I.OVERVIEW
A.Introduction
The past 5 years have witnessed a dramatic shift in the pharmacotherapy of adult schizophrenia. Following on the therapeutic success of clozapine in patients with treatment-refractory schizophrenia, there are now several agents available in the United States as first-line choices in the treatment of schizophrenia (Table 1). The evidence for superior efficacy of these agents over typical antipsychotics is substantial and continues to accrue (1). The evidence for a more favorable adverse-effect profile, especially with respect to extrapyramidal side effects (EPS) and tardive dyskinesia (TD), is compelling. Collectively, these data have supported a shift in clinical practice wherein most clinicians in the United States are prescribing atypical antipsychotics as the first-choice agents for new-onset schizophrenia as a maintenance therapy. The preferential role for typical antipsychotics remains in the management of acute agitation in

psychosis-by the use of acute intramuscular preparations-and in the management of patients who are persistently noncompliant with medication-by the use of long-acting (depot) injections. The coming on-line of both short-acting and depot forms of atypical antipsychotic medication is likely to further diminish the role of typical antipsychotics in clinical practice (2-4). The pace of this shift in treatment patterns and the ultimate equipoise between atypical and typical antipsychotic medications remains to be determined (5,6).
