Compounds of formula (I), or a salt or prodrug thereof, wherein R represent hydrogen or C.sub.1-6 alkyl; Q represents a moiety of formula Qa or Qb; they are antagonists of dopamine receptor subtypes within the brain, having a selective affinity for the dopamine D.sub.4 receptor subtype over other dopamine receptor subtypes, and are accordingly of benefit in the treatment and/or prevention of psychotic disorders such as schizophrenia whilst manifesting fewer side-effects than those associated with classical neuroleptic drugs. ##STR1##
(EN) A class of chemical compounds comprising a benzimidazole moiety and a substituted heterocyclic moiety, linked via the 3-position of the benzimidazole moiety by a methylene group, are ligands for dopamine receptor subtypes within the body and are therefore useful in the treatment and/or prevention of disorders of the dopamine system, in particular schizophrenia.(FR) Classe de composés chimiques comportant une fraction benzimidazolique et une fraction hétérocyclique substituée, liées en position 3 de la fraction benzimidazolique par un groupe méthylène. Ces composés sont des ligands pour les sous-types récepteurs de dopamine dans l'organisme. Par conséquent, ils sont utilisables dans le traitement et/ou la prophylaxie des troubles du système dopamine, notamment la schizophrénie.
