<unk>  /ˌfluːn[invalid input: 'ɨ']ˈtræz[invalid input: 'ɨ']pæm/ — also known as Narcozep, Rohypnol, Rohipnol, Roipnol, Rufies or  Roofies — is an intermediate acting benzodiazepine used as an hypnotic, sedative, anticonvulsant, anxiolytic, and skeletal muscle relaxant drug.
It was developed by a team led by Leo Sternbach at Hoffman La-Roche and produced from common precursors to 1,4-benzophenones, in 1963. A series of tests showed that an N-methyl & '2F-fluoro produced the most potent hypnotic of the series that started with an earlier Sternbach invention, nitrazepam.
In general, the prescription of<unk>  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,<unk>  should be strictly used only on a short-term basis or in those with chronic insomnia on an occasional basis.<unk>  is classed as a nitro-benzodiazepine. It is the fluorinated N-methyl derivative of nitrazepam. Other nitro-benzodiazepines include nitrazepam (the parent compound), nimetazepam (methylamino derivative) and clonazepam (the chlorinated derivative).<unk>  has been referred to as a date rape drug because of its high potency and ability to cause strong amnesia. However, Robertson's study (in the 1990s) indicated that<unk>  was used in only around 1% of reported date rapes and 0.33% according to urine lab tests done (before 2001) by El Sohly.
