Summary

The case study demonstrates the effectiveness of PolyStardone® as a super disintegrant for a tablet matrix containing both water-soluble (lactose) and insoluble (dibasic calcium phosphate), mediumcompactable fillers. The performance of PolyStardone® was compared to other crospovidone products in the market. We believe that: PolyStardone® XL and PolyStardone® XL-10 have similar performance to import competitor A and import B, and are better than domestic competitor C and D in terms of compactibility and disintegration capabilities. In this case, PolyStardone® XL ensures rapid disintegration regardless of compaction force. Furthermore, PolyStardone® XL-10 offers additional benefits in increasing tablet tensile strength without a compromise in its disintegration efficiency.

Features

Physical Properties : Non-ionic polymer High porosity and hydration Easy compression and viscoelastic deformation No gel formation Stable in acids and bases; Performance Impact :; No interaction with ionic APIs (i.e. Ranitidine, Cetirizine) Combines wicking and swelling mechanisms to achieve rapid tablet disintegration at low concentrations(1-5%) Increased tablet tensile strength and reduced friability due to high compressibility. Especially suitable for poorly compressible APIs No gel formation even at higher concentrations (10%), idea for ODTs Suitable for a variety of pH sensitive formulations

Appearance

White or yellowish-white powder

Application

Insoluble in water or common organic solvents, the powder particles are porous microstructures with high specific surface area.. As a super disintegretant, it will not form gel and can effectively improve the disintegration time.
