HYDROGELS BASED ON NATURAL POLYMERS STRUCTURED WITH PROPYLENE GLYCOL DIEPOXIDE FOR DRUG DELIVERY

The article presents the conditions of synthesis and the results of characterization of the obtained gelatin and gelatin-alginate hydrogels structured with polypropylene glycol diepoxide. The swelling in water, saline, and model exudate was studied, and the gel fraction and tensile strength of the synthesized samples were determined. The regularities of saturation with drugs and their release into model environments were obtained.

Possibility of Using Embolizing Preparation Derived from Poly(2-Hydroxyethyl Methacrylate) (Poly-HEMA) for Chemoemobolization

The principal opportunity of uptaking weakly crosslinked hydrogel emboli is shown by Doxorubicin at different temperatures. The optimal process time is 1.5–2.5 h. It is revealed that Doxorubicin is capable to diffuse from a polymeric matrix, having targeted medical effect on surrounding tissue and reducing side impacts on other organs.
