Comparing the effect of adding Gelucire® 48/16 and Gelucire® 50/13 in amorphous solid dispersion: a case study with ticagrelor
CRS - Jul 2024
When amorphous solid dispersion (ASD) are produced by hot melt extrusion (HME), the use of a neat polymer requires high process temperatures, and the drug release is not always complete. Adding Gelucire® in the formula is a promising strategy to address these issues.
Advantages of combining polymers and lipids in extrusion processes
PBP - Mar 2024
Lipid excipients lower the glass transition temperature of polymers, enabling hot-melt extrusion at lower engine torque for better processability. Different polymers and lipid combinations have been tested to explore their potential in extrusion processes.

Solid lipid excipients: born to be extruded!
Nov 2014
Functional excipients are critical to the successful application of HME to resolve formulation challenges. Whilst polymers show potential in both controlled release and in improving the solubility and dissolution of poorly soluble compounds they are not ideal materials for extrusion. Lipid excipients are distinctly different to polymers and behave differently in HME. This article highlights two glyceride-esters: Compritol® 888 ATO and Precirol® ATO 5. They melt at relatively low temperatures and recrystallize quickly. They extrude well and can produce strand-like extrudates which can be down streamed into powders or granules.
These glyceride-esters can be used as release retarding agents/dissolution modifiers for both insoluble and soluble drugs even for high drug loading. In combination with plastic polymers they also can act as plasticizer/processing aid enabling lower temperature process and continuous production.
At Gattefossé we aim to share our knowledge to help formulators use lipid excipients to their best advantage.
