Abstract: The invention relates to substituted arylamines and heteroarylamines, their preparation process and the pharmaceutical composition containing them. Said substituted amine is in accordance with the formula: ##STR1## in which R.sup.1 and R.sup.2 are optionally substituted alkyl radicals or form with N an optionally substituted piperazine or piperidine cycle, R.sup.3 and R.sup.4 represent a hydrogen atom or an organic radical, Y represents CR.sup.6 or N and R.sup.5 is an optionally substituted benzothiophenyl, benzofuranyl or naphthyl radical.These amines can be used in pharmaceutical compositions for the treatment of nervous depression or for stimulating vigilance.

Abstract: The invention relates to pharmaceutical compositions for neuroprotection containing arylcyclohexylamines. These compositions comprise an arylcyclohexylamine in accordance with the formulas: ##STR1## in which: R.sup.1 represents ##STR2## with R.sup.4 being a hydrogen atom, a fluorine atom, an iodine atom or a methyl radical, R.sup.2 stands for a hydrogen atom, the radical OH or the radical CH.sub.3 and R.sup.3 stands for hydrogen atom or the radical CH.sub.2 R.sup.5 with R.sup.5 representing H, OH, Cl, Br or CH.sub.3 COO, provided that R.sup.2 and R.sup.3 are not both a hydrogen atom, or an addition salt to a pharmaceutically acceptable acid of said arylcyclohexylamine.
