Design a Biodegradable Hydrogel for Drug Delivery System
In this article, we synthesize a novel chitosan -based superabsorbent hydrogel via graft copolymerization of mixtures acrylic acid (AA) and N-vinyl pyrollidon onto chitosan backbones. The polymerization reaction was carried out in an aqueous medium and in the presence of ammonium persulfate (APS) as an initiator and N,N'-methylene bisacrylamide (MBA) as a crosslinker.The hydrogel structures wer...
متن کاملReview: Chitosan Based Hydrogel Polymeric Beads – as Drug Delivery System
Chitosan obtained by alkaline deacetylation of chitin is a non-toxic, biocompatible, and biodegradable natural polymer. Chitosan-based hydrogel polymeric beads have been extensively studied as microor nano-particulate carriers in the pharmaceutical and medical fields, where they have shown promise for drug delivery as a result of their controlled and sustained release properties, as well as bio...
متن کاملStimuli-responsive Hydrogel for Drug Delivery
Introduction Hydrogels have been extensively investigated as drug delivery carriers in biomedical applications.The stimuli-responsive hydrogel is generally created when an ionic monomer is incorporated into the hydrogel network, in which the charged group is formed and called fixed charge since its mobility is much less than that of freely mobile ions within the interstitial fluid. In this stud...
متن کاملFormulation Development and Evaluation of Hydrogel Based Gastroretentive Drug Delivery System of Antihypertensive Drug
Site specific drug delivery has become the important aspect of research. In present study focused has been made to formulate gastroretentive drug delivery (GRDDS) of drugs having narrow absorption window or having good absorption at proximal part of gastrointestinal tract (GIT) to deliver at stomach site. Hydrogel based gastroretentive formulation of ramipril were prepared by gas blowing techni...
متن کاملHydrogel drug delivery system with predictable and tunable drug release and degradation rates.
Many drugs and drug candidates are suboptimal because of short duration of action. For example, peptides and proteins often have serum half-lives of only minutes to hours. One solution to this problem involves conjugation to circulating carriers, such as PEG, that retard kidney filtration and hence increase plasma half-life of the attached drug. We recently reported an approach to half-life ext...
