Barbiturates are a type of medication that slows down the central nervous system. They are mainly used to help people sleep, calm anxiety, and sometimes prevent seizures. Barbiturates work by increasing the effects of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which has a calming effect on the nervous system. These medications are prescribed by healthcare providers for short-term management of conditions such as insomnia, anxiety disorders, and certain types of epilepsy. However, because of their potential for overdose and addiction, barbiturates are now less commonly prescribed and have been replaced by safer options like benzodiazepines.
