Abstract

Crossing the intestinal mucus layer remains a great hurdle in oral drug delivery. The viscous mucus gel protects the body from pathogens but simultaneously traps many types of delivery vehicles, limiting their therapeutic efficacy. We report the assembly of mucopenetrating PEG-based polymer-lipid hybrid vesicles encapsulated in mucoadhesive alginate carriers aiming to increase their residence time in the intestine. The stability of the formulations was evaluated in simulated gastrointestinal conditions, showing negligible subunit leakage in the gastric fluid but a substantial release in the intestinal fluid. Mucopenetration of the free and encapsulated subunits was first demonstrated in vitro in a microfluidic set-up filled with reconstituted porcine mucus and in a mucus-covered co-culture of Caco-2 cells and HT29-MTX-E12 cells. Finally, the free and encapsulated subunits remained adhered in close proximity to the intestinal epithelium after oral administration to rats while the alginate carriers were washed away. In conclusion, the double-encapsulated system with combined mucoadhesive and mucopenetrating properties is a promising alternative drug carrier for oral delivery.
