Effects of penfluridol and other drugs on apomorphine-induced stereotyped behavior in monkeys. 1975

K Shintomi, and M Yamamura

The effects of some drugs on apomorphine-induced stereotyped behavior were studied in male cynomolgus monkeys. Apomorphine produced the dose-dependent stereotyped behavior characterized mainly by continuous licking and biting, and repetitive movements of the hands, head and body in the monkeys. Penfluridol as well as haloperidol showed a clear antagonistic effect on the apomorphine-induced stereotyped behavior, while chlorpromazine was less antagonistic than haloperidol. The antagonistic effect of penfluridol lasted longer than that of haloperidol. Reserpine did not inhibit the apomorphine-induced stereotyped behavior though the drug elicited markedly the behavioral depression and alpha-methyl-p-tyrosine also did not block the stereotyped behavior. Nialamide did not depress the apomorphine-induced stereotyped behavior. In provoking the stereotyped behavior in monkeys, apomorphine probably acts directly on dopamine receptors in the extrapyramidal system, and penfluridol is suggested to act as a dopamine receptor blocker with a long action. The results indicate that protection against apomorphine-induced stereotyped behavior in monkeys may be a useful method for evaluating neuroleptic drugs.

D010395	Penfluridol	One of the long-acting ANTIPSYCHOTIC AGENTS used for maintenance or long-term therapy of SCHIZOPHRENIA and other PSYCHOTIC DISORDERS.	R-16341,Semap,R 16341,R16341
D010880	Piperidines	A family of hexahydropyridines.
D012110	Reserpine	An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.

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.
