Chitosan-pectin complexes: a new frontier in biopolymer-based drug delivery systems

Natural polysaccharides like pectin and chitosan have attracted a lot of attention in biopolymer research because of their diverse range of possible uses and special physicochemical characteristics. Each polymer has advantageous qualities on its own. For example, pectin is known for its gelling ability and biocompatibility, while chitosan is recognized for its antibacterial, mucoadhesive, and biodegradable qualities. Through electrostatic interactions between the negatively charged carboxyl groups of pectin and the positively charged amino groups of chitosan, these biopolymers join to form a chitosan-pectin complex. When compared to the separate polymers, this combination produces a flexible and structurally stable material with improved mechanical strength, stability, and biocompatibility. The chitosan-pectin complex is a great option for a variety of drug delivery applications because of its advantageous physicochemical characteristics, which include pH responsiveness and regulated drug release. These include oral tablets, hydrogels, films, and nanoparticles, where the complex can enhance therapeutic efficacy and allow for the targeted administration of drugs to specific sites in the body. Notably, this biopolymer system exhibits significant promise for improving prolonged drug release characteristics, lowering adverse effects, and increasing bioavailability. With an emphasis on their uses in cutting-edge drug delivery systems, this review attempts to provide a thorough understanding of the synthesis techniques and structural features of chitosan-pectin complexes. It also looks at new developments and potential application of chitosan-pectin-based polymers in the biomedical and pharmaceutical industries.
