Being one of the first types of benzodiazepines discovered in the world, Diazepam helped to produce other drugs, including Tofisopam, Lorazepam, Alprazolam.

Diazepam is listed as an essential medicine by the World Health Organization due to its high importance. While Diazepam is not too potent, its effect is long-lasting. The low toxicity of Diazepam allows it being prescribed and taken for several years in a row; however, Diazepam can lead to a strong psychological dependence.

Diazepam can treat neurosis, schizophrenia, sleep disturbances, personality disorders, brain damage, and emotional stress.
