endoprostheses that release the drug and have antibacterial properties.
