N2 - INTRODUCTION: Previous studies comparing olanzapine (OLZ) and risperidone (RIS) have tended to focus on multiple-episode patients, with no studies examining their comparative efficacy in a non-selective sample of first-episode psychosis. METHODS: The Early Psychosis Prevention and Intervention Centre in Australia had admitted 786 first-episode psychosis (FEP) patients between 1998-2000. Data were collected from the medical records (MR) of 367 patients, which met inclusion criteria. The primary objective was to evaluate the efficacy of OLZ vs. RIS as measured by CGI-S, CGI-BP (symptomatic level), GAF and SOFAS (functioning level). RESULTS: 367 FEP patients were entered into the study, 278 in the RIS- (2.7 mg/day) and 89 in the OLZ group (10.2 mg/day). No between-group differences were found in non-affective FEP (n = 273). In affective FEP patients (n = 94), mainly treated for acute mania (86.7 %), OLZ treatment was related to better response on the symptomatic (CGI-S; p = .002), but not on the functioning level (GAF and SOFAS; ns). There were trends in the OLZ group towards a higher rate of remission of positive symptoms ( p = .054) and a shorter treatment duration to reach this remission in affective FEP patients ( p = .077).
