Introduction

Nitemazepam (or 3-hydroxynimetazepam) is a benzodiazepine derivative which was first synthesised in the 1970s but was never marketed.

It is the 7-nitro instead of 7-chloro analogue of temazepam, and also the 3-hydroxy derivative of nimetazepam, and an active metabolite.

It has in more recent years been sold as a designer drug, first being definitively identified in Europe in 2017.

Not to be confused with Nimetazepam or Nitrazepam.
