Human subjects report that MDMA induces a pleasurable mix of stimulant-like and hallucinogen-like effects, coupled with feelings of increased emotional sensitivity and closeness to others (Vollenweider et al, 1998). The neurobiological mechanisms underlying psychoactive effects of MDMA seem to involve the release of 5-HT, and possibly DA, from nerve cells in the brain (Liechti and Vollenweider, 2001). At the molecular level, MDMA serves as a substrate for 5-HT transporters (SERTs) and DA transporters (DATs), thereby triggering nonexocytotic release of transmitter molecules from 5-HT and DA neurons (Green et al, 2003). BZP itself was initially developed as a potential antidepressant drug, but was found to have similar properties to amphetamine and therefore liable to abuse.
- In addition, it increases the level of DA and NA, which leads to effects similar to those of amphetamine 27.
- During the overnight acclimation period and during microdialysis sampling, each rat was housed within a Plexiglass arena (40 cm length, width and height) that was equipped with an automated activity monitoring system (Tru Scan, Coulbourn Instruments).

- However, other studies using GC-MS, LC-MS and LC-DAD usually did not deal directly with the piperazine designer drugs 12,15,69,75,76.
- The drug acts by paralyzing the muscles of mature worms and dislodging them from the walls of the intestines.
Mixing With Other Drugs
Like ecstasy, piperazine has spread from the club scene to high schools and college campuses. Whilst it has been linked to a number of fatalities in association with BZP, there are no documented cases of it being toxic in its own right 1. If you or someone else needs urgent help after taking drugs or drinking, call 999 for an ambulance. (2008), ‘Investigation of the first deaths in the United Kingdom involving the detection and quantitation of the piperazines BZP and 3-TFMPP, Journal of Analytical Toxicology, Volume 32, No 2, pp. 172–177. Piperazines are usually available in the form of pills (regularly pressed with logos similar to ecstasy pills), capsules or loose powders, and are mainly consumed by ingestion.
1 LC-MS Method
Muscle stiffness, uncontrollable shaking, jaw clenching, and nervous tics may occur in users. Piperazines have been found to act as stimulants as a result of dopaminergic, noradrenergic, and predominantly serotoninergic effects produced in the brain. The majority of pharmacological studies of piperazines have focused on BZP and have indicated that it produces toxic effects similar to amphetamine and other sympathomimetics. According to animal studies, its effects are less potent than amphetamine, methamphetamine and MDMA 10. TFMPP, used in conjunction with BZP, has been reported to produce some of the effects of MDMA, but with a lower potency 11, while mCPP has been indicated to produce similar stimulant and hallucinogenic effects as MDMA 12. The presented methods enable the detection of piperazine designer drugs in a different concentration range and additionally in a short time of analysis.
As an agonist at the 5HT2C receptor, and an antagonist at the 5HT2B receptor, mCPP has been widely used as a probe of serotonin function in psychiatric research. An industrial use of mCPP is as an intermediate in the production of trazodone and three related substances.Trazodone is licensed in a number of Member States for the treatment of depression and other disorders. The substance 1-(3-chlorophenyl)-4-(3-chloropropyl)-piperazine (mCPCPP) is a precursor used in the manufacture of antidepressant drug nefazodone. Misuse of the illicit drug, 3,4-methylenedioxymethamphetamine (MDMA, or ‘Ecstasy’), is increasing worldwide, especially among children and young adults (Landry, 2002). The allure of MDMA is likely related to its unique profile of psychotropic actions.
Thus, it appears that interactions of BZP and TFMPP with monoamine transporters cannot explain synergistic effects of the combination, and any number of mechanisms may underlie the apparent drug–drug synergism. One possibility is that large elevations in extracellular 5-HT produced by BZP/TFMPP might lead to facilitation of DA transmission (see Kuroki et al, 2003; Yamamoto et al, 1995). 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).
Their hallucinogenic properties are the result of interaction with the 5-HT2A receptor, which may additionally lead to changes in the functioning of sensory processes 4,23. High doses of BZP when bound to the 5-HT2 receptor, produce an effect approximately 10 times weaker than that of MDMA 24,25,26. In addition, it increases the level of DA and NA, which leads to effects similar to those of amphetamine 27. The simultaneous use of BZP with TFMPP or mCPP mimics the ecstasy profile, i.e., the levels of dopamine and serotonin increase 28.
Typical Users
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.
Safer Using – Piperazines
Because they affect the brain, the drugs cause a wide range of sensations and experiences. The drugs influence brain function by acting on chemicals called neurotransmitters, which can have profound effects on mood, learning, perceptions, and movement. And Sweetsur, P. (2007), ‘The prevalence of use, dependency and harms of legal ‘party pills’ containing benzylpiperazine (BZP) and trifluorophenylmethylpiperazine (TFMPP) in New Zealand’, Journal of Substance Use, Volume 12, No 3, pp. 213–224. (2007), ‘Legal piperazine-containing party pills – a new trend in substance misuse’, Drug and Alcohol Review, Volume 26, No 3, pp. 335–343.
The Risks
Many additives found in industrial chemicals may be toxic or even fatal if consumed. The “mystery ingredients” that are mixed in with it may add to that risk. TFMPP interacts with the serotonergic system through 5-ht type 1 and type 2 receptors. If someone falls unconscious while on piperazines, place them in the recovery position and seek medical attention. If you are concerned or someone experiences chest pain on piperazines, seek medical attention. How long the effects last and the drug stays in your system depends on how much you’ve taken, your size and what other drugs you may have also taken.
10 LC-DAD Analysis—Analytical Limits
Tissue from caudate (for DAT assay), or from whole brain minus cerebellum and caudate (for SERT assay), was homogenized in ice-cold 10% sucrose containing 1 μM reserpine. For DAT-mediated release assays, 3H1-methyl-4-phenylpyridinium (3HMPP+) was used as the radiolabeled substrate; 100 nM desipramine and 100 nM citalopram were added to prevent uptake of 3HMPP+ into NE and 5-HT nerves. For SERT-mediated release assays, 3H5-HT was used as the radiolabeled substrate; 100 nM nomifensine and 100 nM GBR12935 were added to the sucrose solution to prevent uptake of 3H5-HT into NE and DA nerve terminals. Synaptosomal preparations were incubated to steady state with 5 nM 3HMPP+ (60 min) or 5 nM 3H5-HT (60 min) in Krebs-phosphate buffer (pH 7.4), plus 1 μM reserpine. Subsequently, 850 μl of synaptosomes preloaded with 3Hligand were added to polystyrene test tubes that contained 150 μl of test drug in assay buffer plus 1 mg/ml BSA. After 5 min (3H5-HT) or 30 min (3HMPP+) the release reaction was terminated by dilution with 4 ml wash buffer followed by rapid vacuum filtration.
In contrast, the rise in extracellular 5-HT produced by BZP/TFMPP was similar to the additive effects of BZP plus TFMPP. Several rats receiving the high-dose combination developed seizures and subsequent ataxia. Although the seizures produced by BZP/TFMPP were short-lived and rats recovered completely, we did not investigate this phenomenon further due to animal welfare concerns. When BZP and TFMPP were incubated together during in vitro release assays, BZP did not alter ability of TFMPP to release 3H5-HT, and TFMPP did not alter the ability of BZP to release 3HMPP+ (data not shown).
The recreational use of piperazine derivatives can result in acute or chronic poisoning. The article describes methods using liquid chromatography techniques for the independent detection of piperazine designer drugs in biological and non-biological matrices. The benefit of the LC-MS method is the high sensitivity of determinations, while the LC-DAD method ensures high reproducibility of results. The LC-MS method also confirmed the reproducibility of the main fragmentation patterns for the tested compounds. The addition of deuterated analogues as internal standards to the tested samples ensured reproductible quantification.
- Furthermore, it has a great impact on various behavioral activities such as aggression, avoidance, anxiety, sexual activities, feeding and accommodation.
- The suggestion that BZP and other piperazine derivatives are extracted from the pepper plant may arise from confusion with the unrelated substance piperine, a constituent of black pepper (Piper nigrum).
- Because piperazine abuse has been recognized only recently, specific programs for rehabilitation have not yet been developed.
- Many participants had reduced the frequency with which they used BZP-party pills due to adverse effects.
Metabolic Interactions With Piperazine-based ‘party Pill’ Drugs
Therefore, we determined the most frequently occurring NPS in The Netherlands and combined this with data regarding drug-related intoxications. Data from the Drugs Information and Monitoring System (DIMS) and the Dutch Poisons Information Centre (DPIC) were combined and jointly analyzed. The number of drug samples submitted to DIMS for analysis containing NPS increased from 22 in 2007 to 431 samples in 2013. The most frequently submitted NPS in 2013 included 4-bromo-2,5-dimethoxyphenethylamine (2C-B), 4-fluoroamphetamine (4-FA), methoxetamine (MXE) and 6-(2-aminopropyl)benzofuran (6-APB). From 2012 onwards, the number of NPS bought as drug of choice exceeded those appearing as adulterants in established drugs.
The LC-DAD chromatogram of tested piperazine derivatives obtained with this method is shown in Figure 2 (intensity versus retention time). A good chromatographic separation of tested compounds was obtained under the above-mentioned chromatographic conditions. An exemplar chromatogram of the tested piperazine derivatives is shown in Figure 1 (intensity versus retention time). Originally, BZP was synthesised by the Wellcome Research Laboratories as a potential anthelminthic but was found to have antidepressant qualities. However, it was also found that BZP had amphetamine-like qualities and could cause hyperactivity and a reduction in reaction times in ‘shock avoidance studies’. BZP – acts to increase serotonin in the central nervous system and prefers serotonin 5-ht type 1 receptors.
Kinetic constants for N-demethylation derived from the single enzyme Michaelis-Menten model did not differ between the two groups. Troleandomycin and erythromycin selectively inhibited N-demethylation in both extensive and poor metabolizers. The kinetics of formation of dihydromorphine in both groups were best described by a single enzyme Michaelis-Menten model although inhibition studies in extensive metabolizers suggested involvement of two enzymes with similar K m values. The kinetic constants for O-demethylation were significantly different in extensive and poor metabolizers.
