Accessing amorphous solid dispersions for improved Solubility and Bioavailability in paediatric applications

Introduction
- BCS class II drugs show a low solubility. Modern paediatric formulations are needed to obtain high acceptance of patients at recommended daily doses
- Hot-melt extrusion (HME) and Spray Drying (SD) are the standard preparation techniques for ASD formulation attempts [1]
- Both products are not direct processable to capsules and need further preparation [2,3]
Objectives
- Investigating two alternative fluid bed systems for the preparation of a free-flowing product for further processing (e.g., filling into capsules)
- Layering an ASD on beads in a Fluid-Bed-Wurster
- In-situ SD and agglomeration in a Spouted Bed
Materials
- 40 % (w/w) Nifedipine as model BCS Class II drug
- 60 % (w/w) Kollidon VA64, a Vinyl-pyrrolidone/vinyl-acetate copolymer
- Solvent: Acetone
- Manufactured in a Glatt Wurster-System and ProCell-Labsystem (Glatt Ingenieurtechnik GmbH, Germany)
Characterization of the ASDs
SEM Images
Conclusion
- Both techniques proved to be promising tools for thedevelopment and manufacturing of ASDs
• Stable over a long time (up to 2 yrs.)
• Good flow properties for further processing to e.g. capsules - Good dissolution performance
- Up-scaling to pilot or production scale possible
- Suitable for batch and continuous process design
