[Pharmacologic effect of protracted neuroleptics, fluphenazine oenanthate and oxyprothepine oenanthate (VUFB 9447)]

Two neuroleptica with protracted effect, i.e. Fluphenazin-Oenanthat and Oxyprothepin-Oenanthat, were tested on rats, dogs and rabbits. It was found that both drugs, after intramuscular injection in doses between 5--30 mg/kg, produced a long-lasting neuroleptic effect, in particular the inhibition of conditioned reflexes in rats, the antagonistic effect against apomorphine vomiting in dogs and the EEG-brain activity specific for neuroleptica. Hardly any differences were found between the effects of the two drugs. Both neuroleptica caused interesting spike activity in the EEG-registration particularly in the limbic structures which have hitherto not been described in the literature.
