Ergot derivatives have been proposed to have ameliorative effects in various pathological conditions where dopaminergic transmission is believed to be impaired, namely Parkinson's disease, amenorrhea-galactorrhea syndrome, and in the treatment of behavioural disturbances of the elderly. To get more insight into a possible involvement of a direct action of ergot derivatives on dopamine receptors we studied the effect of acute and chronic dihydroergotoxine (DHT) treatment on 3H-Spiroperidol and 3H-N-Propylnorapomorphine (3H-NPA) binding to rat striatal membrane preparations. The results are in favor of an interaction of ergot derivatives with dopamine recognition sites both after acute and chronic treatment.

Abstract
Ergot derivatives have been proposed to have ameliorative effects in various pathological conditions where dopaminergic transmission is believed to be impaired, namely Parkinson's disease, amenorrhea-galactorrhea syndrome, and in the treatment of behavioural disturbances of the elderly. To get more insight into a possible involvement of a direct action of ergot derivatives on dopamine receptors we studied the effect of acute and chronic dihydroergotoxine (DHT) treatment on 3H-Spiroperidol and 3H-N-Propylnorapomorphine (3H-NPA) binding to rat striatal membrane preparations. The results are in favor of an interaction of ergot derivatives with dopamine recognition sites both after acute and chronic treatment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
