  • Title: Proglumide, a cholecystokinin receptor antagonist, reduces neuroleptic action in Huntington's chorea.

    Journal: Eur Neurol; 1995; 35(6):344-8. PubMed ID: 8591802.
    Abstract:
    In a pilot study, proglumide, a cholecystokinin receptor antagonist, was administered to 8 patients affected from Huntington's chorea under long-term haloperidol treatment. The effectiveness of haloperidol on chronic symptomatology was reduced by the concomitant administration of proglumide; the latter drug, when administered alone, did not modify the severity of chorea compared to placebo. Possible explanations of these results are discussed, stressing the modulatory role of CCK not only on the dopaminergic, but also on the GABAergic system.
