Povidone is widely used in pharmaceutical products, mainly in solid preparations. In tablets, povidone solution is used as a binder in wet-process granules.
Povidone powder can also be directly mixed into other powders in a dry state, and then added to water, alcohol or water alcohol solution for granulation.
In oral or non-gastrointestinal administration, POvidone acts as a solubilizer to accelerate the dissolution of insoluble drugs from solid preparations. Povidone solution can also be used as a coating material.
In addition, POvidone is used as a suspension aid, stabilizer, or viscosifier in some topical and oral suspensions and solutions. The solubility of many insoluble drugs increases when mixed with POvidone.
