Application

Polyvinylpyrrolidone K 90 Average Molecular Wt. 360000 serves as a versatile excipient primarily utilized in the pharmaceutical industry for its binding and solubilizing properties. Characterized by its hygroscopic nature and manufactured in plate form through drum drying, this povidone variant excels in enhancing the solubility and dissolution rates of poorly soluble drugs in solid-dosage forms. It is commonly incorporated into formulations as a binder during wet-granulation processes and can also be granulated in situ using water, alcohol, or hydroalcoholic solutions. Beyond its binding capabilities, Polyvinylpyrrolidone K 90 also functions as a suspending, stabilizing, or viscosity-increasing agent, making it suitable for a range of topical and oral suspensions and solutions. Additionally, it is used in the formulation of oral and parenteral solutions, with special pyrogen-free grades available for parenteral applications.
