What Is The Role Of Copovidone

- Jul 04, 2020-


Because the copovidone molecule is a copolymer structure of NVP and VA, it has both the properties of PVP and PVAC. Comparing the properties of the above three products, copovidone retains the good water solubility, adhesion and film forming properties of PVP, and has relatively lower water absorption, wider solubility and better plasticity than PVP. And stronger surface activity (Note: The affinity for vegetable water surface is greater than PVP). Therefore, this product is an excellent tablet binder, and the tablets made by it have the characteristics of high hardness and low friability, and the tablet can be less bonded under humid conditions, especially suitable for high doses , Poor water party sex and the production and granulation of water-sensitive drugs.
