As an excipient, PVP K90 is mainly used as a tablet binder, the dose used is less than 2% in terms of tablet weight because of better binding ability. Used as suspending stabilizer, pvp k90 can stabilize all kinds of effective components in medicines. And also pvp k90 can be used as viscosity-enhancing agent and film-forming agent for some oral liquids, effectiveness-prolonging agent and controlled-release agent for medicines.
