Abstract
The invention relates to thiadiazole derivatives corresponding to the formula: ##STR1## in which R represents: a linear or branched alkyl group having from 1 to 5 carbon atoms; PA1 a cycloalkyl group having 5 or 6 carbon atoms; PA1 a phenyl group optionally substituted by 1 or 2 halogen atoms, preferably chlorine, by 1 or 2 lower alkyl or lower alkoxy groups, by 1 or 2 hydroxyl groups or by a nitro or trifluoromethyl group; PA1 a biphenylyl group; or PA1 an alpha-naphthyl group; and the pharmaceutically acceptable salts of the said derivatives. It also relates to a process for the preparation of the said derivatives and the pharmaceutical compositions in which they are present. The said derivatives act on the central nervous system.
