NINGBO INNO PHARMCHEM CO.,LTD. recognizes the profound impact that high-quality excipients have on the efficacy and safety of pharmaceutical products. Among these essential components, Povidone K90 (PVP K90) stands out for its remarkable versatility and indispensable role in modern drug formulation. As a water-soluble polymer derived from N-vinylpyrrolidone, PVP K90, identified by its CAS number 9003-39-8, has become a cornerstone in the development of a wide array of dosage forms.

One of the primary functions of PVP K90 in the pharmaceutical industry is its exceptional performance as a tablet binder. Its strong adhesive properties, even at low concentrations, ensure the formation of robust and uniform tablets, whether manufactured through wet granulation, dry granulation, or direct compression. This characteristic is crucial for maintaining the physical integrity of tablets during manufacturing, packaging, and patient use, directly impacting the patient's experience and the drug's therapeutic outcome. The ability of PVP K90 to create hard, non-friable tablets with excellent binding capacity is a significant advantage for formulators aiming for high-quality products.

Beyond its binding capabilities, Povidone K90 is highly valued for its role as a solubilizer and dissolution enhancer. Many active pharmaceutical ingredients (APIs) exhibit poor water solubility, which can limit their absorption and bioavailability. PVP K90 effectively addresses this challenge by forming solid dispersions or complexes with these APIs, thereby increasing their dissolution rate and improving their absorption in the body. This application is particularly important for oral formulations where efficient drug release is paramount for achieving the desired therapeutic effect. The use of PVP K90 as a solubilizer directly contributes to enhancing drug efficacy and patient compliance.

Furthermore, PVP K90 serves as a crucial stabilizer in various pharmaceutical preparations, including oral suspensions and topical formulations. Its ability to prevent degradation caused by oxidation or light, and to stabilize suspensions and emulsions, ensures the prolonged efficacy and safety of the medication. This stabilizing effect is vital for maintaining the chemical integrity of the API throughout the product's shelf life. The consistent quality and predictable behavior of PVP K90 make it a reliable choice for formulators seeking to optimize their product's stability profile.

The broad applicability of PVP K90 extends to its use as a disintegrant, a film-forming agent for ophthalmic solutions, a glidant for capsules, and a dispersant for liquid medications and colorants. Its comprehensive profile as a pharmaceutical excipient underscores its importance in creating effective, stable, and user-friendly drug products. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying high-purity PVP K90 that meets stringent quality standards, ensuring that pharmaceutical manufacturers have access to this vital ingredient to advance their drug development and production goals.
