Halazepam
Halazepam is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. It is a trifluoromethyl derivative of nordazepam. While its structure may be similar to chlordiazepoxide and diazepam, it has both less toxicity and less tendency to cause paradoxical hostility and aggression than either of them. Halazepam is no longer marketed in the United States, and was withdrawn by Schering-Plough due to poor sales. [Wikipedia]
