What is the difference between PVP K30 and PVP K90?
K-value indicates molecular weight and viscosity. PVP K30 (K value 27–33) is a low-to-medium molecular weight grade used as a binder in granulation and a dissolution enhancer. PVP K90 (K value 88–96) is a high molecular weight grade used for sustained-release matrices and as a film former. K30 is the most commonly used grade in tablet manufacturing.
What is the recommended use level of PVP K30 as a tablet binder?
In wet granulation, PVP K30 is typically used at 2–5% w/w of the granulation mass dissolved in water or IPA as a binder solution. In dry granulation or direct compression, it is used at 0.5–5% as a dry binder.
Can PVP K30 improve dissolution of poorly soluble drugs?
Yes. PVP K30 is an effective solid dispersion carrier and dissolution enhancer for BCS Class II drugs. When co-processed with a poorly soluble API via spray drying or hot melt extrusion, PVP K30 inhibits API recrystallisation and maintains amorphous drug in solution.
