Flutoprazepam

Flutoprazepam (Restas, KB-509) is a drug which is a benzodiazepine derivative. It was invented in Japan, and this is the main country in which it has been used medically. It has sedative, hypnotic, anxiolytic and anticonvulsant effects around 4 times more potent than those of diazepam, but is about the same potency as a muscle relaxant. It is however longer acting than diazepam due to producing long-acting active metabolites, which contribute significantly to its effects.

Flutoprazepam is used for the treatment of insomnia and anxiety, and also for treating stomach ulcers.
