Zusammenfassung:4,5,6,7-Tetrahydrobenzimidazole derivatives (I) and salts thereof show 5-HT3 antagonizing activity wherein R , R , R independently represent hydrogen atom, hydroxy group, a halogen atom, a lower alkyl group which may optionally be substituted with a halogen atom, a lower alkoxy group, a lower alkylthio group, an aralkyloxy group, an aryloxy group, a lower alkanoyl group, carboxy group, a lower alkoxycarbonyl group or nitro group; R ,R and R can each be a hydrogen atom or a lower alkyl group; and X is an oxygen atom or sulfur atom. d
