Meclonazepam[1] ((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.[2] It has sedative and anxiolytic actions like those of other benzodiazepines,[3] and also has anti-parasitic effects against the parasitic worm Schistosoma mansoni.[4]

Meclonazepam was never used as medicine and instead appeared online as a designer drug.[5][6]

Legal Issues[edit]

United Kingdom[edit]

In the UK, meclonazepam 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.[7]
