Polyvinylpyrrolidone (PVP) Polyvinylpyrrolidone (PVP), also known as povidone, is a water-soluble polymer derived from the monomer N-vinylpyrrolidone. It is widely used in various industries due to its versatile properties. PVP is a synthetic polymer that is biodegradable, non-toxic, and biocompatible. It is recognized as safe by the Food and Drug Administration (FDA) and has excellent solubility in solvents of different polarities. Chemical Formular: (C6H9NO)n Uses of Polyvinylpyrrolidone (PVP) In the Pharmaceutical Industry: PVP is used as a synthetic polymer vehicle for dispersing and suspending drugs. It serves as a binder for tablets and capsules, a film former for ophthalmic solutions, and an adhesive for transdermal systems. It aids in flavoring liquids and chewable tablets and has been widely employed as a carrier in the pharmaceutical, biomedical, and nutraceutical fields for delivering different active principles. In Medical Procedures: In in-vitro fertilization laboratories, PVP is used to slow down spermatozoa in order to capture them for procedures like intracytoplasmic sperm injection (ICSI). Other Uses: PVP is also used as a cosmetics thickener and blood compatibilizer. In addition to these applications, PVP has been utilized in various other fields due to its inert, non-toxic, temperature-resistant, and pH-stable nature, making it suitable for encapsulating and catering to both hydrophilic and lipophilic drugs.
