New drug delivery technologies are essential for poorly soluble drugs. Amorphous solid dispersions (ASDs) using polymers like Kollidon® VA 64 and Soluplus® enhance solubility and bioavailability, with advanced manufacturing methods improving stability.
Area of Science:
- Pharmaceutical Science
- Materials Science
Background:
- Growing number of poorly water-soluble drug candidates necessitates advanced formulation technologies.
- Amorphous solid dispersions (ASDs) offer enhanced solubility and controlled release but face stability challenges.
- Understanding polymeric excipients is crucial for developing stable ASDs.
Purpose of the Study:
- To review the application of Kollidon® VA 64 (copovidone) and Soluplus® in ASD manufacturing over the past 20 years.
- To explore both classical and advanced manufacturing technologies for ASDs.
- To highlight the role of these polymers in enhancing solubility and bioavailability of poorly soluble drugs.
Main Methods:
- Review of scientific literature on ASDs, Kollidon® VA 64, and Soluplus®.
- Analysis of classical methods (solvent evaporation, melting) and advanced techniques (pulse combustion drying, electrospinning, 3D printing).
- Evaluation of in vitro dissolution rates and in vivo bioavailability data.
Main Results:
- Kollidon® VA 64 and Soluplus® are effective polymeric carriers for enhancing solubility of poorly soluble drugs.
- Advanced manufacturing technologies offer improved methods for ASD production.
- Both polymers demonstrate potential in improving dissolution rates and bioavailability.
Conclusions:
- Kollidon® VA 64 and Soluplus® are valuable polymers for creating stable amorphous solid dispersions.
- Advanced manufacturing techniques can overcome traditional limitations in ASD production.
- These polymeric carriers facilitate enhanced solubility and bioavailability for poorly soluble active pharmaceutical ingredients.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
