Cinazepam

Cinazepam (BD-798, sold under brand name Levana) is an atypical benzodiazepine derivative.[1] It produces pronounced hypnotic, sedative, and anxiolytic effects with minimal myorelaxant side effects.[2][3][4] In addition, unlike many other benzodiazepine and nonbenzodiazepine hypnotics such as diazepam, flunitrazepam, and zopiclone, cinazepam does not violate sleep architecture, and the continuity of slow-wave sleep and REM sleep are proportionally increased.[2][3][4] As such, cinazepam produces a sleep state close to physiological, and for that reason, may be advantageous compared to other, related drugs in the treatment of insomnia and other sleep disorders.[2]

Cinazepam has an order of magnitude lower affinity for the benzodiazepine receptor of the GABAA complex relative to other well-known hypnotic benzodiazepines such as nitrazepam and phenazepam.[2] Moreover, in mice, it is rapidly metabolized, with only 5% of the base compound remaining within 30 minutes of administration.[2] As such, cinazepam is considered to be a benzodiazepine prodrug; specifically, to 3-hydroxyphenazepam, as the main active metabolite.[2]
