12
Options for Antipsychotic Therapies Prior to Antipsychotics Conventional or Typical Antipsychotics (First Generation) Atypical Antipsychotics (Second Generation) 19521980s2000s Chlorpromazine Haloperidol Fluphenazine Thioridazine Loxapine Perphenazine Trifluoperazine Thiothixene Molindone Clozapine Aripiprazole Paliperidone Iloperidone Asenapine Lurasidone 1960s1990s Risperidone Olanzapine Quetiapine Ziprasidone
13
Antipsychotic Practice Major changes in antipsychotic practice over the past decade. New, atypical antipsychotics now comprise vast majority of antipsychotic prescriptions –considered more effective than typical antipsychotics –thought to have fewer side-effects –much more costly than typicals
14
Questions about Utility of Atypical Agents Relative utility of the atypicals has recently been questioned: – Are they really more effective? – Are their side-effects (eg., obesity, diabetes) not a significant concern? – Are they all essentially similar? Before the Typical-Atypical Controversy: –WHAT MATTERS –EFFICACY versus TOLERABILITY
15
EFFICACY vs. TOLERABILITY: WHICH TRUMPS? POINT- COUNTERPOINT DEBATE WHERE DO YOU STAND?Efficacy Side effects
16
POINT-COUNTERPOINT LET THE DEBATE BEGIN……

EFFICACY vs. TOLERABILITY: WHICH TRUMPS? FGA’S ARE EQUIVALENT IN EFFICACY TO SGA’S EFFICACY IS SIMILAR ACROSS ALL SGA’S EFFICACY MATTERS MORE THAN SIDE EFFECTS IN FIRST EPISODE SCHIZOPHRENIA EPS/TD WEIGHT GAIN/HYPERLIPIDEMIA/HYPERGLYCEMIA HYPERPROLACTINEMIA/SEXUAL DYSFUNCTION ANTICHOLINERGIC/DRY MOUTH/CONSTIPATION SOMNOLENCE/SEDATION
18
HOW DO WE KNOW? EVIDENCE-BASED MEDICINE Preponderance of data about antipsychotic effectiveness in schizophrenia – Large-scale clinical trials – Meta-analyses
19
Series of Effectiveness Studies Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) - USA Cost Utility of the Latest Antipsychotics in Severe Schizophrenia (CUtLASS) - UK Treatment of Early-Onset Schizophrenia (TEOSS) - USA European Union First Episode Schizophrenia Trial (EUFEST) - Europe

CATIE-Schizophrenia Trial: All- Cause Discontinuation Time to discontinuation for any cause (mo) Lieberman JA et al. N Engl J Med. 2005;353:1209-1223. Olanzapine (n=330) Perphenazine (n=257) Risperidone (n=333) Quetiapine (n=329) Ziprasidone (n=183) 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 1.0 0369121518 Proportion of patients without event

Second-Generation Antipsychotics Compared to Haloperidol Clozapine: More effective than Hal., Low-potency FGA Amisulpride: More effective than Hal., Low-potency FGA Risperidone: More effective than Hal., Low-potency FGA Olanzapine: More effective than Hal., Low-potency FGA Zotepine: NOT more effective Sertindole: NOT more effective Aripiprazole: NOT more effective Quetiapine: NOT more effective Ziprasidone: NOT more effective Favor s SGA Favors FGA Leucht et al.,. Lancet. 2009(January);373:31-41
22
Findings of Meta-analysis Controlling for major biases NO DIFFERENCE IN EFFICACY BETWEEN NON-CLOZAPINE ATYPICALS –Dosing bias (non-equivalent doses) –Differences in comparator haloperidol dose –Differences in study population (more refractory for later agents) Tandon and Nasrallah, Archives of General Psychiatry 2006; 63: 935-937
