Halazepam is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. It is a trifluoromethyl derivative of nordazepam.[1] 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.[2]
