Pyrazolam is a benzodiazepine derivative originally developed in the 1970s and subsequently “rediscovered” and sold as a designer drug starting in 2012. Pyrazolam has structural similarities to alprazolam and bromazepam. Unlike other benzodiazepines, pyrazolam does not appear to undergo metabolism, instead being excreted unchanged in the urine. Pyrazolam has anti-anxiety properties which are 12 times stronger than diazepam.
