This class of NPS mediates stimulant effects by promoting an action in dopaminergic, noradrenergic, and predominantly serotoninergic neurotransmission. The toxicity is characterized by symptoms including insomnia, headaches, nausea, anxiety, depression, paranoia, and auditory hallucinations. Over the last decade, New Zealand has led the world in the legal sale and uncontrolled use of the recreational drug benzylpiperazine (BZP), the active ingredient of ‘party pills’. One survey found that 40% of 18Á29-year-olds admitted to using BZP-based party pills while, in another study, 44% of first-year university students had used the drug.

The use of piperazine derivatives, colloquially named ‘party pills’, has been escalating in New Zealand and worldwide since their introduction in the 1990s. Benzylpiperazine (BZP) is often used alone, or can be combined with trifluoromethylphenylpiperazine (TFMPP). Taken together as an oral dose, they have been reported to produce effects similar to 3, 4-methylenedioxymethamphetamine (MDMA). While the pharmacokinetic data have recently been published, little research has been conducted on the subjective effects of these piperazines on humans. This paper outlines the subjective effects observed following oral doses of BZP (200 mg) and TFMPP (60 mg) alone, or in combination (100/30 mg) compared to placebo. BZP showed significant dexamphetamine-like stimulant effects, inducing euphoria, sociability, and drug liking, whereas TFMPP induced fewer stimulant-like effects and increased anxiety, via its serotonergic effects.

Medical Use
The results were used to calculate the coefficients of variation in retention times and peak areas. 1-benzylpiperazine (commonly known as BZP), 1-(3-trifluoromethylphenyl)piperazine (commonly known as TFMPP) were listed as Class A controlled drugs in the First Schedule of the Misuse of Drugs Act on 15 November 2010. Mcpp – interacts with a wider array of receptors and transmitters, mainly serotonin, adrenaline and dopamine. This is why the euphoric and hallucinogenic effects are seen to be similar to MDMA.
- Together with the other signatories, we are committed to prevent the misuse and illicit trafficking of these drugs, whichinclude cannabis.
- The benefit of the LC-MS method is the high sensitivity of determinations, while the LC-DAD method ensures high reproducibility of results.
- Some studies have even shown that at higher doses of both drugs, a greater level of dopamine is produced than the drug on its own 1.
- An exemplar chromatogram of the tested piperazine derivatives is shown in Figure 1 (intensity versus retention time).
Derivatives

There are several routes to the synthesis of mCPP, the most common of which is the reaction of diethanolamine with m-chloroaniline. Other methods involve the reaction of m-chloroaniline with bis(2-chloroethyl)amine or the reaction of piperazine with m-dichlorobenzene. The other two isomers of CPP could be made in a similar way.It is unlikely that the mCPP found in illicit products has been synthesised in clandestine laboratories since it is available commercially as the base or as the hydrochloride salt.
1 LC-MS Method—MRM Transitions And Chromatographic Separation
Management strategies are often limited to supportive and symptomatic care due to the limited published data on alternative treatment approaches. The purpose of this article is to offer health care providers, emergency medical personnel in particular, an awareness and understanding of the dangers related to some of the new psychoactive drugs of abuse. BZP is banned in several countries, including the USA, Republic of Ireland, Australia and New Zealand, but is available on a more or less restricted basis in many jurisdictions. A range of other piperazine derivatives have also been sold as ingredients in party pills, and many of these branded “proprietary blends” have subsequently been sold in countries around the world.
Legal Status TFMPP
The presented methods enable the detection of piperazine designer drugs in a different concentration range and additionally in a short time of analysis. Rapid analytical confirmation of the cause of poisoning is essential in medical interventions that save human health and life. The proposed methods may be useful techniques in situations requiring analytical confirmation of piperazine designer drug poisoning and may be helpful in comprehensive toxicological diagnostics. The available literature and data indicate an increasing number and chemical diversity of new psychoactive substances (NPS), also known as designer drugs 1,2,3. Products of this type are advertised as a modern alternative to illegal drugs, the possession and sale of which is prohibited by law 4,5.
8 LC-DAD Analysis—Validation Of The Method
They were mostly used for their stimulant properties and to enhance socialisation, and were often taken in combination with other legal and illicit drugs. Young people had suffered a range of physical and emotional negative effects, although none of these was reported as being life-threatening or long-term. Many participants had reduced the frequency with which they used BZP-party pills due to adverse effects.
Overdose And Toxicity Of Piperazines
- UV-VIS spectra, retention times and compliance with the standard were obtained for all tested compounds.
- The present microdialysis findings with TFMPP show that this drug causes elevations in extracellular 5-HT in vivo, consistent with the in vitro findings (see Figure 8).
- Nonetheless, several factors argue against the hypothesis of 5-HT facilitation of DA release with regard to the effects of BZP/TFMPP.
- In this study, the metabolic activities of three major hepatic CYP isoforms (2C19, 2D6, and 3A4) were investigated on structurally different central nervous system (CNS) acting drugs, amitriptyline, fluphenazine, and dothiepin.
- Potentially risky behaviours identified included taking large doses, mixing BZP-party pills with alcohol and other substances, and driving whilst under the influence of BZP-party pills.
- The methods presented in the article may complement each other for the research on piperazines or they may be used independently.
The mixture is made to try and mimic the effects of MDMA, where TFMPP is meant to reproduce the psychedelic effects of MDMA, and BZP the euphoric effects. It is a class of intravenous anesthetics and is commonly used to induce and maintain anesthesia during surgery and other medical procedures requiring sedation. Etomidate produces a sedative, hypnotic and relaxing effect by acting on the central nervous system and may therefore be addictive. Etomidate is commonly mixed into e-cigarettes oils and sold illegally as e-cigarettes or disposable e-cigarettes. BZP has no current human or veterinary pharmaceutical use in any country. Although piperazine itself is used as an anthelminthic drug, neither BZP nor any other piperazine derivative is licensed for this purpose.
As mentioned previously, activation of 5-HT2A receptors by endogenous 5-HT contributes to MDMA-induced increases in extracellular DA (Schmidt et al, 1994; Gudelsky and Nash, 1996). Furthermore, perfusion of 5-HT directly into the rat striatum or nucleus accumbens evokes marked elevations in extracellular DA (Benloucif and Galloway, 1991; Parsons and Justice, 1993). Nonetheless, several factors argue against the hypothesis of 5-HT facilitation of DA release with regard to the effects of BZP/TFMPP. First, as shown in Table 1, high-dose BZP/TFMPP produced a smaller rise in dialysate 5-HT (872%) when compared to high-dose MDMA (1445%), yet BZP/TFMPP increased extracellular DA levels about four-fold more than MDMA.

The methods presented in the article may complement each other for the research on piperazines or they may be used independently. The appropriate chromatographic column was selected and the chromatographic conditions were optimized. The chromatography has been optimized with an eluent gradient, obtaining a good peak shape and good separation of analytes. UV-VIS spectra, retention times and compliance with the standard were obtained for all tested compounds. Characteristic UV-VIS spectra of piperazine and pentedrone derivatives are shown in Figure 3.
In contrast to previous research, we found a strong displacement effect following criminalisation with half of the sample increasing their use of other illegal drugs and, for a third, their use of alcohol. Such studies allow to predicting possible drug-drug interactions that might occur during co-administration of studied compounds with other drugs that are metabolized by an identified enzyme. The compounds were incubated in vitro together with the isolated CYP isoforms. After the incubation, samples were analyzed by liquid chromatography coupled with mass spectrometry. The results showed the main contribution of CYP3A4 isoform in biotransformation of the investigated derivatives.
In 1999, drug researchers in Japan found that a particular form of benzylpiperazine stimulates a brain chemical called acetylcholine. This led to the discovery of donepezil (Aricept), which helps ward off memory loss in patients with Alzheimer’s and other brain diseases. TFMPP is controlled in Texas under Penalty Group 2, as a hallucinogenic substance. Since 2012, TFMPP has been listed as a Schedule III controlled substance in Canada,18 making possession of TFMPP a federal offence.
