Some states have legislated a ban on particular classes of drugs, so that not-yet-created versions of older, toxic drugs will not themselves be legal. These more narrow versions of the Analog Act generally have more legal teeth. However, banning drugs of a chemical class not yet discovered is legally very difficult. Check out our blog posts and resource links for the latest information on substance abuse. If an overdose is suspected, seek urgent medical attention and contact 911 right away.

UN Single Convention On Narcotic Drugs
While binding or activity data are available for most of these compounds also, the assay conditions vary between sources, meaning that in many cases the values are not suitable for a direct comparison. In masochist, psychopathic, disquiet like and psychopathic states, the secret portion of the remedy 0.5-1 mg 2-3 times/day. Understanding 2-4 days, pondering the reasonableness and decency of the solution, the fragment might be reached out to 4-6 mg/day.
Phenazepam Risks
The study showed a significant impairment in cognitive and psychomotor functions in all doses exceeding 1 mg 95. 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. Clonazolam is considered a DBZ, a benzodiazepine analog found in the illicit drug markets with no medical use or FDA approval 75.
- On the productive psychotic symptoms genesis (acute delusional, hallucinatory, affective disorders) has practically no effect, it is rarely observed decrease in affective intensity, delusional disorders.
- There are limited anecdotal reports from psychonaut fora which describe it as “longer acting and slightly less potent than etizolam” 54.
- 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.
- In some cases, people have taken what they thought was a typical dose of Valium but was actually a high dose of phenazepam.
- Furthermore, a few states like Louisiana and Arkansas have passed a legislative policy classifying Phenazepam as a dangerous, controlled substance.
What Is The Duration Of Treatment With Phenazepam?
He was able to undergo successful buprenorphine induction for his heroin withdrawal management and benzodiazepine withdrawal management for three months. In the end, his cravings and worsening withdrawal symptoms resulted in a relapse of his DBZ use. Compared with classical BZD, these compounds produce strong sedation and amnesia, and they increase the risk of respiratory depression and death when used in combination with other CNS depressants 41,42. However, they are illicit, with a relatively short life cycle in the NPS market, the majority of DBZD have not undergone clinical trials and our knowledge of their pharmacokinetics and toxicity is lacking and limited to self-reported experiences 43,44. These substances are illegally manufactured, sometimes mimic legal medicines’ appearance, and are purchased inexpensively on the underground drug market through online platforms that facilitate anonymous trading and bypass regulatory systems 45,46.

The drug is not used in the UK as a medicine, but is available on prescription in Russia for the treatment of epilepsy, insomnia and neurological disorders. In order to avoid the development of drug dependence at course treatment duration Phenazepam application is 2 weeks (in some cases the duration of treatment can be increased up to 2 months). Like other benzodiazepines, phenazepam can be used as a chill-out drug.
- The term “DBZD” is a misnomer, as the class also includes BZD marketed in only some countries, metabolites of registered BZD and structural analogues of therapeutically approved BZD 32,33.
- Symptoms of intoxication were mainly characterized by CNS depression and a withdrawal syndrome.
- Thus, it is crucial for users to never consume large amounts or combine the use of multiple CNS-depressants.
- There are several anecdotal reports from psychonauts fora which describe it as “of extreme duration, with effects for larger doses reaching up to three days” 52, 54.
- The substance was analytically confirmed by the Swedish National Forensic Centre using GC-MS, GC-IRD, LC-HRMS and NMR 11.

Cloniprazepam shares structural similarities with the previously notified BZD clonazolam (clonitrazolam) and meclonazepam. Cloniprazepam is not currently controlled under the 1971 United Nations Convention on Psychotropic Substances or the 1961 Single Convention on Narcotic Drugs. Flubromazepam was first identified in a sample of capsules analysed by a German university forensic institute in March 2013 69, 70, 72, 73.

Unlike GABAA agonists that work directly on the receptor, BDZ increase the frequency of GABAA channel opening, depending only on the endogenously available GABA 8,9,10. Due to controlled neuronal inhibition and lower CNS depression risk, BZD rapidly replaced older medications such as barbiturates, meprobamate and chloral hydrate, becoming the most prescribed drug class in the world during the 1970s 11,12. Although they possess a high therapeutic index, BZD also come with several side effects, such as drowsiness, dizziness, fatigue, dysarthria, loss of coordination, headache and amnesia, and they have the potential of being addictive 5. Their use was recommended for a short treatment, i.e., 4–6 weeks for insomnia, but physicians prescribed BZD for months or years, with patients finding it difficult to stop taking these medications because of withdrawal symptoms 13,14,15,16. Controlled clinical trials confirmed that long-term administration produced tolerance and dependence 17,18.
Designer Benzodiazepines: A Review Of Toxicology And Public Health Risks
The data also exhibited that yearly single-agent exposures increased each subsequent year, starting at 26 in 2014 and ending at 112 in 2017. Clonazolam and etizolam were the two most common culprits of single-agent exposures throughout the study. The jump from 26 cases in 2014 to 112 cases in 2017 is approximately a 330% increase in incidence and should prompt general awareness of DBZs and their increasing prevalence 80. An in vitro analysis of flubromazolam sought to disclose many of these parameters 73. This analysis determined that its main metabolic pathway is hydroxylation by CYP3A4 and CYP3A5, generating α-hydroxy-flubromazolam and 4-hydroxy-flubromazolam as its predominant metabolites 73.
Thionordazepam differs from nordazepam due to the replacement of the oxygen with a sulfur and it differs from alprazolam due to the absence of the 1,2,4-triazole moiety 158. It was previously described in a 1963 patent by Hoffman-La Roche 158. The analysis and identification of the starting material and synthesis-related intermediates for alprazolam, including thionordazepam, using high performance thin layer chromatography is reported in the literature 159. There is no information available on the pharmacology and toxicology of thionordazepam. Thionordazepam is not currently controlled under the 1971 United Nations Convention on Psychotropic Substances or the 1961 Single Convention on Narcotic Drugs. Bromazolam is a triazolo-BZD structurally related to flubromazepam, from which it differs due to the absence of a fluorine in the 2-position on the phenyl ring.
How Do People Take It?

Phenazepam is mainly sold either as a fine white powder or as a liquid. Phenazepam costs between £18 and £20 for one gram of powder and £12.50 for a 20ml bottle of liquid phenazepam. The early origins of phenazepam are hazy, but it is likely that the first synthesis occurred in the USSR in the mid-1970’s, with the earliest mentions of it in Soviet medical literature coming from 1978. It was originally intended for use in treating psychological problems, but the discovery of its anti-convulsant properties led to it being investigated as a possible epilepsy treatment. But phenazepam is very strong and so it is easy to take too much and overdose.
As central nervous system (CNS) depressants, benzodiazepines can slow vital life support systems to deadly levels. When this happens, a person’s body temperature, blood pressure, breathing, and heart rates can no longer sustain life. Though not prescribed in the United States, flunitrazepam (Rohypnol) is sold illicitly on the streets. Used as a date rape drug, Rohypnol is a high-potency benzodiazepine with a relatively long half-life. When considering all benzodiazepines, phenazepam is most similar to clonazepam and bromazepam in terms of chemical structure, action and dosing. In masochist, psychopathic, uneasiness like and psychopathic states, the hidden segment of the prescription 0.5-1 mg 2-3 times/day.

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. Flubromazolam is a substituted BZD, structurally related to pyrazolam from which it differs due to the substitution of a 2-fluorophenyl instead of a 2-pyridinyl group at position 6. Moreover, it is the triazolo-analogue of flubromazepam and it is structurally related to alprazolam and triazolam 90-93. The substance has been researched in the patent literature for its anxiolytic properties and decreased sedative, hypnotic, and ataxic side-effects, but it does not appear to be licensed for medical use. Huppertz et al. 90 reported muscle relaxation, sedation, difficulty following and participating in conversation and partial amnesia in a healthy volunteer following intake of 0.5 mg of flubromazolam. A case-report described a 36-year-old male affected with a schizoaffective disorder, opioid use disorder, seizures, anxiety and a posttraumatic stress disorder who presented to an inpatient facility and reported flubromazolam abuse 93.
