Directed Hydrothermal Synthesis of Aluminosilicates of Various Structural Types and Prospects for Their Use in Medicine

The results of analysis and experimental studies of the possibilities of using synthetic aluminosilicates (montmorillonites, kaolinites, zeolites) in medicine, in particular in the field of entero- and hemosorption, in the development of targeted drug delivery systems with prolonged and pH-controlled release of the active substance in various environments, as well as components of wound dressings are presented. Montmorillonites, aluminosilicates of the kaolinite subgroup with different particle morphologies and zeolites of structural types Beta, Rho and Y were obtained under hydrothermal conditions and characterized by a complex of physicochemical research methods. The results of studying the adsorption and desorption of model drugs (thiamine hydrochloride, 5-fluorouracil) from porous aluminosilicate matrices of various chemical compositions in various media simulating body environments, adsorption of markers of endogenous intoxication (methylene blue), the ability of aluminosilicates to biodegrade in body environments, and also studies of biological activity, in particular cytotoxicity and hemolytic activity of synthetic aluminosilicates are presented. The results obtained show significant prospects for the use of synthetic aluminosilicates to obtain non-toxic, highly effective sorbents for medical use and drug carriers.
