There have been major advancements in the treatment of inflammatory bowel disease (IBD) over the past three decades. However despite significant progress, the best available treatments continue to demonstrate variable efficacy in patients and are associated with adverse effects. Therefore there remains an unmet clinical need for ongoing therapeutic advances for IBD. In recent years nanomedicines have emerged as promising diagnostic and therapeutic tools. Nanoparticles in particular show promise to facilitate targeted oral drug delivery in IBD. Here we discuss the pitfalls of current therapies and explore the potential for nanoparticles to improve the treatment of IBD. This review examines the range of conventional and novel therapies which have benefited from nanoparticle-mediated delivery and highlights the proven therapeutic efficacy of this approach in preclinical models. These strategies under development represent a novel and innovative treatment for IBD.
