Clinical Significance: In Latin America and Europe, Rohypnol (Flunitrazepam) is prescribed as a short-term treatment for insomnia, and as preanesthetic medication. Flunitrazepam is considered a drug of abuse when used to enhance the effect of other substances such as marijuana, heroin, and ethanol. The combination of ethanol and flunitrazepam may lead to sedation, loss of motor function, impaired judgement, behavioral changes, and anterograde amnesia.
