Introduction

Flubromazolam (JYI-73) is a triazolobenzodiazepine (TBZD), which are benzodiazepine (BZD) derivatives.

Flubromazolam is reputed to be highly potent, and concerns have been raised that clonazolam and flubromazolam in particular may pose comparatively higher risks than other designer benzodiazepines, due to their ability to produce strong sedation and amnesia at oral doses of as little as 0.5 mg. Life-threatening adverse reactions have been observed at doses of only 3 mg of flubromazolam.
