Two grams of NAD were administered orally to ten chronic schizophrenic patients for twenty-one days. Five of the patients were also receiving thioridazine. There was no gross clinical improvement noted in any of the patients despite the fact that related experiments suggested that the NAD was absorbed. In those patients who were not also receiving phenothiazines there was a distinct tendency towards increased hostility, aggressiveness and irritability beginning one week after the initiation of NAD treatment and lasting for nearly two weeks after the NAD was discontinued.
