The invention concerns the use for making medicines with waking effect in conditions of disorders affecting wakefulness related to morphine treatment, of sulphinyl benzhydryl compounds of formula (I) in which: each of the cycles is substituted by one or several groups F, Cl, Br, CF3, NO2, NH2, C1-C4 alkyl, C1-C4 alkoxy, methylenedioxy; R is -OH, H, C1-C4 alkyl, C1-C4 hydroxyalkyl, or R1R2N-Y-, where Y is a hydrocarbon radical in C1-C4 with linear or branched chain; n is a whole number equal to 1, 2 or 3; and their additive salts when R comprises a basic radical. Said medicines enable to reduce sleepiness in patients without affecting the antalgic effect of morphine. |
