[The importance of psychotropic drugs for gerontology].

Psychopharmacotherapy in the aged with psychiatric problems must always be considered within the framework of an overall therapeutic concept. In the elderly, psychotropic drugs are prescribed for the same sort of symptoms as those observed in young adults. The multimorbidity often observed in old age can lead to a polypragmatic approach with associated possible interactions between the various drugs, and possible potentiation of known side effects. The side effects are frequently misunderstood and additional drugs prescribed, or doses increased, sometimes with development of confusion that might lead to unnecessary hospitalization. An accurate diagnosis, selection of the smallest possible dosage, and prescription only when the indication has been clearly established, should be our guidelines when prescribing such drugs in the elderly.
