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 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 کاملDevelopment of Bioadhesive Chitosan Superporous Hydrogel Composite Particles Based Intestinal Drug Delivery System
Bioadhesive superporous hydrogel composite (SPHC) particles were developed for an intestinal delivery of metoprolol succinate and characterized for density, porosity, swelling, morphology, and bioadhesion studies. Chitosan and HPMC were used as bioadhesive and release retardant polymers, respectively. A 3(2) full factorial design was applied to optimize the concentration of chitosan and HPMC. T...
متن کاملHydrogel Advancement: A New Approach for Gastroretentive Drug Delivery
Oral administration of dosage form is the priority for the patients as per its easy administration, economical formulation and various other reasons. Drugs having good absorption in proximal gastrointestinal tract (GIT) part possess bioavailability problem due to less gastric residence time of drug in the stomach. Thus superporous hydrogel (SPH) is a supreme approach to deliver the drug in uppe...
متن کاملAn Overview on Gastroretentive Drug Delivery System
Oral controlled release and site specific drug delivery system has been of great interest in pharmaceutical field to achieve improved therapeutic advantage. Drug absorption in the gastrointestinal tract is a highly variable procedure and prolonging gastric retention of the dosage form extends the time for drug absorption. Gastro retentive drug delivery system is one of such novel approaches to ...
