EMCDDA. New report highlights public health risks and increasing availability of ‘designer benzodiazepines’ in Europe 

New benzodiazepines, which are not controlled by international drug laws, come under the spotlight today in a new report released by the EU drugs agency (EMCDDA) (1). Often marketed as ‘designer benzodiazepines’, these substances are sold as ‘legal’ replacements for controlled benzodiazepines and are becoming increasingly available in Europe. They are monitored by the agency as new psychoactive substances (NPS) through the EU Early Warning System (EWS).

The EMCDDA currently monitors 30 new benzodiazepines, over 80% of which were detected for the first time between 2014 and 2020. Despite this relatively large number, the new benzodiazepine market in Europe is currently dominated by etizolam and flualprazolam — although this may change, as both substances were placed under international control in November 2020. In 2019, 1 240 seizures of new benzodiazepines were reported by the EU Member States (around 5% of NPS seizures). (EMCDDA, News release No 6/2021, Lissabon, 09.06.2021

EMCDDA. New benzodiazepines in Europe – a review

Summary

This report provides a technical review of the current body of knowledge regarding new benzodiazepines that are monitored by the EU Early Warning System. The aims of this report are to strengthen situational awareness of new benzodiazepines in Europe, and to help stakeholders prepare for and respond to public health and social threats caused by such substances.

Mixing meds: Weighing the pros and cons of adding benzodiazepines to buprenorphine treatment for individuals with opioid use disorder

Benzodiazepines (a class of sedative medications best known by brand names like Valium, Xanax, and Klonopin) may be prescribed to patients who are receiving buprenorphine treatment for opioid use disorder (an opioid agonist medication best known in formulation with naloxone, marketed as Suboxone). Clinicians accept that there are both risks, and potential benefits associated with combining these medications. To help aid clinical recommendations, Park and colleagues examined some of the risks and benefits associated with prescribing buprenorphine and benzodiazepines together using government records from the state of Massachusetts.

Clonazepam used as single antiepileptic drug to treat people with newly diagnosed epilepsy

Certainty of the evidence

So far, the evidence on the efficacy and tolerability of clonazepam used as a single antiepileptic drug for the treatment of epilepsy is scarce and of very low certainty; hence insufficient to base decisions on its use in monotherapy.
