RT Journal A1 Tamminga CA, Crayton JW, Chase TN T1 IMprovement in tardive dyskinesia after muscimol therapy JF Archives of General Psychiatry JO Archives of General Psychiatry YR 1979 FD May 1 VO 36 IS 5 SP 595 OP 598 DO 10.1001/archpsyc.1979.01780050105013 UL http://dx.doi.org/10.1001/archpsyc.1979.01780050105013 AB • Muscimol, thought to be a agonist of γ-aminobutyric acid (GABA), was administered to eight neuroleptic-free subjects with tardive dyskinesia. At oral dose levels from 5 to 9 mg, involuntary movements were consistently attenuated, usually in the absence of sedation. These results support the view that pharmacologic attempts to stimulate GABA-mediated synaptic transmission may afford symptomatic relief to patients with tardive dyskinesia.
