OBJECTIVE To prepare vinpocetine(VP)micelles by using an amphiphilicβ-CD derivative,β-CD-[P(AA-coMMA)-b-PNVP]4(β-CD-PPP);and to explore its potential application in drug delivery system.METHODS VP micelles were prepared by solvent evaporation methods and the preparation process of VP micelles was optimized by single factor analysis and orthogonal test.The drug loading capacity,entrapment efficiency,particle size,the in vitro release of VP micelles,and the critical micelle concentration(CMC)ofβ-CD-PPP were d...
