Plasdone™ S-630 copovidone

Plasdone™ S-630 copovidone is 60:40 copolymer of N-vinyl-2-pyrrolidone and vinylacetate. The vinyl acetate in the polymer backbone lowers the polymer’s glass transition temperature compared with polyvinylpyrollidone (PVP) homopolymers and reduces hygroscopicity. It acts as an excellent tablet binder in dry granulation and direct compression tablet process. It is highly compressible and produces more flexible, less brittle films compared to films of PVP homopolymers. Its lower hygroscopicity improves stability in high humidity. It improves solubility and bioavailability of poorly soluble drug actives through formation of solid dispersions. Plasdone™ S-630 copovidone forms tough, clear, flexible films with high substantivity.
