What is the current formulation and excipient profile of ultramicrosize griseofulvin?
Ultramicrosize griseofulvin is a formulation designed to enhance solubility and bioavailability of the active pharmaceutical ingredient (API). The key features include:
- Particle Size Reduction: Particles are reduced to nanometer scale, typically below 100 nanometers.
- Primary excipients: Cyclodextrins (e.g., hydroxypropyl-beta-cyclodextrin) are often used as solubilizing agents.
- Additional excipients: Corn starch, magnesium stearate, and various disintegrants.
The formulation aims to improve dissolution rate compared to conventional griseofulvin, which has poor water solubility.
Which excipient strategies improve solubility and stability?
Strategies include:
- Use of cyclodextrin complexes to enhance solubility.
- Incorporation of wetting agents such as polysorbates.
- Use of pore-forming excipients (e.g., mannitol) for amorphous dispersions.
- Stabilizers like antioxidants (e.g., ascorbyl palmitate) to prevent degradation.
Cyclodextrins form inclusion complexes with griseofulvin, increasing aqueous solubility significantly. Cyclodextrin complexes are approved excipients with established safety profiles.
What are the commercial opportunities related to excipient innovations?
