N,N-bis(3-aminopropyl)cyclohexane-1,4-diamine, of formula (I), is a new compound that is prepared by hydrogenation with Raney nickel catalyst of N,N-bis(2-cyanoethyl)-cyclohexane-1,4-diamine, the latter being prepared by reaction between 1,4-cyclohexanediamine and acrylonitrile. The oral administration to genetically alcoholic rats (from the strain UChB of the University of Chile) of the tetrametanesulfonate monohydrate of (I) causes a significant reduction in the alcohol consumption. The activity lasts for some time after the treatment period. Besides, there is a virtually null disulfiram-like adverse effect, what constitutes an advantage over the unpleasant use of some anti-alcoholism agents, such as calcium cyanamide or disulfiram itself. Therefore, the compounds of the invention are useful for the preparation of medicaments for the therapeutic and/or prophylactic treatment of alcoholism in mammals, including human beings ##STR1##
