Flunitrazepam
Flunitrazepam (formerly marketed under the trade name Rohypnol in the United States) is a drug which is a benzodiazepine derivative. It has powerful sedative, anxiolytic, and skeletal muscle relaxant properties. more...
History
Flunitrazepam was first synthesized in the early 1970s by Roche and was used in hospitals when deep sedation was needed. It first entered the commercial market in Europe in 1975, and in the 1980s it began to be available in other countries.
It originally came in 1mg, 2mg, and 5mg sizes, but due to its potency and potential for abuse, the higher doses were taken off the market and it is now only available in 1mg.
Pharmacology
Like other benzodiazepines, flunitrazepam's pharmacological effects include sedation, muscle relaxation, reduction in anxiety, and prevention of convulsions. However, flunitrazepam's sedative effects are approximately 7 to 10 times more potent than diazepam. The effects of flunitrazepam appear approximately 15 to 20 minutes after oral administration, and last for approximately four to six hours. Some residual effects can persist up to 12 hours or more after administration.
Medical Uses
Flunitrazepam has not been approved by the Food and Drug Administration for medical use in the United States.
Illegal Uses
Use as a date rape drug
Flunitrazepam is known to induce anterograde amnesia in sufficient doses; individuals are unable to remember certain events that they experienced while under the influence of the drug. This effect is particularly dangerous when flunitrazepam is used to aid in the commission of sexual assault; victims may not be able to clearly recall the assault, the assailant, or the events surrounding the assault.
It is difficult to estimate just how many flunitrazepam-facilitated rapes have occurred in the United States. Very often, biological samples are taken from the victim at a time when the effects of the drug have already passed and only residual amounts remain in the body fluids. These residual amounts are difficult, and sometimes impossible, to detect using standard screening assays available in the United States. If flunitrazepam exposure is to be detected at all, urine samples need to be collected within 72 hours and subjected to sensitive analytical tests. The problem is compounded by the onset of amnesia after ingestion of the drug, which causes the victim to be uncertain about the facts surrounding the rape. This uncertainty may lead to critical delays or even reluctance to report the rape and provide appropriate biological samples for testing. If a person suspects that he or she is the victim of a flunitrazepam-facilitated rape, he or she should get laboratory testing for flunitrazepam as soon as possible.
It must be noted that an inability to remember events, including sexual encounters, is not conclusive evidence of having consumed a drugged drink: Drunkenness itself causes blackouts, sleepiness, and a reduction in inhibitions. Only a timely screening for flunitrazepam can demonstrate its use.
