Primary outcome measures were changes in the Positive and Negative Syndrome Scale (PANSS) total score and the incidence of withdrawal due to adverse effects. Eight randomized clinical trials, encompassing 3765 patients, that compared asenapine with placebo ( n = 5) and olanzapine ( n = 3) were included. No differences were found between asenapine and olanzapine in terms of changes to PANSS total or PANSS negative subscale scores. Patients taking asenapine were more likely to experience worsening schizophrenia and/or psychosis than were those taking olanzapine. No differences were found between asenapine and olanzapine in rates of discontinuation due to adverse drug reactions or lack of efficacy, but those taking asenapine had higher rates of withdrawal for any reason than those taking olanzapine. Asenapine caused less clinically significant weight gain or increases ...Continue Reading
