Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
Povidone-iodine is a chemical complex of the polymer povidone (polyvinylpyrrolidone, PVP) and triiodide (I − 3). [24] It is synthesized by mixing the PVP polymer with iodine (I 2), allowing the two to react. [25] It is soluble in cold and mild-warm water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol.
Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, PVPP, crospovidone, crospolividone, or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP).. The cross-linked form of PVP is used as a disintegrant (see also excipients) in pharmaceutical tablets. [1]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
α-Pyrrolidinopentiophenone (α-PVP), also known as α-pyrrolidinovalerophenone, O-2387, β-keto-prolintane, prolintanone, [2] [3] or desmethylpyrovalerone, is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug and often consumed for recreational reasons.
Russell's viper, Daboia russelii Dilute Russell's viper venom time (dRVVT) is a laboratory test often used for detection of lupus anticoagulant (LA). It is an assessment of the time for blood to clot in the presence of a diluted amount of venom from Russell's viper (Daboia russelii), a highly venomous snake native to the Indian subcontinent and named after the herpetologist Patrick Russell.
Guanfacine, sold under the brand name Tenex (immediate-release) and Intuniv (extended-release) among others, is an oral alpha-2a agonist medication used to treat attention deficit hyperactivity disorder (ADHD) and high blood pressure.
TH-PVP is a substituted cathinone derivative which has been sold as a designer drug. It was first identified by a forensic laboratory in Hungary in 2015, [ 2 ] but has subsequently been found in numerous other countries around the world including Spain, Belgium, Poland, Turkey and Brazil.
