Beyond nanoparticles, various other formulation technologies being adopted for oral delivery of proteins and peptides are showing promise. This includes the development of enteric coated capsules or tablets designed to protect the active pharmaceutical ingredient from the acidic environment of the stomach and release it in the more alkaline conditions of the intestine. Innovative approaches also encompass the creation of smart oral delivery systems, such as those that respond to specific physiological cues for targeted release. The development of oral films as breakthrough tools for oral delivery of proteins is another area gaining traction, offering a convenient and potentially more efficient route of administration.

The challenges inherent in oral protein and peptide drug delivery are multifaceted. These include enzymatic degradation in the stomach and intestine, poor permeability across the intestinal epithelium, and the rapid clearance from the gastrointestinal tract. To address these, researchers are exploring a range of strategies. Absorption enhancers, enzyme inhibitors, and mucoadhesive polymers are being incorporated into formulations to improve the absorption of peptides and proteins. Additionally, modifications to the protein and peptide molecules themselves are being investigated to enhance their stability and suitability for oral administration.

The exploration of materials for oral delivery of proteins and peptides is a dynamic and rapidly advancing field. Beyond the aforementioned technologies, other carbohydrate polymers like anionic carboxymethyl starch and cationic quaternary ammonium compounds are being utilized for targeted delivery to specific regions of the gastrointestinal tract. Researchers are also investigating the potential of emulsions, hydrogels, and biocompatible and biodegradable polymeric nanocarriers as effective platforms.WO2008132727A2 - Oral delivery of proteins and peptides The ultimate goal is to achieve reliable and efficient protein and peptide oral delivery, making these vital therapeutics more accessible and convenient for patients.
