alpha-Pyrrolidinovalerophenone (also known as α-PVP, A-PVP, alpha-PVP, and flakka) is a novel stimulant substance of the cathinone class. α-PVP is chemically related to prolintane and belongs to a group called the substituted cathinones, which includes compounds like MDPV, hexen, and a-PHP. It acts as a norepinephrine-dopamine reuptake inhibitor.
α-PVP was patented in the 1960s by Boehringer Ingelheim, although it was never marketed. Reports of its use began to appear in the early 2010s. α-PVP has been subject to much scrutiny by the media as one of the ingredients found in “bath salts” or “legal highs” products. It has been mass produced in China and sold online as a research chemical.
α-Pyrrolidinopentiophenone is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug.
