Abstract
Injectable hydrogel-based materials have emerged as promising alendronate (ALN) delivery systems for the treatment of osteoporosis. However, their intrinsic permeability limits the sustained delivery of small-molecule drugs. In response to this challenge, we present the multifunctional hybrids composed of mesoporous silica particles decorated with hydroxyapatite and loaded with alendronate (MSP-NH2-HAp-ALN), which are immobilized in collagen/chitosan/hyaluronic acid-based hydrogel. We have mainly focused on the biological in vitro/ex vivo evaluation of developed composites. It was found that the extracts released from tested systems do not exhibit hemolytic properties and are safe for blood elements and the human liver cell model. The resulting materials create an environment conducive to differentiating human bone marrow mesenchymal stem cells and reduce the viability of osteoclast precursors (RAW 264.7). Importantly, even the system with the lowest concentration of ALN caused a substantial cytotoxic effect on RAW 264.7 cells; their viability decreased to 20 % and 10 % of control on 3 and 7 day of culture. Additionally, prolonged ALN release (up to 20 days) with minimized burst release was observed, while material features (wettability, swellability, degradation, mechanical properties) depended on MSP-NH2-HAp-ALN content. The obtained data indicate that developed composites establish a high-potential formulation for safe and effective osteoporosis therapy.
