The effects of dopamine D-1 and D-2 receptor agonists were evaluated in five Cebus apella monkeys. During a previous haloperidol treatment (2 years), three of the monkeys had developed oral tardive dyskinesia (tongue protrusion and/or chewing). The partial D-1 agonist, SKF 38393, induced/aggravated oral dyskinesia and slight sedation, but no non-oral repetitive movements. Conversely, the selective D-2 agonist, LY 171555, produced non-oral repetitive movements and increased reactivity (arousal), but no significant change in the oral movements. Apomorphine (a mixed D-1/D-2 agonist) induced non-oral repetitive movements, increased reactivity, and increased oral dyskinesia. Pretreatment with SKF 38393 inhibited the LY 171555-induced non-oral repetitive movements, while in four monkeys the SKF 38393-induced oral movements were inhibited by LY 171555. The results suggest that oral dyskinesia (tardive dyskinesia) is more related to D-1 receptor stimulation than to D-2 receptor supersensitivity.

D004409	Dyskinesia, Drug-Induced	Abnormal movements, including HYPERKINESIS; HYPOKINESIA; TREMOR; and DYSTONIA, associated with the use of certain medications or drugs. Muscles of the face, trunk, neck, and extremities are most commonly affected. Tardive dyskinesia refers to abnormal hyperkinetic movements of the muscles of the face, tongue, and neck associated with the use of neuroleptic agents (see ANTIPSYCHOTIC AGENTS).

D006220	Haloperidol	A phenyl-piperidinyl-butyrophenone that is used primarily to treat SCHIZOPHRENIA and other PSYCHOSES. It is also used in schizoaffective disorder, DELUSIONAL DISORDERS, ballism, and TOURETTE SYNDROME (a drug of choice) and occasionally as adjunctive therapy in INTELLECTUAL DISABILITY and the chorea of HUNTINGTON DISEASE. It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)	Haldol
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001058	Apomorphine	A derivative of morphine that is a dopamine D2 agonist. It is a powerful emetic and has been used for that effect in acute poisoning. It has also been used in the diagnosis and treatment of parkinsonism, but its adverse effects limit its use.
