As with other sedatives, in case of abrupt discontinuation following prolonged use, severe withdrawal symptoms may occur. A warning from North Wales police in January 2011 was issued to warn residents about local drug dealers passing off large quantities of phenazepam as Valium (diazepam). The danger in situations such as this is that people may take larger amounts of phenazepam while unaware that what they are taking is around 20 times more potent than what they believe they are taking 3.

- Examples of other benzodiazepines include diazepam (Valium), clonazepam (Klonopin), and alprazolam (Xanax).

However, the drug is routinely prescribed in Russia and other Commonwealth of independent state (CIS) countries in much the same way and for the same indications as the more familiar benzodiazepines are in the western world. As one can see, the degree and severity of the experienced side effects grow with increasing the dosage of the medication used or when combined with other CNS-depressant drugs. Thus, it is crucial for users to never consume large amounts or combine the use of multiple CNS-depressants.

It is metabolized to the active metabolite 3-hydroxyphenazepam by different isoforms of CYP450 114,135. 3-Hydroxyphenazepam was identified in a seized white tablet and reported in October 2016 by Denmark. Three subjects were admitted to the ED after ingesting illicit phenazepam purchased on the Internet. Patients exhibited both motor and functional impairment and depressant effects. In May 2016, a patient was admitted to the ED after ingesting four tablets of 3-hydroxyphenazepam. There also are 19 DUID and a drug offense cases included in Table 1.

It has anxiolytic, sedative-hypnotic, anticonvulsant and central muscle relaxant effect. Among the 6500 autopsy cases, the DBZs etizolam, flubromazolam, phenazepam, and diclazepam were detected in 21 cases. Diclazepam, as also seen in the living cases, was the most prevalent DBZ detected. Overall, the concentrations of the DBZs detected were similar to the living cases, apart from flubromazolam. These results did differ from the living cases in that the ages ranged from 20 to 59 years old, and almost half of the cases were women.

Like most benzodiazepines, phenazepam has a phenyl ring in R5 which is substituted by chlorine in the R2′ group. Phenazepam also contains an oxygen group double bonded to R2 of its diazepine ring to form a ketone. This oxygen substitution at R2 is shared with other benzodiazepine drugs with the suffix -azepam.

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. Since the discovery of chlordiazepoxide in the 1960s, benzodiazepines have gained popularity due to their low toxicity and high safety profile compared with their predecessors, barbiturates. They are now routinely used to treat many psychiatric and neurological conditions.

After a swathe of overdoses, including being linked to several fatalities, and the wide availability of the substance on the internet, the UK government moved to ban the importation of phenazepam in July 2011. It was added to the list of controlled substances under the Misuse of Drugs Act 1971 in 2012. However, it is still manufactured in the Russian Federation, where it is available on prescription and (by some accounts) without a prescription in certain pharmacies. 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.
Limitations Of The Present Study

The drug is prescribed in a variety of dosages depending on the patient’s condition and how the treatment is progressing and how good the results are. As a rule, the course is started with 1 tablet/day, then the dosage is increased to 2-3 tablets per day.
