Chlorpromazine alone and with reserpine; use in the treatment of mental diseases.

One hundred psychiatric patients were treated with chlorpromazine, alone or combined with reserpine. Fifty-six per cent of patients with chronic schizophrenic reactions showed moderate or pronounced improvement when treated with chlorpromazine alone. The results of treatment with the combined drugs were not so good as that. Indications are that treatment of patients with chronic schizophrenic reactions is more efficacious with these drugs than with other forms of somatic therapy. Complications of treatment were far greater with combined use of chlorpromazine and reserpine. For this reason, the combination appears to have limited usefulness. The Parkinson syndrome was the most frequent complication of large doses of these drugs. It appears to be a toxic reaction, requiring reduction in dosage. Jaundice appears to be neither a frequent nor a serious complication of treatment.
