barbiturate

any of a group of organic compounds derived from barbituric acid. There are a number of barbiturates. They all depress the nervous system and are used to induce apathy and sleep, and in high doses, as anesthetics. They vary in their sedative effects, in the duration of their effectiveness and in their toxicity. Those that are used in veterinary medicine are: (1) pentobarbital sodium (Nembutal); largely superseded, but still sometimes used for intravenous anesthesia in companion animals; (2) thiopental sodium, which has a short period of effectiveness, an advantage in many veterinary situations, e.g. examination of a pharynx; (3) thialbarbital sodium, a medium length compound; (4) thiamylal sodium, a compound with ultrashort action.
