Flunitrazepam

Flunitrazepam ( /ˌfluːnɨˈtræzɨpæm/) (Also known as: Narcozep, Rohypnol, Primun, Rohipnol, Roipnol) is an intermediate acting benzodiazepine used as hypnotic, sedative, anticonvulsant, anxiolytic and skeletal muscle relaxant drug.

In general, the prescription of flunitrazepam as a hypnotic is intended to be for short-term treatment of chronic or severe insomniacs not responsive to other hypnotics, especially in inpatients. It is considered to be one of the most effective benzodiazepine hypnotics on a dose basis. Just as with other hypnotics, flunitrazepam should be used only on a short-term basis or in those with chronic insomnia on an occasional basis.

Flunitrazepam is classed as a nitro-benzodiazepine. It is the fluorinated methylamino derivative of nitrazepam. Other nitro-benzodiazepines include nitrazepam — the parent compound — and clonazepam, the chlorinated derivative.

Though flunitrazepam have been referred to as date rape drug because of its high potency, strong effects and the ability to cause strong amnesia during its duration of action, Robertson's study indicated that flunitrazepam was used in only around 1% of reported date rapes and 0.33% according to urine lab tests done by El Sohly.
