Abstract:
The purpose of this study is to fabricate 5-Fluorouracil sustained release matrix based on a novel, nontoxic, eco-friendly modified biopolymer. The sesbania gum based hydrogel has been prepared by microwave assisted method using acrylamide as a monomer and N,N Methylenebisacrylamide as a crosslinker. The crosslink copolymerization has been confirmed by several modern techniques such as FTIR, SEM, XRD, TGA, DSC, elemental analysis etc. The bioactive 5-Fluorouracil has been encapsulated via solvent swelling method and its release rate has been investigated in various pH dissolution medium through USP standard protocol. The synthesized hydrogel with higher degree of crosslinking exhibited slower release rate than that of hydrogel having lower degree of crosslinking. Thus, resulting higher t25 value, the release rate increases with increase in pH of the medium. Release kinetics suggests the non-Fickian release behaviour of the hydrogel.
