Drug release behavior of beads and microgranules of chitosan.
K. Gupta,M. N. V. Ravi Kumar +1 more
TL;DR: An investigation of the in vitro release kinetics of diclofenac sodium (DFS) from chitosan beads and microgranules and it is found that the percent and amount of the drug release were much higher in acidic solution than in basic solution, probably due to the swelling properties of the matrix at acidic pH.
Journal ArticleDOI
Preparation, characterization and release profiles of pH‐sensitive chitosan beads
K. Gupta,M N V Ravi Kumar +1 more
TL;DR: In this article, spherical crosslinked beads using chitosan, glycine and glutaraldehyde were prepared for controlled release formulations and structural investigation of the beads was made with IR analysis.
Journal ArticleDOI
Semi-interpenetrating polymer network beads of crosslinked chitosan–glycine for controlled release of chlorphenramine maleate
K. Gupta,M. Ravi Kumar +1 more
TL;DR: In this paper, a semi-interpenetrating polymer network beads of chitosan and glycine, crosslinked with different concentrations of glutaraldehyde were prepared for controlled release of drugs.
Journal ArticleDOI
Studies on semi-interpenetrating polymer network beads of chitosan–poly(ethylene glycol) for the controlled release of drugs
K. Gupta,Majeti N. V. Ravi Kumar +1 more
TL;DR: Semi-interpenetrating polymer network beads of chitosan and poly(ethylene glycol) were prepared and characterized for controlled release of drugs in oral sustained delivery system as mentioned in this paper.
Journal ArticleDOI
STRUCTURAL CHANGES AND RELEASE CHARACTERISTICS OF CROSSLINKED CHITOSAN BEADS IN RESPONSE TO SOLUTION pH
K. Gupta,M. N. V. Ravi Kumar +1 more
TL;DR: In this article, a method for preparing beads based on crosslinked chitosan with glutaraldehyde interpenetrating glycine polymer network was described, and their release characteristics were studied using thyamine hydrochloride (Thy-HCl) as a model drug.
