The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955, and was made available in 1960 by Hoffmann–La Roche, which followed with the development of diazepam (Valium) three years later, in 1963. [1] By 1977, benzodiazepines were the most prescribed medications globally; the introduction of ...
A book Good chemistry: The life and legacy of Valium inventor Leo Sternbach was published by McGraw-Hill in 2004.. Sternbach's uncle, Leon Sternbach, the brother of Sternbach's father Michael, was a professor of classical philology at Jagiellonian University.
It was the first benzodiazepine to be synthesized and the discovery of chlordiazepoxide was by pure chance. [6] Chlordiazepoxide and other benzodiazepines were initially accepted with widespread public approval, but were followed with widespread public disapproval and recommendations for more restrictive medical guidelines for its use.

[2] [3] Some of these designer drugs were originally synthesized by academic or industrial researchers in an effort to discover more potent derivatives with fewer side effects and shorter duration (and possibly also because it is easier to apply for patents for new molecules) and were later co-opted for recreational use.
Pliny the Elder, who lived from 23–79 CE, first gave a name to what we now call pills, calling them pilula. [2] Pliny also wrote Naturalis Historia a collection of 38 books and the first pharmacopoea. Pedanius Dioscorides wrote De Materia Medica (c. 40 – 90 CE); this book dominated the area of drug knowledge for some 1500 years until the ...
[69] [70] It is a 1,4 benzodiazepine, with the chemical name 1,3-Dihydro-7-nitro-5-phenyl-2H-1,4- benzodiazepin-2-one. It is long acting, lipophilic, and metabolised hepatically by oxidative pathways. It acts on benzodiazepine receptors in the brain which are associated with the GABA receptors, causing an enhanced binding of GABA to GABA A ...
Bromazepam is a "classical" benzodiazepine; other classical benzodiazepines include: diazepam, clonazepam, oxazepam, lorazepam, nitrazepam, flurazepam, and clorazepate. [16] Its molecular structure is composed of a diazepine connected to a benzene ring and a pyridine ring, the benzene ring having a single nitrogen atom that replaces one of the ...
Benzodiazepines require special precautions if used in the elderly, during pregnancy, in children, in alcoholics, or in other drug-dependent individuals and individuals with comorbid psychiatric disorders. [18] Triazolam belongs to the Pregnancy Category X of the FDA. [19] [1] It is known to have the potential to cause birth defects.
