Method & Evidence

AimTo investigate and compare the effectiveness of granulation versus liquid mixing methods for solidifying fenofibrate nanocrystal suspensions, focusing on maintaining critical quality attributes like particle size and dissolution rate.

MethodComparative experimental study

ProcedureFenofibrate nanocrystal suspensions were prepared using wet milling. Two solidification methods were then applied: liquid mixing and granulation (involving dry powder blending and wet massing). The process involved adsorbing the fenofibrate onto Florite® to prevent aggregation. Critical quality attributes (particle size, dissolution rate) were assessed. Spectroscopic and thermal analysis techniques (IR, XRD, DSC, SEM) were employed to monitor the drug's physical state. The solidified powders and resulting tablets were evaluated.
