Meta Analysis Comparative Study
An integrated analysis of acute treatment-emergent extrapyramidal syndrome in patients with schizophrenia during olanzapine clinical trials: comparisons with placebo, haloperidol, risperidone, or clozapine.
The frequency and severity of extrapyramidal syndrome (EPS) were evaluated in patients with DSM-III or DSM-IV schizophrenia in the acute phase (- 8 weeks) of randomized, double-blind, controlled trials from the integrated olanzapine clinical trial database. ⋯ This analysis of available data from olanzapine clinical trials lends additional support to olanzapine's favorable EPS profile.
