Impact of degree of substitution of acetylated Ofada rice starch polymer on the release properties of nimesulide microspheres [PDF]
Journal of Excipients and Food Chemicals, 2016 Nimesulide microspheres were prepared by the quasi-emulsion solvent diffusion method, using acetylated starches of the indigenous Ofada rice (Oryza glaberrima Steud) with degrees of substitution (DS) 1.42 and 2.62. A full 23 factorial experimental design
