Kostní cementy na bázi fosforečnanu vápenatého: Syntéza, charakterizace a vlastnosti uvolňování léčivé látky / Calcium phosphate bone cements: Synthesis, Characterization and drug release properties

Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Technology Author: Jiří Doubek Supervisor: Dr. Georgios Paraskevopoulos, Ph.D. Title of Thesis: Calcium phosphate bone cements: Synthesis, characterization and drug release properties Non-healing bone traumas are currently a complication, which may disable a patient from active life for a long period. Due to the fact that bone mass consists mostly of hydroxyapatite, a derivative of calcium phosphate - calcium phosphate cement (CPC) - is studied as an injectable bone substitute. The cement's characteristics (low setting temperature, injectability, bioactivity, and resorbability) are very promising. Furthermore, the possibility to incorporate a drug in the formulation that would support the healing process opens a way for new therapeutic options. Firstly, the aim of this research was to synthesize a high-quality α-tricalcium phosphate (α-TCP) and characterize its properties. Subsequently, the prepared α-TCP was used for the preparation of an injectable and washout resistant cement paste. Finally, the properties of developed pure or ibuprofen-loaded cement were examined by X-ray diffraction, Raman spectra, compressive strength, scanning electron microscopy, and dissolution studies. The obtained data revealed that...
