To regulate the drug delivery, solid inclusion complexes (ICs) of IBF in β−cyclodextrin (β−CD) were prepared and added to the hydrogels. The ICs were prepared by the microwave irradiation method, which is environmentally more benign method. The formation of IC was confirmed by various analytical techniques and the synthesized hydrogels were also characterized. Controlled release of drug was achieved from the hydrogels containing the ICs in comparison to the rapid release from hydrogels containing free IBF. The preliminary kinetic analysis emphasized the crucial role of β−CD in the drug release process that influences the polymer relaxation, thereby leading to prolonged release. The cytotoxicity assay validated the hydrogels as non-toxic in nature and hence can be utilized for controlled delivery of IBF.
