Chlordiazepoxide

Chlordiazepoxide sold under the brand name Librium, is a sedative and hypnotic medication of the benzodiazepine class. It is used to treat anxiety, insomnia, and symptoms of withdrawal from alcohol, benzodiazepines, and other drugs. It is also used to discontinue long-term use of other, shorter-acting benzodiazepines due to its long half-life. Chlordiazepoxide has a medium to long half-life, while its active metabolite has a very long half-life. The drug has amnesic, anticonvulsant, anxiolytic, hypnotic, sedative, and skeletal muscle relaxant properties. Chlordiazepoxide was patented in 1958 and approved for medical use in 1960. It was the first benzodiazepine to be synthesized, and the discovery of chlordiazepoxide was by pure chance. 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.
