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.

In this study the size of microemulsion droplets is carried out using Tailor Dispersion Analysis in comparison to Dynamic Light Scattering. The size evolution of a Labrasol® self emulsifying drug delivery system as a function of concentration and temperature is evaluated. The influence of physical parameters and polydispersity is discussed.
