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]
