<unk>  is a GABA receptor agonist. It has two stereoisomers, and shows stereoselectivity in its actions. Specifically, (R)-(–)-GABOB is a moderate-potency agonist of the<unk>  receptor, while (S)-(+)-GABOB is a partial agonist of the<unk>  receptor and an agonist of the GABAA receptor. (S)-(+)-GABOB is around twice as potent an anticonvulsant as (R)-(–)-GABOB.<unk>  is used medically as a racemic mixture. Relative to GABA,<unk>  has more potent inhibitory effects on the central nervous system, perhaps due to its greater capacity to cross the blood–brain barrier. However,<unk>  is of relatively low potency as an anticonvulsant when used by itself, and is more useful as an adjuvant treatment used alongside another anticonvulsant.
