MedKoo CAT#: 317504

CAS#: 58-25-3

Description: Chlordiazepoxide is a sedative/hypnotic drug and benzodiazepine. Chlordiazepoxide 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. Chlordiazepoxide has a medium to long half-life but its active metabolite has a very long half-life. The drug has amnestic, anticonvulsant, anxiolytic, hypnotic and skeletal muscle relaxant properties. Chlordiazepoxide is discontinued.
