ABSTRACT

The present research work was aimed to synthesize neem gum-based site-specific drug delivery device for anticancer drug methotrexate at different pH condition. The hydrogel-based drug delivery device was synthesized by optimizing reaction parameters using a factorial design approach response surface method. This model comprised of various sets of reactions with varying concentrations of solvent, crosslinker, initiator and monomer under microwave radiation. Characterization of the candidate hydrogel was done using UV-visible spectrophotometer, FTIR, SEM, Raman, and XRD techniques. The release profile of the hydrogels network was studied through a methotrexate under different pH conditions. The drug encapsulation capacity was found to be around 93% and 90% in pH 7.4 and 6.8. Drug release through the synthesized hydrogel matrix was found to show non-Fickian behaviour at each medium. The hydrogel network showed less release in pH 6.8 than pH 7.4, suggesting that hydrogels may be suitable drug carriers for release of anticancer drug delivery system. Hemolysis testing was also done to check the compatibility of the synthesized drug delivery device with the four different blood samples. Hemolysis was found to be less than 1% in the case of all blood groups, which indicates that the synthesized candidate polymers are biocompatible with all blood groups.
