Abstract
OBJECTIVE: This study evaluated the effectiveness, safety, and quality of life (Qol) offered by olanzapine in first-episode schizophrenia. METHOD: One hundred and eighty-two patients with first-episode schizophrenia (ICD-10) drawn from a larger, naturalistic, study were evaluated after 6 months of treatment with olanzapine, risperidone, or conventional antipsychotics (CA). Clinical status was assessed using the Clinical Global Impression-Severity (CGI-S) and Global Assessment of Function (GAF). AWAD and EuroQol scales were used to evaluate patients' attitude towards medication and Qol, respectively. RESULTS: Subjects treated with olanzapine, risperidone, and CA showed similar improvements on CGI-S and GAF. Treatment-emergent, extrapyramidal symptoms were significantly lower in olanzapine-treated patients (17.8%) than in the risperidone (46.4%) and CA (62.2%) groups. Compared to CA, olanzapine and risperidone showed significantly greater improvement on the visual analog scale of EuroQol. Olanzapine-treated patients also showed significantly improved AWAD scores. CONCLUSIONS: In first-episode schizophrenia, atypical antipsychotics were effective, and improved Qol. Olanzapine had a lower incidence of extrapyramidal symptoms and better subjective acceptance of medication.
