A barbiturate that is administered intravenously for the induction of general anaesthesia or for the production of complete anaesthesia of short duration. It is also used for hypnosis and for the control of convulsive states. It has been used in neurosurgical patients to reduce increased intracranial pressure. It does not produce any excitation but has poor analgesic and muscle relaxant properties. Small doses have been shown to be anti-analgesic and lower the pain threshold.
Pharmacological action: anaesthetics, intravenous, anticonvulsants, gaba modulators, sedatives, barbiturate.
