Nicotinic acid as adjuvant therapy in newly admitted schizophrenic patients.

A placebo-controlled, comparative clinical study was conducted to test the hypothesis that nicotinic acid as an adjuvant medication has a beneficial therapeutic effect over and above the effect which can be achieved by the administration of phenothiazine drugs alone, over a six-month period, in newly (recently) admitted schizophrenic patients.The most important single finding was that no statistically significant therapeutic difference was seen between the active treatment and the placebo groups; i.e., the addition of nicotinic acid or nicotinamide to the regular phenothiazine treatment regimen did not have any measurable therapeutic effect in this sample of patients. It was shown that patients in the placebo group received a lower total daily amount of phenothiazine drugs than those on either of the active substances. Furthermore, it was noted that the addition of the active substances did not reduce the number of days of hospitalization.
