Xanthan gum in drug delivery

This chapter explores the versatile uses of xanthan gum (XG) in the formulation of drug delivery systems (DDSs). XG, a natural polysaccharide derived from Xanthomonas campestris, has received significant attention from the pharmaceutical industry because of its unique rheological properties, biocompatibility, and mucoadhesive nature. The contribution provides an overview of this biopolymer, its structure, properties, and various formulations used in drug delivery. It discusses the role of XG in the development of sustained-release formulations, targeted DDSs, mucoadhesive drug carriers, and nanoparticulate systems. In addition, the chapter highlights recent advances, challenges, and future perspectives in utilizing XG to improve drug delivery efficiency and therapeutic outcomes.
