Lipid-based formulations (LBF) enhance the oral bioavailability of poorly water-soluble drugs by maintaining them in a solubilized state during digestion. This study aims to establish a robust protocol to evaluate the impact of gastro-intestinal lipolysis on LBF performance, using cinnarizine as a model drug.

In this work, the lipolysis of Labrasol® and Gelucire® 44/14 , two lipid based self-emulsifying drug delivery systems, by pancreatic enzymes and under conditions mimicking the gastrointestinal tract is followed by Taylor dispersion analysis. Results show that, Labrasol® droplets decrease exponentially in size with lipolysis time, whereas Gelucire® 44/14 droplets increased sigmoïdally in size. Even after 120 min lipolysis, both systems maintain a solubilizing capacity of the hydrophobic marker.
