Tetrahydroisoxazolopyridinol (THIP), a GABA receptor agonist, gamma-acetylenic-GABA(GAG) and gamma-vinyl-GABA(GVG), two GABA transaminase inhibitors were given in single parenteral doses to three Cebus apella monkeys with persistent dyskinetic movements induced by earlier long-term administration of haloperidol. High doses of THIP temporarily abolished dyskinesias but also caused bradykinesia, ataxia, dystonia and myoclonic jerks. GAG and GVG reduced dyskinesias to a lesser extent and with fewer side effects. Whether the observed antidyskinetic effect is secondary to the concomitant general toxic effects or if these drugs have a specific antidyskinetic action remains an open question.
