The wide scale use of expensive atypical antipsychotic medications has led to a dramatic increase in the proportion of direct costs schizophrenia being allocated for medications. Although there is evidence that the atypical antipsychotic, clozapine, may lead to cost savings in patients with refractory schizophrenia the cost-effectiveness of the other atypical antipsychotics remains in question. We therefore reviewed the published, long-term randomized, prospective cost-effectiveness treatment studies that compared an atypical to a typical antipsychotic. There were serious methodological problems with all. In general, those that were based on efficacy trials showed an advantage for atypicals while those based on effectiveness studies found the opposite. It appears that to the extent that studies mimic "real world" conditions they fail to support the cost-effectiveness of the atypical antipsychotics.
