Advances in superporous hydrogels.

چکیده
Superporous hydrogels (SPHs) are different from superabsorbent polymers (SAPs) in that SPHs swell fast, within minutes, to the equilibrium swollen state regardless of their size. The fast swelling property is based on water absorption through open porous structure by capillary force. The poor mechanical strength of SPHs was overcome by developing the second-generation SPH composites (SPHCs) and the third-generation SPH hybrids (SPHHs). This review examines the differences between SAPs and SPHs and describes three different generations of SPHs.

Development of a Gastroretentive Drug Delivery System based on Superporous Hydrogel
Purpose: The aim of this work was to synthesize superporous hydrogels of rosiglitazone using chitosan and to study its swelling behaviour for application as a gastroretentive drug delivery system. Methods: Chitosan superporous hydrogels were synthesized using glyoxal as a crosslinking agent by gas blowing method. The effect of pH and ionic strength on the swelling ratio was determined. Swelling...
متن کاملDrug delivery applications for superporous hydrogels.
INTRODUCTION Considerable advances have been made to hydrogels with the development of faster swelling superporous hydrogels (SPHs). These new-generation hydrogels have large numbers of interconnected pores, giving them the capacity to absorb large amounts of water at an accelerated rate. This gives SPHs the ability to be used in a variety of novel drug delivery applications, such as gastric re...

متن کاملPreparation and characterization of superporous hydrogels as gastroretentive drug delivery system for rosiglitazone maleate
BACKGROUND AND THE PURPOSE OF THE STUDY Many drugs which have narrow therapeutic window and are absorbed mainly in stomach have been developed as gastroretentive delivery system. Rosiglitazone maleate, an anti-diabetic, is highly unstable at basic pH and is extensively absorbed from the stomach. Hence there is a need to develop a gastroretentive system. In this study a superporous hydrogel was ...
