Abstract Oral administration has long been considered the most convenient method of drug delivery, requiring minimal expertise and invasiveness. Unlike injections, it avoids discomfort, wound infections, complications, leading to higher patient compliance. However, effectiveness oral delivery is often hindered by harsh biological barriers gastrointestinal tract, which limit bioaccessibility bioavailability drugs. The development systems (ODDSs) represents a critical area for advancement pharmacotherapy. This review highlights characteristics precise targeting mechanisms ODDSs. It first examines unique properties each compartment, including stomach, small intestine, intestinal mucus, epithelial barrier, colon. Based on these features, outlines strategies design principles ODDSs aimed at overcoming enhance disease treatment. Lastly, discusses challenges potential future directions ODDS development, emphasizing their importance advancing technologies accelerating growth. Graphical

Metabolic diseases like obesity and diabetes are on the rise, therapies with biomacromolecules (such as proteins, peptides, antibodies, oligonucleotides) play a crucial role in their treatment. However, these drugs traditionally injected. For patients chronic (e.g., metabolic diseases), long-term injections accompanied by inconvenience low compliance. Oral administration is preferred, but delivery of challenging due to gastrointestinal barriers. In this article, we introduce available biomacromolecule for treatment diseases. The barriers oral drug strategies overcome also explored. We then discuss alleviating defects, including glucose metabolism, lipid energy such insulin, glucagon-like peptide-1 receptor agonists, proprotein convertase subtilisin/kexin type 9 inhibitors, fibroblast growth factor 21 analogues, peptide YY analogues.

The oral delivery of DNA/RNA nanoparticles represents a transformative approach in immunotherapy and vaccine development. These enable targeted immune modulation by delivering genetic material to specific cells the gut-associated system, triggering both mucosal systemic responses. Unlike parenteral administration, route offers unique immunological environment that supports tolerance activation, depending on formulation design. This review explores underlying mechanisms nanoparticles, their design strategies, recent advances application. Emphasis is placed strategies overcome physiological barriers such as acidic pH, enzymatic degradation, mucus entrapment, epithelial tight junctions. Special attention given role lymphoid tissue mediating responses therapeutic potential these systems platforms, food allergies, autoimmune diseases, chronic inflammation. Despite challenges, nanoparticle support translation technologies into clinical applications for immunomodulation vaccination.
