para-Fluorophenylpiperazine (pFPP,4-FPP,4-Fluorophenylpiperazine;Fluoperazine,Flipiperazine) is apiperazine derivative with mildlypsychedelic andeuphoriant effects.[2][3] It has been sold as an ingredient in legalrecreational drugs known as "Party pills", initially inNew Zealand and subsequently in other countries around the world.[4]

pFPP has been foundin vitro to act mainly as a5-HT1A receptoragonist, with some additional affinity for the5-HT2A and5-HT2C receptors. It has also been shown toinhibit thereuptake ofserotonin andnorepinephrine, and to possibly induce theirrelease.

pFPP was originally discovered as ametabolite of the hypnotic5-HT2A andα1-adrenergic receptorantagonistniaprazine in 1982,[5] but was rediscovered in 2003 as a potential recreational drug, and sold as an ingredient in "Party pills" in New Zealand, under brand names such as "The Big Grin", "Mashed", and "Extreme Beans". Subsequently it has continued to be used as an ingredient in black market "ecstasy" pills around the world.[6]

pFPP has little stimulant effects, with its subjective effects derived mainly from its action as a 5-HT1A receptor agonist.[7] pFPP is active at doses between 20 and 150 mg, but higher doses cause a range of side-effects such asmigraineheadaches,muscle aches,anxiety,nausea, andvomiting. Metabolic studies have shown pFPP to be an inhibitor of variousCytochrome P450 enzymes in the liver which may contribute to its side-effect profile.[8]

Based on the recommendation of the EACD, the New Zealand government has passed legislation which placed BZP, along with a number of other piperazine derivatives, into Class C of the New Zealand Misuse of Drugs Act 1975. A ban was intended to come into effect in New Zealand on December 18, 2007, but the law change did not go through until the following year, and the sale of BZP and the other listed piperazines became illegal in New Zealand as of 1 April 2008. An amnesty for possession and usage of these drugs remained until October 2008, at which point they became completely illegal.[9] This drug has been detected in a drug-facilitated sexual assault case in the United States of America.[citation needed]
