TL;DR: In this article, the role of dynamic swelling and the dissolution of the polymer matrix on the release mechanism was discussed, as well as the effect of the tracer/excipient ratio on the poly(vinyl alcohol) release profile.

TL;DR: The aim of this review is to give an insight into the many potential applications of chitosan as a pharmaceutical drug carrier.

TL;DR: In this article, the nature of the adhesive interface, the surface roughness, the chemical structure of the bioadhesive-candidate material, the swelling (hydration) at the adhesive interfaces, and the dynamic development of the bond strength are analyzed in terms of molecular and surface theories.

TL;DR: The authors firstly review the literature dealing with drug absorption sites in the gastrointestinal tract, and descriptions are given of the methods used in determining the location of these sites, and the advantages and disavantages of each method are critically discussed.

TL;DR: The mucoadhesive polysaccharide chitosan was evaluated as a potential component in ophthalmic gels for enabling increased precorneal drug residence times and showed excellent tolerance after topical administration onto the corneal surface.
