This invention pertains to a method for treating a condition of nausea and vomiting in a mammal which comprises administering a therapeutically effective amount of a 4,5,6,7-tetrahydroimidazo[4,5-c]pyridinyl-6-carboxylic acid derivative represented by the formula: <IMAGE> (1) wherein R1 and R2 are hydrogen or lower-alkyl; R3 is selected from the group consisting of hydrogen, lower-alkyl, nitro, amino, cyano, and alkylmercapto; R4 and R5 are selected from the group consisting of hydrogen, lower-alkyl, aryl, and aryl lower-alkyl, or R4 and R5 together with the carbon atom to which they are attached form a 5- or 6-member saturated hydrocarbon ring; R6 is selected from the group consisting of hydrogen, lower-alkyl, aryl lower-alkyl, formyl, lower-alkyl carbonyl, and aryl carbonyl; R7 is selected from the group consisting of phenyl, thienyl, indolyl, indazolyl, benzo[b]furanyl, benzo[b]thiophenyl, and R8R9-N-; R8 is selected from the group consisting of 8-[1,2,3,4,-tetrahydroquinolinyl], pyridinyl, 3-quinolinyl, 2-naphthalinyl, 2-thiazolyl, 2-benzothiazolyl, 4-[2,1,3]benzothiadiazolyl, 2-(4,5,6,7-tetrahydrobenzo)thiazolyl, 7-(2,2-dimethyl-2,3-dihydrobenzo)furanyl, and phenyl; R9 is hydrogen or lower-alkyl; R8R9-N- is selected from the group consisting of 1-indolinyl, 1-(3,3-dimethylindolinyl), and 1-(1,2,3,4-tetrahydroquinolinyl); wherein the groups represented by R7 other than R8R9N- may be unsubstituted or substituted with one or more substituents selected from the group consisting of lower-alkyl, lower-alkoxy, di-lower-alkylamino, and aryloxy, and the groups represented by R8 and the radical R8R9N- may have one or more substituents selected from the group consisting of hydroxy, halogen, lower-alkyl, lower-alkoxy, amino, mono- or di-lower-alkylamino, lower-alkyl carbonyl, lower-alkoxy carbonyl, and aryloxy; wherein each aryloxy group may be unsubstituted or substituted with substituents independently selected from the group consisting of lower-alkyl, lower-alkoxy, halogen, and trifluoromethyl with the proviso that, when R8 is phenyl, said phenyl group contains at least one substituent.
