Pyrazolam

Benzodiazepine

Pyrazolam (SH-I-04)[2] is a benzodiazepine derivative originally developed by a team led by Leo Sternbach at Hoffman-La Roche in the 1970s.[3] It has since been "rediscovered" and sold as a designer drug since 2012.[4][5][6][7][8][9][excessive citations]

Quick Facts Clinical data, Routes ofadministration ...

Pyrazolam has structural similarities to alprazolam[10] and bromazepam. Unlike other benzodiazepines, pyrazolam does not appear to undergo metabolism, instead being excreted unchanged in the urine.[4]

United Kingdom

In the UK, pyrazolam has been classified as a Class C drug by section 5 of the May 2017 amendment to The Misuse of Drugs Act 1971 along with several other designer benzodiazepine drugs.[11]
