Copovidone
Copovidone VA64 is a critical pharmaceutical excipient, known for its excellent binding capabilities, film-forming properties, and utility in controlled release formulations. It is a copolymer of N-vinylpyrrolidone and vinyl acetate, offering enhanced plasticity and lower hygroscopicity compared to Povidone.
- As a copovidone binder, it ensures tablets have good hardness and remain intact during processing.
- The film-forming agent properties of copovidone protect drugs from environmental factors like moisture and light, improving stability.
- Its role in sustained-release formulations is crucial, managing the gradual release of active ingredients.
- Utilizing copovidone CAS 25086-89-9 can simplify drug preparation processes and potentially reduce manufacturing costs.
