Product Description
Crospovidone, also known as cross-linked polyvinylpyrrolidone (PVP), is a synthetic polymer. It is a white to off-white, free-flowing, hygroscopic powder with a slight characteristic odor. Crospovidone is insoluble in water, acids, and organic solvents but swells rapidly when dispersed in water.
Function
Crospovidone functions primarily as a superdisintegrant in pharmaceutical formulations. It enhances the dissolution of active pharmaceutical ingredients (APIs) by breaking down tablets into smaller fragments, which increases the surface area exposed to bodily fluids and speeds up drug release and absorption.
Application
- Pharmaceutical Tablets and Capsules: As a superdisintegrant, it is used in various types of tablets and capsules to ensure rapid disintegration and improve bioavailability.
- Orally Disintegrating Tablets (ODTs): Enhances the rapid breakdown of tablets upon contact with saliva, making it suitable for patients with difficulty swallowing.
- Direct Compression Formulations: Facilitates the direct compression of tablets, simplifying the manufacturing process.
- Wet Granulation Processes: Acts as a binder and improves the mechanical strength of granules.
- Stabilization of Suspensions: Prevents the settling of suspended particles, improving the stability of liquid dosage forms.
