Gelatin Microspheres for the Controlled Release of All-trans-Retinoic Acid Topical Formulation and Drug Delivery Evaluation
A topical o/w cream containing tretinoin microspheres was prepared. Gelatin microspheres of tretinoin were prepared using coacervation method. These microspheres contained about 50% w/w tretinoin. The particle size range of microspheres was between 90-150 m m. In vitro drug release from microspheres and a cream formulation was studied. It was shown that drug release from microspheres followed H...

متن کاملPreparation and characterization of genipin-cross-linked silk fibroin/chitosan sustained-release microspheres
We report the effects of distinct concentrations of genipin and silk fibroin (SF):chitosan (CS) ratios on the formation of SF-CS composite microspheres. We selected microspheres featuring an SF:CS ratio of 1:1, encapsulated various concentrations of bovine serum albumin (BSA), and then compared their encapsulation efficiency and sustained-release rate with those of pure CS microspheres. We dete...
متن کاملFormulation and evaluation of Zidovudine loaded chitosan Microspheres for controlled release
The aim of this study was to formulate and evaluate zidovudine loaded chitosan microspheres for controlled drug release. Microspheres were prepared by emulsification method using gluteraldehyde as crosslinking agent. The prepared microspheres were characterized for their yield and drug loading, as well by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffractometry and Scanning e...
متن کاملFormulation and Evaluation of Cross Linked Chitosan Microspheres Containing Mitomycin-c G.vinoth Kumar*and K.anand Babu
The purpose of this research was to formulate and systematically evaluate in vitro performances of chitosan microspheres containing Mitomycin-C. Chitosan microspheres containing Mitomycin-C were prepared by simple emulsification phase separation technique using glutaraldehyde as a cross-linking agent. Results of preliminary trials indicate that volume of cross-linking agent, time for cross-link...
