The impact of response to previous mood stabilizer therapy on response to olanzapine versus placebo for acute mania

Abstract

Olanzapine has been shown to be superior to placebo for the treatment of mania. This secondary analysis suggests that olanzapine monotherapy is similarly effective for patients whether or not they previously have failed to respond to another mood stabilizer for mania. A study limitation is that response to lithium or valproate was determined retrospectively.
