Effect of haloperidol and chlorpromazine on reversal learning of normal and striatectomized rats in a Y-maze. 1982

E B Arushanian, and V A Baturin

Haloperidol (0.05-0.1 mg/kg) and chlorpromazine (0.5-1.0 mg/kg) improved reversal learning avoidance responses in a Y-maze, decreased intersessional fluctuations of errors and decreased the number of spontaneous exits from a correctly selected chamber. After bilateral lesions of the striatum this effect disappeared. Brain lesions also attenuated the ability of neuroleptics to suppress amphetamine-induced stereotypy and and accompanying defects in avoidance responses. The improvement of avoidance behavior by neuroleptics may be related to the reduction of spatial preference caused by functional asymmetry between the bilateral nigro-striatal systems.

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.

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

D000661 Amphetamine A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
