Applications

 

KoVidone® VA64 possesses excellent powder and film properties for broad application in the pharmaceutical field:

 

·       Water soluble tablet binder; suitable for wet or dry granulation and direct compression processes, improves particle compressibility.

·       Film-former; permeable film coating for tablet and sugar coatings to protect against splitting, decrease moisture sensitivity and provide good film adhesiveness, elasticity, and hardness.

·       Porogenic agent; for use in taste-masking and component of the matrix material used in controlled-release formulation.

·       Solubilizing agents; for solid dispersion processes to enhancing bioavailability and improve drug solubility. For use in both Hot Melt Extrusion and Spray Solvent Drying

 

The addition of KoVidone® VA64 to HPMC film coating solutions can effectively reduce the viscosity of the HPMC solution while enhancing resultant film characteristics by improving film formation, flexibility and gloss.

 

Nimodipine- KoVidone® VA64 solid dispersion HME process

Due to its lower glass transition temperature Tg, KoVidone® VA64 is especially suited for developing solid dispersion drug systems via hot melt extrusion processing.

 

Hot melt extrusion (HME) technology is a new technique to prepare pharmaceutical dosage forms. HME shows unique advantages and is used to: improve the dissolution rate of extremely poorly soluble drugs..

 

HME uses no solvent in the production process, the drug is hot melt extruded with a suitable polymer carrier (Kovidone® VA64). The extrusion process converts crystalline drugs to their amorphous form (Solid Dispersion) that helps to improve both drug solubility and bioavailability and increase the stability of the finished dosage form.

 

Solid Dispersions can also be produced via Spray Solvent Drying whereby the Kovidone and poory soluble active are dissolved in a suitable solvent and spray dried. The resulting Solid Dispersion is similar to that achieved with HME.
