At NINGBO INNO PHARMCHEM CO.,LTD., we believe in empowering our partners with comprehensive knowledge about the materials they use. Today, we focus on Povidone K90, a cornerstone pharmaceutical excipient, exploring the science that underpins its critical functions.

Povidone K90, chemically known as Polyvinylpyrrolidone or PVP K90, is a water-soluble polymer synthesized from N-vinylpyrrolidone. Its K-value, indicating its average molecular weight and viscosity, is crucial. The '90' signifies a higher molecular weight compared to other grades, imparting unique properties essential for pharmaceutical applications. This understanding is key for those searching for specific grades like PVP K90 dissolving assistant.

As a tablet binder, Povidone K90 creates strong, coherent tablets. Its molecular structure allows it to form hydrogen bonds and van der Waals forces with drug particles and other excipients, effectively holding them together. This ensures that tablets maintain their shape and do not crumble during handling or transport, a vital aspect of PVP K90 quality and safety.

The role of Povidone K90 as a solubilizer is equally significant. For many active pharmaceutical ingredients (APIs) that exhibit poor aqueous solubility, Povidone K90 can form complexes through molecular encapsulation or solid dispersions. This process enhances the dissolution rate and, consequently, the bioavailability of the drug, meaning more of the active ingredient is absorbed into the bloodstream. This makes it indispensable for developing effective oral drug formulations.

Beyond binding and solubilizing, Povidone K90 also functions as a stabilizer and suspending agent in liquid preparations. It helps maintain the homogeneity of suspensions and prevents the degradation of sensitive drugs, thereby extending shelf-life and ensuring consistent product quality. The reliability of Povidone K90 pharmaceutical excipient is thus a key factor in drug formulation success.

NINGBO INNO PHARMCHEM CO.,LTD. provides Povidone K90 that adheres to the highest standards, ensuring its efficacy and safety in pharmaceutical manufacturing. Our commitment to quality supports the innovation and reliability that the pharmaceutical industry demands.
