The psychopharmacology of GABA synapses: update 1989

Recent advances in the psychopharmacology of GABA synapses are reviewed. The usefulness of GABA mimetics in tardive dyskinesia and epilepsy has been confirmed, as has a dysfunction of GABA synapses in the etiopathology of these conditions. The antidepressant profile of GABA agonists in animal models for depression has been extended. The role of GABA receptors in the mechanism of action of antidepressants has been further delineated, with a parallelism occurring between the behavioral and biochemical response to antidepressant drug treatment in different animal models of depression.
