N2 - Available antipsychotics show different efficacy on manic symptoms of bipolar patients, but few studies have investigated the speed of action of the various compounds. For this reason, purpose of the present paper was to compare antipsychotic mono-therapies in terms of speed of action in a sample of manic bipolar patients. In total, 155 bipolar patients, treated with antipsychotic mono-therapy and followed-up in Inpatient Psychiatry Clinic of University of Milan, were included in this single-blind comparative study. Clinical response was defined as a reduction of Young Mania Rating Scale (YMRS) scores ⩾50%, while remission as a YMRS score <10. After 4 days patients who had been treated with asenapine, were more likely to have achieved a clinical response than those in treatment with haloperidol (p = 0.001). After 7 days, a more frequent clinical response was achieved by patients treated with asenapine than those who had been treated with haloperidol (p < 0.001) or olanzapine (p = 0.047). Asenapine appears to be faster in determining treatment response in manic patients compared with haloperidol and less markedly with olanzapine.
