The barbiturate is a molecule derived from barbituric acid, whose principal uses in medicine are designed to anesthetize the body, either gently or deeply. Barbiturates have a sedative effect, meaning they decrease the activity of the central nervous system. At low doses, they are tranquilizers, and in large doses, they are used in general anesthesia for surgical operations. Because of their significant side effects and the risk of addiction, their use is limited. The abuse of barbiturates can lead to a state of dependency and death.
