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. New Zealand has classified BZP-based party pills as a “Restricted Substance” by the Misuse of Drugs Act and restricted to those over 18 years.

Classification
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. 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. Conclusion Findings suggest that young people in this study were not suffering excessive or dangerous adverse effects.

Overdose And Toxicity Of Piperazines
Busts have been made for possession and use of piperazines throughout the United States, especially in California, Connecticut, and Texas. Teenagers and young adults who attend raves on a regular basis are the most frequent users of both BZP and TFMPP. Like ecstasy, piperazine has spread from the club scene to high schools and college campuses.

Neither BZP nor any other substituted piperazine is listed in the Schedules of the United Nations 1971 Convention on Psychotropic Substances. However, several members of this family have been proposed for critical review by the WHO in 2009. Following a risk assessment in 2007, a Council Decision of 2008 introduced controls on BZP in the European Union. There are no readily-available screening tests for mCPP or the other phenylpiperazine derivatives. In the mass spectrum, the principal ions (m/z) of mCPP are 154 (base peak), 196, 156, 56 and 138. However, mass spectrometry does not distinguish mCPP from its isomers (oCPP and pCPP).
Designer Drugs: Mechanism Of Action And Adverse Effects
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. The retained tritium was counted by a Topcount liquid scintillation counter (Perkin-Elmer, Downers Grove, IL). Dose–effect curves were generated for MDMA, BZP, and TFMPP by testing 8–10 concentrations of each drug in assays. Substrate reversal experiments were performed to verify that monoamine transporter sites were involved in the releasing properties of drugs.

Latest Data
Piperazines are capable of disrupting a person’s ability to think, communicate, and act sensibly. As with other mind-altering substances, use of BZP or TFMPP may jeopardize work or school performance, ruin relationships, and increase the likelihood of involvements in accidents. Loss of control or inappropriate behavior may cause other people to view the user with suspicion. Addiction can lead the user to abandon educational goals and engage in criminal activity.
Is It Dangerous To Mix With Other Drugs?

The great advantage of the proposed methods is that they can be used to monitor 1-aryl-piperazines as metabolites of therapeutic drugs. Monitoring concentrations of piperazine derivatives as metabolites could contribute to the safety of the treatment. The Table 11 shows the piperazine derivatives as metabolites of therapeutic drugs. The developed methods were used to determine piperazine compounds in enriched biological samples.

Alternative chemical names for BZP include 1-benzyl-1,4-diazacyclohexane, N-benzylpiperazine and, less precisely, benzylpiperazine. Street names have included A2, Legal X and Pep X. In New Zealand, piperazine derivatives were commonly known as ‘party pills’. Aims Decisions on whether and how to ‘schedule’ drugs (i.e. to determine their legal status and penalties to be applied for sale or possession) are often heavily criticized. We sought to assess more comprehensively the results of such decisions for newly emerging drugs.
Former speed addicts who took BZP experienced an increase in blood pressure and short-term mental experiences similar to those brought on by amphetamines. Results of experiments conducted on rhesus monkeys, published in Drug and Alcohol Dependence in 2005, confirmed that BZP is as addicting as amphetamines. Other animal experiments suggest that the use of piperazines can actually inhibit learning.

These include among others 1-(3-chlorophenyl) piperazine (mCPP), 1-(3-trifluoromethylphenyl) piperazines (TFMPP), 1-benzyl-4-methylpiperazine (MBZP), 1-(4-fluorophenyl) piperazines (pFPP) and 1-cyclohexyl-4-(1,2-diphenylethyl) piperazine (MT-45). Difficulty in assessing the results obtained can be due to the fact that the metabolic processes of related therapeutic drugs may result in the detection of 1-aryl-piperazines in the biological matrices 86. Piperazine derivatives, detected as metabolic products, account for about 10% of the applied dose.
Transporter-mediated release assays were carried out as previously described with minor modifications (Rothman et al, 2001). 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.

In their pharmacological profile, piperazine derivatives increase the level of dopamine (DA), serotonin (5-HT) and norepinephrine (NA), and block the neuronal uptake of these compounds 11,33. Elevated levels of these neurotransmitters can cause a variety of desired as well as undesirable behavioral and clinical effects 2,21. 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.
