Sertindole appears effective as an antipsychotic in schizophrenia.[4] In a 2013 study in a comparison of 15 antipsychotic drugs in effectivity in treating schizophrenic symptoms, sertindole was found to be slightly less effective than haloperidol, quetiapine, and aripiprazole, as effective as ziprasidone, approximatly as effective as chlorpromazine and asenapine, and slightly more effective than lurasidone and iloperidone
