In the highly regulated and demanding pharmaceutical industry, the selection of excipients is paramount to the success of any drug product. Among the myriad of available materials, Polyvinylpyrrolidone (PVP) K90 stands out as a remarkably versatile and indispensable polymer. As a leading supplier of pharmaceutical-grade excipients, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical importance of high-quality ingredients like PVP K90 for optimal drug formulation and patient outcomes. This article delves into the multifaceted applications and benefits of PVP K90, highlighting why it remains a preferred choice for pharmaceutical manufacturers globally.

What is Polyvinylpyrrolidone (PVP) K90?

Polyvinylpyrrolidone, commonly known as PVP, is a water-soluble synthetic polymer derived from N-vinylpyrrolidone. The 'K' in PVP K90 refers to its Fikentscher K value, a measure of its viscosity and molecular weight. PVP K90, with its high molecular weight (typically around 360,000), exhibits exceptional binding, film-forming, dispersing, and stabilizing properties. It is supplied as a white or off-white powder, characterized by its hygroscopic nature and excellent solubility in water and many organic solvents.

Key Roles of PVP K90 in Pharmaceutical Formulations:

The unique physicochemical properties of PVP K90 make it a valuable excipient in a wide array of pharmaceutical dosage forms. Its primary functions include:

  • Binder: PVP K90 is an excellent binder for tablet and granule formulations, whether produced by wet granulation, dry granulation, or direct compression. It improves the compressibility of powders and ensures the mechanical strength and integrity of tablets, making them resistant to disintegration during handling and transport. Manufacturers looking to buy PVP K90 in bulk for tablet manufacturing will find its binding efficacy crucial.
  • Solubilizer and Bioavailability Enhancer: For poorly soluble active pharmaceutical ingredients (APIs), PVP K90 acts as a solubilizing agent. By forming amorphous solid dispersions with APIs, it can significantly enhance their dissolution rate and bioavailability, leading to improved therapeutic efficacy. This is a critical consideration for formulators seeking to optimize drug absorption.
  • Dispersing Agent: PVP K90 is highly effective in dispersing pigments and APIs in liquid preparations, ensuring uniform distribution and preventing sedimentation. This is vital for the consistent delivery of medications in suspensions and oral solutions.
  • Stabilizer: It serves as a stabilizer for enzymes and heat-sensitive drugs, protecting them from degradation and maintaining their activity over time. This is particularly important for biopharmaceutical products and specialized formulations.
  • Film-Forming Agent: PVP K90 forms clear, hard, and glossy films, making it ideal for film coating of tablets and capsules. These coatings can protect the drug from environmental factors, mask unpleasant tastes, and control drug release.
