The antidepressant action is confirmed by the exacerbation of the schizophrenic psychosis in two patients who have received Tabex in a state of remission. The effect resembles the picture of the application of the antidepressant psychoforin of schizophrenic patients. These data are confirmed by Stoyanov and Yanachkova in psychic patients. These authors pointed out that the simple form of depression is appropriate for Tabex treatment with very careful increase of the daily doses.
