They can be used as dissolve-enhancing agents for some effective components in oral and external medicine. PVP K-25 and K-30 can also form complexs with a lot of insoluble effective components and help them to dissolve immediately to increase their bioavalability. It also can be used as suspanding stabilizer of some effective components such as sulfa and antibiotic, increase the contact time of eyedrops and eyes, improve the lubricating effect, reduce the irritation of medicines. It can prevent tablet coating from cracking and make pigments disperse evenly when used for tablet coating.
