The present invention concerns new derivatives of 1-aryl 2-aminomethyl cyclopropane carboxylates (Z), their preparation and their use as useful drugs for the treatment of various pains. The new derivatives of the present invention have the general formula I <IMAGE> (I) in which: R represents a hydrogen or halogen atom, a C1 to C4 lower alkyl group, a C1 to C4 lower alkoxy group, or a nitro, amino, sulfamoyl or hydroxy group; n represents the values 1, 2 or 3; (R)n may together with the benzene ring also form the naphthyl group; R1 represents a linear or branched C1 to C5 alkyl or alkenyl group or an aryl or benzyl group; R2 and R3 represent a hydrogen atom, a linear or branched C1 to C5 alkyl, alkenyl, alkynyl, hydroxyalkyl, alkoxyalkyl, carboxyalkyl or dialkylaminoalkyl group or an aryl, arylalkyl or cycloalkyl group; R2 and R3 possibly also forming a heterocycle of 5 or 6 members with the adjacent nitrogen atom, provided however that when R1 represents the ethyl radical and R represents a hydrogen atom, R2 and R3 cannot simultaneously represent a methyl radical.
