Olanzapine (Zyprexa, Eli Lilly & Co.) is an atypical antipsychotic medication with once-daily dosing that was originally developed for the treatment of schizophrenia. It has shown broad efficacy in the treatment of bipolar mixed and manic episodes, but is less effective in the treatment of bipolar depression. Double-blind studies have demonstrated a rapid onset of action in acute bipolar mania, significantly greater rates of response compared with placebo, and a remission rate of 88.3% in a 49-week open-label study. Diverse presentations of the illness responded well to olanzapine including patients with rapid-cycling bipolar disorder, mixed episodes, as well as psychotic and nonpsychotic manias. Olanzapine monotherapy improved symptoms of depression related to its sedating and appetite-enhancing profile, but core symptoms such as depressed mood did not improve significantly. However, in combination with fluoxetine, bipolar depressed patients responded without an increased risk of mania. Weight gain and sedation are prominent adverse effects, and it has been associated with atherogenic dyslipidemia and glucose intolerance.

Management of bipolar disorder (BPD) may require multiple medications, including lithium, anticonvulsants, and antipsychotics (both conventional and atypical). Updated treatment guidelines reflect an expanded role for atypical antipsychotics (AAPs) in BPD treatment. Five AAPs--olanzapine, risperidone, quetiapine, ziprasidone, and aripiprazole--are approved by the US Food and Drug Administration (FDA) as monotherapy for first-line treatment of acute manic and (except for quetiapine) mixed episodes. Two AAPs--olanzapine (in fixed-dose combination with fluoxetine) and quetiapine--are also FDA approved for bipolar depression. For long-term maintenance therapy, one option is to continue effective, well-tolerated acute phase treatment; however, only olanzapine and aripiprazole are FDA approved for maintenance, based on evidence from randomized, placebo-controlled clinical trials. Although head-to-head comparisons are scarce, meta-analysis data suggest that olanzapine, risperidone, quetiapine, ziprasidone, and aripiprazole have similar antimanic efficacy; therefore, AAP selection for this indication should be guided by other considerations such as safety, tolerability, and cost. Safety and tolerability issues to consider when selecting an AAP include metabolic dysfunction (weight gain, type 2 diabetes, and dyslipidemia); hyperprolactinemia; extrapyramidal symptoms; QTc prolongation; and pharmacokinetic drug interactions.
