German scientists isolated barbituric acid - a substance that will be the basis of sleeping pills and registered the first drug patent that will become a hope for those with insomnia on July 9, 1902.
Called Veronal, it was produced in 1904 by German companies Merck and Bayer as a sleeping pill, thanks to the work of german chemist Emil Fischer (Nobel Prize in Chemistry, 1902) and his collaborator Josef von Mering. Veronal had hypnotic, sedative, and anticonvulsant properties. It could calm manic patients and help melancholic patients to sleep, and was an effective inducer of sleep in insomniacs.
The most significant results were obtained in the treatment of patients with serious neuroses and psychoses and with severe emotional repression, who as a result of being administered barbiturates, especially intravenously, overcame their inhibitions, thus facilitating psychotherapeutic treatment.
