Swapnroop Pharma manufactures and supplies Polyvinylpyrrolidone-Vinyl Acetate Copolymer (PVP/VA), a synthetic polymer used as a functional pharmaceutical excipient in solid oral and other formulation systems.
Polyvinylpyrrolidone-Vinyl Acetate Copolymer is a copolymer consisting of N-vinyl-2-pyrrolidone and vinyl acetate units. It combines properties associated with polyvinylpyrrolidone and vinyl acetate, providing useful binding, film-forming, solubilizing and stabilization characteristics.
PVP/VA is particularly useful in pharmaceutical formulations where a polymeric excipient is required to improve powder binding, film formation or the performance of poorly water-soluble ingredients.
PVP/VA is available in different grades and polymer compositions. A commonly used pharmaceutical grade is Povidone-Vinyl Acetate, including grades such as PVP/VA 64, where the approximate ratio of vinylpyrrolidone to vinyl acetate is reflected in the grade designation.
The physicochemical properties of the material depend on its polymer composition, molecular weight and grade. Therefore, the exact grade should be selected according to the intended pharmaceutical application.
Polyvinylpyrrolidone-Vinyl Acetate Copolymer can be used as:
