[Psychopharmacology and psychiatric aspects of pain].

The psychological and psychopathological aspects of pain serve to emphasize the therapeutic importance of psychopharmacological drugs in the treatment of this frequent symptom. Using the classification of psychotropic drugs made by Delay and Deniker, the author analyses the practical applications of some psycholeptics, some psychoanaleptics, and even some psychodysleptics in anti-pain therapeutics. The analysis of some statistics on the frequency of pain in different patient samples, from general medicine as well as from psychiatry, helps to comment upon the great advance implied by the psychopharmacological revolution.
