Effects of trifluoperazine, chlorpromazine, and haloperidol upon temporal information processing by schizophrenic patients. 1979

S Goldstone, and H G Nurnberg, and W T Lhamon

Healthy controls, unmedicated, actively symptomatic schizophrenics, and similar patients undergoing treatment with either trifluoperazine, chlorpromazine, or haloperidol were studied with tests of temporal discrimination and measures of transmitted information shown previously to be sensitive to various kinds of brain dysfunction, including haloperidol effects in a nonpsychotic population. Variations in psychophysical method, cognitive load, discrimination complexity, and sense-mode conditions permitted representative sampling of the temporal processing. Untreated, actively psychotic patients showed no impairment of temporal processing while all three antipsychotic medications were associated with significant deficit; trifluoperazine and haloperidol produced the most deficit, with chlorpromazine in the middle between the higher potency drugs on the one hand and unmedicated patients and healthy controls on the other.

UI	MeSH Term	Description	Entries
D002746	Chlorpromazine	The prototypical phenothiazine antipsychotic drug. Like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking DOPAMINE RECEPTORS. Chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup.

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
