Abstract
Schizophrenic patients resistant to antipsychotics are diagnosed as having treatment-refractory schizophrenia, and they are treated with clozapine. However, clozapine is sometimes combined with electroconvulsive therapy (ECT) if clozapine monotherapy fails. In this report, a severe treatment-refractory schizophrenic patient who did not respond to clozapine even with ECT, but who recovered with asenapine monotherapy, is presented. Asenapine, considered a serotonin spectrum dopamine modulator, is a new atypical antipsychotic with unique pharmacological features that is used not only for schizophrenia, but also for bipolar disorder. The unique features of asenapine may be effective for some treatment-refractory schizophrenic patients.
