The primary objectives were to prolong drug delivery, reduce sudden releases, and enhance the overall quality and stability of DepoFoam. The research hypotheses are centered on the capability of macrogol-based surface modification to create an optimized drug delivery system with improved stability, extended drug release, and enhanced pharmacokinetic properties.</p><h3>Methods</h3><p>In this research, surface remodeling was achieved through a series of processes, including high-shear homogenizer-assisted double emulsification, PEGylation, and purification.

Increased crosslinker concentration showed a slightly smaller IPN hydrogel bead mean diameter and increased encapsulation of loaded drug to about 88 to 91% glipizide. The in vitro drug dissolution was observed to be slower with increased xanthan gum polymer and calcium ion crosslinker concentration, which extended the drug release to 14 h.
