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]

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]

Legal status

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]
