ABSTRACT:
The present invention relates to novel monohydrochloride, dihydrochloride, monohydrobromide, maleate and methanesulphonate salts of trans 4-{2-[4-(2,3-dichlorophenyl)-piperazine-1-yl]-ethyl}-N,N-dimethylcarbamoyl-cyclohexylamine and/or their hydrates and/or solvates. Moreover, the invention relates to the process for preparing the salts and their hydrates and/or solvates, to their use in the treatment and/or prevention of conditions which require modulation of dopamine receptor and to pharmaceutical compositions containing them.
