Recently, several evaluations of the cytotoxic effect of piperazine designer drugs were performed. These compounds have been shown to be potentially cardiotoxic 42,43, hepatotoxic 14,44, neurotoxic 38,45,46, nephrotoxic 33 and endocrine disrupting 10,47. All piperazine designer drugs can result in dangerous health problems 10,19,26,40. Even accidental ingestion can lead to severe poisoning or death 26,29,37.
Legal Status TFMPP
In December 2007, TFMPP was added to Israel’s list of controlled substances, making it illegal to buy, sell, or possess. Animal research has shown that BZP triggers the release of neurotransmitters called dopamine and norepinephrine, two natural stimulants that the body produces on its own. TFMPP acts by stimulating nerve receptors sensitive to serotonin, another neurotransmitter. If the police catch people supplying illegal drugs in a home, club, bar or hostel, they can potentially prosecute the landlord, club owner or any other person concerned in the management of the premises. From 1 February 2023, CBD has been listed as a dangerous drug under DDO. Gobbi, M., Moia, M., Pirona, L., Ceglia, I., Reyes-Parada, M., Scorza, C., Pennini, T.
Latest Data
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). 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). 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).
- Most participants (91.7%) had engaged in polydrug usage and 1,670 combinations of drugs were reported.
- However, mass spectrometry does not distinguish mCPP from its isomers (oCPP and pCPP).
- The Table 11 shows the piperazine derivatives as metabolites of therapeutic drugs.
- As of early 2005, other chemical substances related to BZP were being investigated for possible uses in the treatment of depression, psychosis, epilepsy, and severe pain.
1 LC-MS Method
For CYP1A-mediated pathways, all the commonly used experimental models are appropriate except probably the dog. On the contrary, the dog seems to be suitable for modelling of processes depending on the CYP2D. With CYP2C, which is possibly the most large and complicated subfamily, the systems based on monkey (Maccacus rhesus) may be a good representative. Detailed studies on activities with individual isolated CYP forms are needed to understand in full all aspects of inter-species differences and variations. In 2003, Drug Topics reported that the DEA was working to have both BZP and TFMPP added to the list of Schedule I drugs under the CSA. Buyers got around this specification by lying about the intended use of the drug.
Benzylpiperazine
Additionally, the available immunoassays for known abused drugs cannot easily detect piperazines 11,16,17,62. Wherever circumstances indicate drug use, the positive and negative test results should be confirmed by other techniques, as observed in studies with amphetamines 71,72. Till now, various modern NPS detection methods, which use liquid chromatography (LC) or gas chromatography (GC), have been proposed 3,12,15,41,69,70,73,74,75,76,77,78. 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. Widely used GC-MS technique is quite often chosen for systematic toxicological analysis (STA), although the preparation of samples of piperazine derivatives requires derivatization, which significantly extends the time of determinations 41,64,77. LC-MS is seen as a complementary technique to GC-MS and can be successfully used to for the detection of unstable, low-dosed or polar drugs, specifically in biological fluids 79.
In 2005 the New Zealand government created legislation intended to regulate the drug, but as potential health risks from BZP consumption became apparent, subsequent legislation was introduced to prohibit the substance. The following review briefly covers the scientific and legal background of benzylpiperazine with particular reference to New Zealand, the country in which it was most popular. At the high dose of BZP/TFMPP (10 mg/kg, i.v.), extracellular DA was elevated to a greater extent than the summed effects of BZP and TFMPP alone, suggesting a synergistic effect on DA transmission when the drugs are combined (see Table 1). 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.

(2003), ‘Screening for and validated quantification of amphetamines and of amphetamine- and piperazine-derived designer drugs in human blood plasma by gas chromatography/mass spectrometry’, Journal of Mass Spectrometry, Volume 38, No 6, pp. 659–76. The piperazine derivatives are not chemically similar to any of the more common substances of misuse, but have a more distant connection with phencyclidine and with 1-phenylethylamine and its derivatives. 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).

Animal studies have demonstrated that BZP stimulates the release and inhibits the reuptake of dopamine, serotonin and noradrenaline. BZP appears to be metabolised by cytochrome P450 (possibly involving the CYP2D6 iso-enzyme) and catechol-O-methyl-transferase (COMT). These systems are prone to genetic polymorphisms, so potential inter-individual differences may occur.
In a side-by-side comparison with MDMA, we demonstrated that BZP is a releaser of 3HMPP+, whereas TFMPP is a releaser of 3H5-HT. Similar to MDMA, the in vitro releasing properties of BZP and TFMPP are mediated by substrate activity at DATs and SERTs, since low doses of selective transporter blockers can antagonize the effects of these piperazines (see Figures 2 and 3). It is noteworthy that BZP and TFMPP are somewhat less potent than MDMA with respect to stimulating 3Hmonoamine release in vitro.
Drugs A – Z
The benefit of the LC-MS method used is the high sensitivity of the determinations. On the other hand, the advantage of the LC-DAD method is the high repeatability of the results. Processing the sample without the need for derivatization significantly simplifies and shortens the analysis time, especially compared to the methods, which are based on GC-MS 41,77. The short time of the analysis of the serum or urine samples will allow us to assess the current health status of the patient, as opposed to the analyses carried out, i.e., in the hair matrix 69,70. Until now, other studies using LC-MS, GC-MS, and LC-DAD did not explicitly target the compounds from the tested group 12,15,69,75,76. The methods presented in the article may complement each other for the research on piperazines or they may be used independently.
Emerging clinical evidence demonstrates that MDMA can cause 5-HT dysfunction in humans under some circumstances (Parrott, 2002). Moreover, habitual users of MDMA exhibit psychological problems, memory disturbances, and cognitive impairments that could be secondary to drug-induced 5-HT deficits (Morgan, 2000). Stimulants mediate the actions of dopamine, norepinephrine and/or serotonin, mimicking the effects of traditional drugs such as cocaine, amphetamine, methamphetamine, and ecstasy. Opioids belong to a chemically diverse group of central nervous system depressants.
- The physical effects of piperazine use include nausea, vomiting, redness of the skin, stomach pains, thirst, dry mouth, frequent urination, bladder infection or irritation, severe headaches, and “hangover” feelings lasting up to two days.
- However, we have noted inconsistencies between in vitro and in vivo effects of monoamine releasers in prior studies.
- In the late 1990s, BZP emerged in New Zealand as a ‘legal alternative’ for MDMA and methamphetamine 3.
- Piperazines are a very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines.
- Because BZP and TFMPP are reportedly coadministered by human drug users, we examined the effects of these agents alone and in combination.
- Sources of the reagents required for the in vitro release assays and the in vivo microdialysis methods have been previously reported (Baumann et al, 2001; Rothman et al, 2001).
Effects Of MDMA Administration In Vivo
Amphetamine-like effects include euphoria, alertness, a reduced need for both food and sleep, a heightened sense of touch and other pleasurable sensations, and a sense of emotional closeness with others. At higher doses, though, users have reported stomach pain, vomiting, and feelings of extreme anxiety and paranoia. A tingling feeling on the surface of the skin may make users feel as if insects are crawling all over them. Some users end up in emergency rooms panic-stricken, screaming, and suffering from extreme dehydration. These letter ratings are somewhat similar to the scheduling of drugs by number in the United States.
The role of individual hepatic cytochrome P450 (CYP) enzymes in drug metabolism and the factors that modulate CYP activity are becoming increasingly well understood. These advances have resulted in a better understanding of drug-drug and drugfood interactions and an enhanced capacity to predict drug interactions that may occur with new drugs. This final article in the series describes the issues and principles that are important in identifying and assessing drug interactions that involve CYP enzymes.
However, with an increased understanding of drug-metabolizing enzymes and their roles in the metabolism of specific drugs, it is possible to apply a more mechanistic approach to assessing DDIs. In particular, the possibility of extrapolation of results of clinical DDI studies with 1 drug known to be cleared by a particular drug-metabolizing enzyme to other drugs that are cleared by that same enzyme is attractive. Benzylpiperazine (BZP) and trifluoromethyl-phenylpiperazine (TFMPP) are both stimulants—substances that increase the activity of a living organism or one of its parts. Neither one of these compounds has any known medical use for humans, at least not in their existing chemical forms. BZP and TFMPP are substances known as intermediaries, meaning they are at a middle stage in chemical production. Because piperazines can dissolve fats, they are often used as cleaning solutions.
Before going into a coma, she consumed 10 liters of water in just 15 hours. The young woman experienced high blood pressure and brain swelling prior to her death. Former speed addicts who took BZP experienced an increase in blood pressure and short-term mental experiences similar to those brought on by amphetamines.
