PVP K series possess excellent binding, film-forming, dispersing and thickening properties and are widely used in the following dosage forms:

 

Binder: suitable for wet and dry granulation and direct compression in tableting, improves particle compressibility and can be added to powder blends in dry or granulated forms by the addition of water, alcohol or hydro-alcoholic solutions.  PVP K series, its dosage with the mechanical strength of the drug tablet and the nature of the drug itself, and is generally 0.5% to 5%.

 

Solubilizer: suitable for oral and parenteral formulations, enhancing the solubility of poorly soluble drugs in solid dispersion forms.

 

Coating agent or binder: coating of active pharmaceutical ingredients on a support structure.

 

Suspending, stabilizing or viscosity-modifying agent: suitable for topical and oral suspension and solution applications. The solubility of poorly soluble drugs may be enhanced by combining with PVP K series.
