title: Comparison of efficacy of zotepine and thiothixene in schizophrenia in a double-blind study.
abstract: Zotepine and thiothixene were compared for clinical efficacy and safety in a double-blind trial. Using overall improvement ratings and Gorham's BPRS, zotepine rated higher improvement in motor retardation, suspiciousness, mannerisms and posturing symptoms, suggesting that it has both activating and antipsychotic activities. Thiothixene produced higher improvement ratings in symptoms such as hallucinatory behavior, somatic concerns, anxiety, guilt feelings, tension, depressive mood and uncooperativeness. As for side effects, there was a significantly lower frequency of dry mouth and insomnia with zotepine when compared with thiothixene. The lower incidence of insomnia is interesting in view of zotepine's clinical activating effects. There were no abnormal laboratory findings.
