Benzodiazepines are widely used in medicine to treat anxiety and insomnia. These are synthetic substances normally seen as pharmaceutically-manufactured tablets, capsules and occasionally as injectables. They act as depressants of the central nervous system (CNS). Chlordiazepoxide (Librium®) was the first to be synthesised in 1957 and introduced into medicine in the 1960s. Benzodiazepines are regularly used in medicines for anxiety suppression, sedation, muscle relaxation, disinhibition, sleepiness and amnesia. In a medical context, short-acting benzodiazepines are typically recommended for treating insomnia or acute panic attacks while long-acting ones are recommended for the treatment of anxiety disorders.
