Oral administration of low permeable drugs remains a challenge as they do not cross biological membrane efficiently and therefore exhibit a poor bioavailability. Herein, the effect of magnetic retention on the circulation and bioavailability of magnetic beads in the gastrointestinal tract in the presence of an external magnetic field is evaluated.

This work reports the synthesis and performance of magnetic chitosan-alginate core-shell beads for oral administration of small molecules in order to increase their bioavailability. For this purpose, we designed magnetic core-shell beads suitable for oral delivery that are resistant in acidic media (stomach pH), mucoadhesive, exhibit a superparamagnetic(More)
