Multifunctional injectable thermo-/pH-responsive hydrogels as release systems for the oral
delivery of small molecule drugs and the local delivery of protein are presented. The …

This study evaluated the potential of stimuli-responsive bacterial cellulose-g-poly (acrylic
acid-co-acrylamide) hydrogels as oral controlled-release drug delivery carriers. Hydrogels …

This paper reports new formulations based on chitosan, citral, and diclofenac sodium salt
(DCF). The central idea was to encapsulate an anionic drug into a polycationic hydrogel …

The aim of this study was to develop a controlled release system targeting antibiotic delivery
to the stomach. The hydrogels were synthesized by using chitosan, poly (acrylic acid) and …

Controlled drug delivery is gaining importance over the conventional methods of drug
administration because of its inherent benefits. Self-regulated release from the delivery …

In this study, central composite design was utilized for the preparation and optimization of
chitosan-gelatin hydrogel films containing metformin using different concentrations of …

The new polyelectrolyte complex gel beads based on phosphorylated chitosan (PCS) were
developed for controlled release of ibuprofen in oral administration. The PCS gel beads …

Effective oral delivery of proteins is impeded by steep pH gradients and proteolytic enzymes
in the gastrointestinal tract, as well as low absorption of the proteins into the bloodstream …
