The oral bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs) can be improved by the preparation of amorphous solid dispersions (ASDs) where the API is dissolved in polymeric excipients. Desired properties of such ASDs like storage stability, dissolution behavior, and processability can be optimized by additional excipients. In this work, the influence of so-called low-molecular-weight excipients (LMWEs) on the phase behavior of ASDs was investigated.

Simulation of HME processes is a valuable tool for increased process understanding and ease of scale-up. However, the experimental determination of all required input parameters is tedious, namely the melt rheology of the amorphous solid dispersion (ASD) in question.
