What is vinyl pyrrolidone used for?
Polyvinylpyrrolidone (PVP) is a non-ionic synthetic polymer composed of repeating 1-vinyl-2-pyrrolidone monomers. Soluble forms of PVP, also known as povidone, are used extensively in the pharmaceutical industry largely as a binder in tablet manufacturing.
Is PVP a binder?
PVP or povidone is a hygroscopic, amorphous, synthetic polymer consisting of linear 1-vinyl-2-pyrrolidinone groups. As a binder, PVP is used in the concentration range of 0.5%–5% w/w. Different degrees of polymerization of PVP resulted in polymers of various molecular weights.
What does PVP mean in medical terms?
PVP. Peripheral Venous Pressure. Health, Healthcare, Diagnosis.
Is polyvinylpyrrolidone natural or synthetic?
Polyvinylpyrrolidone (PVP), also called as Povidone, is a synthetic polymer obtained by radical polymerization of the monomer, N-vinylpyrrolidone [1].
What does PPV stand for in medical terms?
positive predictive value
The likelihood that an individual with a positive test result truly has the particular gene and/or disease in question. Also called positive predictive value.
What does Rp stand for in medical terms?
Retinitis pigmentosa (RP) is a group of rare eye diseases that affect the retina (the light-sensitive layer of tissue in the back of the eye). RP makes cells in the retina break down slowly over time, causing vision loss. RP is a genetic disease that people are born with.
Is polyvinylpyrrolidone a drug?
Polyvinylpyrrolidone, also known as povidone or PVP, is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs.
Why does PPV mean?

What is polyvinylpyrrolidone PVP?
Polyvinylpyrrolidone (PVP) is a water-soluble polymer obtained by polymerization of monomer N-vinylpyrrolidone. PVP is an inert, non-toxic, temperature-resistant, pH-stable, biocompatible, biodegradable polymer that helps to encapsulate and cater both hydrophilic and lipophilic drugs.
How do you test for polyvinylpyrrolidone toxicity?
Skin prick tests were performed with povidone–iodine solution, polyvinylpyrrolidone, gentamicin sulfate, and two other medicines containing polyvinylpyrrolidone. The histamine release test was assessed using peripheral blood basophils. Skin prick tests with povidone–iodine, polyvinylpyrrolidone and the other medicines were all negative.
Is polyvinyl pyrrolidone a plasma expander?
Ravin H.A., Seligman A.M., Fine J. Polyvinyl pyrrolidone as a plasma expander; studies on its excretion, distribution and metabolism. N. Engl. J. Med. 1952;247:921–929. doi: 10.1056/NEJM195212112472403. [PubMed] [CrossRef] [Google Scholar] 56.
What is PVPP in hair gel?
PVP is the basis of the early formulas for hair sprays and hair gels, and still continues to be a component of some. As a food additive, PVP is a stabilizer and has E number E1201. PVPP (crospovidone) is E1202.
