Copovidone VA64 (Kollidon VA64)

CAS Number: 25086-89-9

Copovidone VA64 is a copolymer of vinylpyrrolidone and vinyl acetate in a 6:4 ratio, known commercially as Kollidon VA64. It combines the excellent binding properties of PVP with the plasticizing effect of PVA, making it ideal for hot melt extrusion (HME) and spray-drying applications for amorphous solid dispersion formation. It is widely used to enhance bioavailability of BCS II and IV drugs.
