title: Influence of the histaminergic system on opiate-induced neurosecretion and behaviour.
abstract: The influence of the histaminergic system on fentanyl (Fe)-induced growth hormone (GH) and prolactin (PRL) release as well as on Fe-induced increase of noradrenaline (NA) plasma levels has been studied in male volunteers. These volunteers received, according to a randomized block design, different pretreatments: the H1-antagonist dimethindene (Di) (0.1 mg/kg i.v.), or the H2-antagonist cimetidine (Ci)(5 mg/kg i.v.), or a combination of dimethindene and cimetidine (Di + Ci), or saline. The PRL increase caused by Fe (0.2 mg/70 kg) was not altered by pretreatment with the H1-antagonist Di, the H2-antagonist Ci, or the combination of both. The increase of NA plasma levels after Fe also was not modified by the histamine antagonists. In contrast, the maximum GH increase after Fe was blunted by the combination of Ci and Di, but not by either Ci or Di alone. These results suggest an involvement of the histaminergic system in opiate-induced GH-release.
