One of the serious adverse reactions of Phenazepam is addiction, which can develop even if the dosage regimen is followed. And after long-term treatment with the drug, a strong dependence occurs, accompanied by severe nervous disorders. The standard course of treatment with Phenazepam is on average 2 weeks. During this short period of time, the patient does not have time to develop dependence on the medication. Accordingly, Phenazepam withdrawal syndrome does not occur, which is very important. For some diseases, doctors prescribe a period of therapy within 1-2 months.

- Taking Phenazepam simultaneously with alcoholic drinks leads to a decrease in the effectiveness of the drug, an increase in its toxic effect, and the development of overdose symptoms.
- Age, sex, observations (i.e., symptoms, death scene information etc.), detected concentrations in biological matrices and co-exposure concentrations are also displayed.
- When the drug is administered into a vein, the “lethal” dose is 10 ml.
- In the United State, as per the Food and Drug Association (FDA), there is no authorized medical use for this medication.
- The drug demonstrated a high degree of protein binding and low hepatic clearance, suggesting its potential for a prolonged elimination half-life in vivo 73,74,75.
People taking long-lasting benzodiazepines generally have greater success tapering off. With certified fomentation, dread, disquiet, treatment starts with a fragment of 3 mg/day. Subsequently quickly developing the fragment to acquire a strong impact.
Who Is At Risk When Taking Phenazepam?
Furthermore, there have been sporadic reports of the use of these designer BZDs as either adulterants or diluents in heroin or other synthetic opioids or cannabinoids, with consequent respiratory depression documented 8, 213, 214. A review of 197 trip reports of 10 different DBZs categorized and analyzed their most commonly reported effects 4. The 10 drugs reviewed were clonazolam, deschloroetizolam, diclazepam, etizolam, flubromazepam, flubromazolam, meclonazepam, metizolam, nifoxipam, and pyrazolam 4. Of these drugs, flubromazepam, flubromazolam, clonazolam, and meclonazepam were the most potent 4.
Although meclonazepam functions as a potent anti-parasitic agent, its sedative side effects have prevented its use. Two double-blind placebo-controlled studies reported arousal, psychomotor performance, and subjective mood following single oral doses of 1, 2, and 4 mg of meclonazepam 94,95. 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.

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. Phenazepam is a potent tranquilizer of the benzodiazepine group, which has a pronounced sedative, anxiolytic, and hypnotic effect. Due to the inhibitory effect of Phenazepam on the nervous system, its effectiveness in the treatment of many neurological and psychopathic diseases and sleep disorders is ensured. At the same time, the drug has a wide list of contraindications and can cause serious adverse reactions, including nervous disorders.

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.
How Long Do Its Effects Last?
The mechanism of the effect of phenazepam is connected with the decreased excitability of the subcortical centers of the brain and with the inhibition of the interaction between them and the cerebral cortex. Taking Phenazepam simultaneously with alcoholic drinks leads to a decrease in the effectiveness of the drug, an increase in its toxic effect, and the development of overdose symptoms. In combination with alcohol, the depressant effect is enhanced, which is dangerous not only for the health, but also for the life of the patient. Exceeding the doses prescribed by the doctor leads to severe intoxication of the body, accompanied by severe depression of consciousness, cardiac and respiratory activity. There is a high risk of coma, death, which can be caused by cardiac or respiratory arrest caused by the drug.
Benzodiazepine medications are sedative-hypnotics, meaning they create calming or tranquilizing effects. Because of this, these drugs are prescribed to treat anxiety, insomnia, panic and seizure disorders, and symptoms of alcohol withdrawal. The same actions that make these medications valuable within treatment also entice drug users. 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.

Benzodiazepine use has been linked to increased risks of suicide and suicidal ideation (thoughts of suicide). Chronic use of these drugs may change a person’s ability to feel emotions. Some people struggle to feel any emotions at all, which is a state referred to as emotional anesthesia. Like all forms of drug use, individuals who use benzodiazepines frequently experience an extreme loss of quality of life. In many cases, the need to use the drug becomes so intense that it overrules a person’s desire to take care of their family or fulfill other obligations, such as those relating to work or school.
In addition to these drugs and substances, phenazepam should not be combined with other benzodiazepines due to the increased risk of respiratory depression. Examples of other benzodiazepines include diazepam (Valium), clonazepam (Klonopin), and alprazolam (Xanax). The risk of addiction may occur when phenazepam is combined with other substances. Additionally, the drug may be snorted or smoked, greatly increasing the side effects and potential of a fatal overdose. Acute withdrawal from benzodiazepine drugs can become very dangerous, which means that professional treatment is necessary (medical detox). Certain individuals may experience withdrawal so severe that their life is in jeopardy.
There are no further data about clinical, pharmacological or toxicological properties. Clobromazolam is not currently controlled under the 1971 United Nations Convention on Psychotropic Substances or the 1961 Single Convention on Narcotic Drugs. 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.
- However, medications with a short half-life include alprazolam (Xanax), lorazepam (Ativan), and triazolam (Halcion).
- In one, a urine sample was analyzed through liquid chromatography-mass spectrometry to detect etizolam or flubromazolam, as they were above the negative control but also less than the calibrator value of the immunoassay 106.
- Flualprazolam was first identified in 89.8 grams of pale beige powder seized by Swedish police in Linköping on 29 November 2017.
- It is metabolized by the hepatic cytochrome P450 enzymes into various metabolites.
- The substance was analytically confirmed by GC-MS analysis 70, 109.
How Do People Take It?
The rising use of designer benzodiazepines (DBZD) is a cat-and-mouse game between organized crime and law enforcement. Non-prohibited benzodiazepines are introduced onto the global drug market and scheduled as rapidly as possible by international authorities. In response, DBZD are continuously modified to avoid legal sanctions and drug seizures and generally to increase the abuse potential of the DBZD. This results in an unpredictable fluctuation between the appearance and disappearance of DBZD in the illicit market.
Designer Benzodiazepines
However, he continued to use clonazolam and nonprescribed alprazolam, and his maintenance therapy with methadone was discontinued because of his continued use of benzodiazepines. This subsequently led to his return to using IV heroin, but he then self-referred himself to the clinic of the doctors who wrote this case presentation for withdrawal management. He was able to undergo successful buprenorphine induction for his heroin withdrawal management and benzodiazepine withdrawal management for three months.
A retrospective analysis of benzodiazepine prescriptions in 2008 yielded results that compared long-term prescriptions and total prescriptions by age category 8. It was found that the percentage of benzodiazepine users increases with age, and its use was nearly twice as prevalent in women compared with men 8. The fraction of long-term prescriptions also increased from 14.7% in the 18 to 35-year-old category to 31.4% in the 65 to 80-year-old category 8. This presents a concern for benzodiazepine-related risks of falls, fractures, and motor vehicle collisions 17,18,19.
