Eight schizophrenic patients received chlorpromazine and group psychotherapy, 8 received only chlorpromazine, and 7 patients acted as control. The two groups receiving the drug improved significantly more than the control in practically all measures. The 8 patients receiving group therapy in addition to the drug showed greater improvement than the drug-only group. Chlorpromazine is an effective adjunct to other therapies when used properly. It is not effective with all types of patients.
