Аннотация: Anemia is a global health problem that affects both adults and children, but treatment is hampered by serious side effects, primarily associated with the gastrointestinal tract with oral administration of drugs. In this study, we aimed to develop an oral form of iron compounds using polymethylsilsesquioxane hydrogels. To boost loading efficiency and prolong release, the iron compounds (FeCl3 and ferrous D-Gluconate) are incorporated into a guest–host complex with 2-hydroxypropyl-beta-cyclodextrin. We used PRXD, SEM, EDX mapping, and FTIR to investigate the complex formation, as well as the incorporation of such complexes into hydrogels. The optimal system underlines a combination of ferrous D-Gluconate and HPCD in a 1:1 molar ratio, embedded into a hydrogel with a modest quantity of silicate crosslinks. We demonstrated the slowing of iron release in a gastric media. Mathematical investigation revealed that the Higuchi mechanism releases iron from the hydrogel.
