Talbutal

Talbutal is a barbiturate drug. It is classified as a short- to intermediate-acting barbiturate. While it once saw use as a sedative and hypnotic, its use has largely been superseded by benzodiazepines due to the latter's comparatively safer profile and lower risk of overdose. Barbiturates, including talbutal, act as central nervous system depressants, primarily by enhancing the effects of GABA (gamma-aminobutyric acid), a major inhibitory neurotransmitter in the brain. Overdose can lead to respiratory depression, coma, and death. Talbutal is a controlled substance in many jurisdictions, reflecting its potential for abuse and dependence. Its chemical structure contains a barbituric acid ring with specific substitutions that determine its pharmacological properties and duration of action.
