Barbiturates are a class of sedative-hypnotic drugs that depress the central nervous system and produce a wide range of effects, including sedation, relaxation, and sleep-induction. They are commonly prescribed to treat anxiety, insomnia, seizures, and as anesthetic agents. Examples of barbiturates include phenobarbital, pentobarbital, and secobarbital. However, barbiturates are known to have a high risk of abuse and dependence, and their use has declined due to the development of safer alternatives.
