Inflammatory bowel diseases(IBD)significantly contribute to high mortality globally and negatively affect patients'qualifications of life.The gastrointestinal tract has unique anatomical characteristics and physiological environment limitations.Moreover,certain natural or synthetic anti-inflammatory drugs are associated with poor targeting,low drug accumulation at the lesion site,and other side effects,hindering them from exerting their therapeutic effects.Colon-targeted drug delivery systems represent attractive alternatives as novel carriers for IBD treatment.This review mainly discusses the treatment status of IBD,obstacles to drug delivery,design strategies of colon-targeted delivery systems,and perspectives on the existing complementary therapies.Moreover,based on recent reports,we summarized the therapeutic mechanism of colon-targeted drug delivery.Finally,we addressed the challenges and future directions to facilitate the exploitation of advanced nanomedicine for IBD therapy.
