Optimization of polymeric nano drug delivery system using 3(2) full factorial design.

This study investigated the utility of a 3(2) factorial design and optimization process for nanoparticle suspension prepared by two different polymers Eudragit(®) RS 100 and Eudragit (®) RL 100 respectively. Total 18 formulations (9 formulations with each polymer) were prepared by solvent displacement technique. In these designs, two factors namely polymer weight (X1) and Aq.
