In order to decrease the availability of these substances in the global illicit drug market, more effort is needed by early warning agencies to reduce the timing between formal notifications and scheduling decisions. Further studies, professional training and analytical development are required to reduce the undercounting and underreporting of the cases in order to obtain robust and consistent epidemiological data. 7-Bromo-5-(2-fluorophenyl)-1,3-dihydro-2H-1,4-benzodiazepin-2-one, well known as flubromazepam, was detected for the first time in ten seized capsules in Germany and reported to the EMCDDA in March 2013 49. Four subjects were admitted to the ED in a profound state of agitation and delirium, followed by rigidity and CNS depression. In one case, flubromazepam’s depressant effect was mitigated by the presence of methoxyphenidine.

That happens with some new anabolic steroids, routinely used by athletes or body builders to get their “edge.” They buy them online, like the effects, tell their friends — and a successful “product” begins its run. It’s occasionally used as a recreational drug in the U.S. for its euphoric effects. However, abusing phenazepam can lead to severe adverse effects and be fatal. Using the drug in this way can lead to overdose or death, especially in high doses. Phenazepam is sometimes used as a recreational drug for its euphoric effects. It’s also used for its ability to enhance the effects of opioids, which can be extremely dangerous.
It has appeared as a cutting agent, notably in heroin during the shortage of 2010. As a result, seizures of phenazepam still occasionally take place in the UK 3. Phenazepam was previously sold and marketed as a ‘legal high’ or as fake Valium 1. The efficacy of Mel in patients with drug addiction as a treatment of alcohol dependence has also been demonstrated.
Novel Designer Benzodiazepines: Comprehensive Review Of Evolving Clinical And Adverse Effects
Bromazolam is also structurally similar to pyrazolam, where the pyridinyl group has been replaced with a phenyl group. Moreover, bromazolam is the brominated version of the internationally controlled substance alprazolam 115, 153. There are further data about clinical, pharmacological or toxicological properties. Bromazolam is not currently controlled under the 1971 United Nations Convention on Psychotropic Substances or the 1961 Single Convention on Narcotic Drugs.
Who Is At Risk When Taking Phenazepam?
Sedative effects peaked at 3 h, but moderate sedation persisted until 6 h post-ingestion 95. New research targets involve investigating new DBZs that maintain anti-parasitic effects while mitigating the significant alterations in mood and consciousness. Clinical and forensic toxicologists are on the front line, in cooperation with public health safety institutions, to identify emerging DBZD in cases of intoxication, drug offenses and unexplained deaths.
SOCIAL & LIFESTYLE
In February 2016, a young man was found dead in an advanced state of putrefaction next to five plastic bags labelled pyrazolam, diclazepam, 3F-phenmetrazine, 1-(2-fluorophenyl) propan-2-amine and diphenhydramine hydrochloride, as well as one unlabelled bag. Asphyxia promoted by polydrug intoxication was listed as the cause of death. As with other sedatives, in case of abrupt discontinuation following prolonged use, severe withdrawal symptoms may occur. While certain NPS belonging to the BZD class possess pharmacological profiles similar to controlled pharmaceutical BZDs, clinical and pharmacological profiles of current emerging BZDs are still not well-described. Therefore, there is a need to increase clinicians’/public health knowledge/awareness, to incentive harm reduction strategies.
- The data in this study prove concerning, as it suggests that DBZs require a higher dose to be detected than it does to cause significant impairment.
- Flualprazolam appears to be marketed as ‘fake’ alprazolam (labelled as ‘Xanax®’ or Xanor’ tablets) and some psychonauts defined it as the “king of the RC benzos” (i.e. the king of the research chemicals benzodiazepines) 54, 199, 200.
- People taking long-lasting benzodiazepines generally have greater success tapering off.
- Another case study of a 36-year-old male with a long-standing history of psychiatric disorders presented to an inpatient psychiatric facility with worsening anxiety that he attempted to manage with small doses of flubromazolam 75.
- Phenazepam is well known as a psychotropic and anticonvulsive drug.
Benzodiazepine Overdose
Three children were found drowsy and wobbly after eating colored pills thought to be candies. In addition, a subject was found unconscious next to a syringe of heroin. Three patients with psychiatric disorders presented at an outpatient department for etizolam detoxification after exhibiting tolerance and withdrawal. Etizolam was prescribed or illegally obtained in one case and was taken at supratherapeutic doses.

Phenazepam is used in the treatment of neurological disorders such as epilepsy, alcohol withdrawal and insomnia. It can be used as a premedication before surgery as it augments the effects of anesthetics and reduces anxiety. Alprazolam triazolobenzophenone has been firstly identified in a seizure of 1000 grams of white powder, seized at Madrid Airport in March 2014 by Customs authorities in a package that had arrived from India; it also contained paracetamol. The compound was identified and characterised using the gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) by the Spanish National Focal Point 79. There are limited anecdotal reports from psychonaut fora but it is supposed to exert an effect similar to that of alprazolam 54.
Counterfeit Xanax (alprazolam) and erimin-5 (nimetazepam) tablets containing etizolam, flualprazolam and phenazepam were also seized in the United States (US), Australia, Singapore and Malaysia 30,55,56. Flualprazolam is a 1,2,4-triazolobenzodiazepine, where the diazepine ring is fused to a triazole ring. Flualprazolam is the 2-fluoro derivative of alprazolam and it differs from triazolam by replacement of the chlorine with fluorine at the 2-position (ortho position) on the phenyl ring attached to the benzodiazepine moiety. Both substances, alprazolam, and triazolam, are under international control. Flualprazolam is also structurally related to flubromazolam, formally notified to the EMCDDA in 2014 152, from which it differs due to the replacement of bromine with chlorine at the 8-position on the benzodiazepine moiety 96, 195.
27 Flualprazolam
Benzodiazepines are most commonly used as anti-anxiety or sleeping pills, but relax muscles and give many people a “buzz.” All benzodiazepines can be abused, not only causing sedation, disinhibition, and confusion, but, at high doses, death. The problem is particularly acute when adding alcohol, which is how many people committed suicide in the 1960’s and 70’s, and which has more recently been inadvertently fatal for some. Several celebrities have been found with a combination of benzodiazepines and alcohol at their post-mortem. People also do not realize that alcohol at midnight has two-to-three times the psychomotor effects of drinks consumed at 6 pm. That’s scary because relatively low, often-forgotten doses of long-acting drugs like phenazepam (“Gosh, I took that days ago”) can, in combination with late-night alcohol, lead to fatal accidents. Flunitrazolam is a triazolo BZD, structurally related to the previously notified clonazolam (clonitrazolam), differing by the replacement of 2-chloro with 2-fluoro on the phenyl group.
Furthermore, there were 28 additional deaths in which flualprazolam was not listed as the cause of death; these include 5 decedents from Finland, 13 from Sweden and 10 from the US. Flualprazolam blood concentrations ranged from 3 ng/mL to 620 ng/mL 101,102. The substance was analytically confirmed by the Swedish National Forensic Centre using GC-MS 9, 135, There are no clinically significant anecdotal reports from psychonaut fora describing clinical effects of norfludiazepam so far.
Following the UK Advisory Council on the Misuse of Drugs (ACMD) advice, the Home Office imposed a ban (dated 22 July 2011) under the Open General Import License on the importation of phenazepam 23-25. Following the ACMD recommendation, phenazepam became controlled in the UK, like other BZDs, as a Class C drug from June 2012. The recreational/unauthorized use of phenazepam has been reported during the recent last years, particularly in the USA, New Zealand, and some European countries, particularly in Scandinavian countries (i.e., Finland, Norway and Sweden) 16, 26-28. The half-life of clonazolam is thought to be around 3.6 h and it is extensively metabolized and is mainly excreted as its amino and acetamino metabolites 86. The main metabolites are 7-amnoclonazolam, hydroxyclonazolam, and 7-acetamindoclonazolam. As with all benzodiazepines, clonazolam acts as a GABA receptor agonist, increasing the time that chloride channels are open 70.
Moderate to considerable motor and functional impairments were evident in all drivers. Heide et al. reported one additional DUID of a young driver submitted for CTI 86 who also had a phenazepam blood concentration of 120 ng/mL. Of sixty deaths reported, phenazepam alone was listed as the sole cause of death in two cases, while the remaining were attributed to accidental overdose due to polydrug toxicity. It was identified in Sweden in 10 seized white tablets labelled “XANAX” and reported to EMCDDA in October 2014 50. Eighteen patients were admitted to the ED in a severe state of CNS depression with functional and motor impairment. In 16 cases, flubromazolam was the sole drug detected, while in 2 cases subjects were also positive for meclonazepam.
