NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing pharmaceutical science through high-quality chemical compounds. Among these, Polyvinylpyrrolidone (PVP), particularly the high-grade K90 variant, stands out for its indispensable role in modern drug formulation. This non-ionic polymer, synthesized from N-vinylpyrrolidone, offers a unique combination of properties that make it a cornerstone excipient for a wide array of pharmaceutical applications.

One of the most significant contributions of PVP K90 to the pharmaceutical industry is its efficacy as a dissolution enhancer. Many active pharmaceutical ingredients (APIs) exhibit poor water solubility, which can severely limit their bioavailability and therapeutic effectiveness. PVP K90, with its strong complexing ability, can form amorphous solid dispersions with these poorly soluble drugs, thereby significantly increasing their dissolution rate and absorption. This capability is crucial for developing oral dosage forms that deliver consistent and predictable therapeutic outcomes.

Furthermore, PVP K90 is widely recognized for its excellent performance as a tablet binder. In the production of tablets, binders are essential for holding the active ingredients and excipients together, ensuring the tablet's mechanical strength and preventing its disintegration during manufacturing, packaging, and transport. The binding properties of PVP K90 allow for the formation of robust granules during wet granulation processes and contribute to the overall integrity of the final tablet product.

Beyond its binding capabilities, PVP K90 also functions effectively as a suspending agent and disintegrant. As a suspending agent, it helps to keep insoluble drug particles uniformly dispersed in liquid formulations, preventing them from settling out and ensuring accurate dosing. When used as a disintegrant, it aids in the rapid breakdown of tablets once they come into contact with physiological fluids, facilitating the release of the active ingredient for absorption. This multi-faceted functionality underscores the versatility of PVP K90.

The application of PVP extends beyond oral solid dosage forms. Its ability to form complexes with iodine has led to the development of povidone-iodine, a broad-spectrum antiseptic and disinfectant widely used in medical settings for wound care and surgical preparation. This highlights the biocompatibility and broad utility of PVP-based compounds. Moreover, PVP is increasingly utilized in the formulation of contact lenses, where it acts as a lubricant and wetting agent, improving wearer comfort.
