Flubromazolam (JYI-73) [2] [3] [4] is a triazolobenzodiazepine (TBZD), which are benzodiazepine (BZD) derivatives. [5] [6] [7] [8] [9] [10] [11] Flubromazolam is reputed to be highly potent, and concerns have been raised that clonazolam and flubromazolam in particular may pose comparatively higher risks than other designer benzodiazepines, due to their ability to produce strong sedation and amnesia at oral doses of as little as 0.5 mg. [12] [13] Life-threatening adverse reactions have been observed at doses of only 3 mg of flubromazolam. [14]

Contents

Sweden

Flubromazolam has been classified as an illegal substance in Sweden after seizures by customs and police, as well as indications from the EMCDDA of wider use as a recreational drug. [15]

Switzerland

Flubromazolam is illegal in Switzerland as of December 2015. [16]

United Kingdom

In the UK, flubromazolam has been classified as a Class C drug by the May 2017 amendment to The Misuse of Drugs Act 1971 along with several other designer benzodiazepine drugs. [17]

Australia

In Australia, flubromazolam is Schedule 9 under federal law. [18]

United States

Flubromazolam is controlled in Virginia. On December 23, 2022, the DEA announced it had begun consideration on the matter of placing Flubromazolam under temporary Schedule I status. [19] Later on July 25, 2023, the DEA published a pre-print notice that Flubromazolam would become temporarily scheduled as a Schedule I controlled substance from 26 July 2023 to 26 July 2025. [20]

<span class="mw-page-title-main">Etizolam</span> Benzodiazepine analog drug

Etizolam is a thienodiazepine derivative which is a benzodiazepine analog. The etizolam molecule differs from a benzodiazepine in that the benzene ring has been replaced by a thiophene ring and triazole ring has been fused, making the drug a thienotriazolodiazepine.

<span class="mw-page-title-main">Meclonazepam</span> Chemical compound

Meclonazepam ((S)-3-methylclonazepam) was discovered by a team at Hoffmann-La Roche in the 1970s and is a drug which is a benzodiazepine derivative similar in structure to clonazepam. It has sedative and anxiolytic actions like those of other benzodiazepines, and also has anti-parasitic effects against the parasitic worm Schistosoma mansoni.

<i>N</i>-Desalkylflurazepam Benzodiazepine analog

N-Desalkylflurazepam is a benzodiazepine analog and an active metabolite of several other benzodiazepine drugs including flurazepam, flutoprazepam, fludiazepam, midazolam, flutazolam, quazepam, and ethyl loflazepate. It is long-acting, prone to accumulation, and binds unselectively to the various benzodiazepine receptor subtypes. It has been sold as a designer drug from 2016 onward.

Pyrazolam (SH-I-04) is a benzodiazepine derivative originally developed by a team led by Leo Sternbach at Hoffman-La Roche in the 1970s. It has since been "rediscovered" and sold as a designer drug since 2012.

<span class="mw-page-title-main">Diclazepam</span> Benzodiazepine medication

Diclazepam (Ro5-3448), also known as chlorodiazepam and 2'-chloro-diazepam, is a benzodiazepine and functional analog of diazepam. It was first synthesized by Leo Sternbach and his team at Hoffman-La Roche in 1960. It is not currently approved for use as a medication, but rather sold as an unscheduled substance. Efficacy and safety have not been tested in humans.

<span class="mw-page-title-main">Flubromazepam</span> Benzodiazepine designer drug

Flubromazepam is a benzodiazepine derivative which was first synthesized in 1960, but was never marketed and did not receive any further attention or study until late 2012 when it appeared on the grey market as a novel designer drug.

<span class="mw-page-title-main">3-Hydroxyphenazepam</span> Benzodiazepine medication

3-Hydroxyphenazepam is a benzodiazepine with hypnotic, sedative, anxiolytic, and anticonvulsant properties. It is an active metabolite of phenazepam, as well as the active metabolite of the benzodiazepine prodrug cinazepam. Relative to phenazepam, 3-hydroxyphenazepam has diminished myorelaxant properties, but is about equivalent in most other regards. Like other benzodiazepines, 3-hydroxyphenazepam behaves as a positive allosteric modulator of the benzodiazepine site of the GABAA receptor with an EC50 value of 10.3 nM. It has been sold online as a designer drug.

<span class="mw-page-title-main">Clonazolam</span> Benzodiazepine derivative research chemical

Clonazolam is a drug of the triazolobenzodiazepine (TBZD) class, which are benzodiazepines (BZDs) fused with a triazole ring. Although little research has been done about its effects and metabolism, it is sold online as a designer drug.

<span class="mw-page-title-main">MDMB-CHMICA</span> Chemical compound

MDMB-CHMICA is an indole-based synthetic cannabinoid that is a potent agonist of the CB1 receptor and has been sold online as a designer drug. While MDMB-CHMICA was initially sold under the name "MMB-CHMINACA", the compound corresponding to this code name (i.e. the isopropyl instead of t-butyl analogue of MDMB-CHMINACA) has been identified on the designer drug market in 2015 as AMB-CHMINACA.

<span class="mw-page-title-main">5F-APINACA</span> Chemical compound
