Abstract
Purpose
Whey protein isolate (WPI) has previously been shown to be a promising new excipient for the development of amorphous solid dispersions (ASD) at a high drug loading of 50% (w/w). Whilst WPI is a protein mixture, comprising mainly the three proteins β-lactoglobulin (BLG), α-lactalbumin (ALA), casein glycomacropeptides (CGMP), the individual contributions of these three proteins to the overall performance of whey protein based ASDs has still not been investigated. In addition, the limitations of the technology at even higher drug loadings (i.e., more than 50%) have not yet been explored. In this study, BLG, ALA, CGMP and WPI were each prepared as ASDs with the two poorly water-soluble drugs (Compound A and Compound B) at 50%, 60% and 70% drug loadings.
Methods
Solid state characterization, dissolution rate and physical stability of the obtained samples were analyzed.
Results
All the obtained samples were amorphous and showed faster dissolution rates compared to the respective pure crystalline drugs. However, the BLG based formulations—at least for Compound A—were outperforming the other ASDs in terms of stability, dissolution enhancement and solubility increase.
Conclusion
Overall, the study confirmed that the investigated whey proteins showed their potential in developing ASDs even at high drug loadings of up to 70%.
