Abstract:
Valdecoxib has been entrapped in sub-5 microm particles of poly[Lac(Glc-Leu)] copolymer using a oil-in-water (o/w) emulsification-solvent evaporation technique. To achieve monodispersed sized particles, a microfluidizer was used as ultrasonication device. Formulation parameters such as effect of polymer load, ultrasonication time, stabilizer concentration and stirring rate have a profound effect on particle size, and polydispersity. By adjustment of these parameters, microparticles ranging from about 0.8 to more than 4 microm have been prepared.
