Relating to or containing barbiturates, a class of chemical compounds used as sedatives and anesthetics.
From 'barbituric acid,' the parent compound of barbiturate drugs, named through a combination of 'barbiton' (possibly) and chemical naming conventions.
Barbituric acid is the chemical backbone of all barbiturate drugs—once chemists synthesized it, they could modify it slightly to create hundreds of different sedatives with different strengths and durations.
