Flunitrazepam, also known as Rohypnol among other names, is a benzodiazepine used to treat severe insomnia and assist with anesthesia. As with other hypnotics, flunitrazepam has been advised to be prescribed only for short-term use or by those with chronic insomnia on an occasional basis. It is said to be 10 times more potent than diazepam.
It was patented in 1962 and came into medical use in 1974. Flunitrazepam has been referred to as a date rape drug, though the percentage of reported rape cases in which it is involved is small
Rohypnol 1 mg tablets.
In countries where this drug is used, it is used for treatment of severe cases of sleeping problems, and in some countries as a preanesthetic agent. These were also the uses for which it was originally studied.
It has also been administered as a concurrent dose for patients that are taking ketamines. Rohypnol lowers the side effects of the anesthetic (ketamine): less confusion in awakening states, less negative influence on pulse rate, and fewer fluctuations in blood pressure.
It has also been shown to have therapeutic use in polydrug abuse when combined with anesthetics, opioids, ethanol, cocaine, and methamphetamine.
