OBJECTIVE Few double-blind trials have compared longer-term efficacy and safety of medications for bipolar disorder. The authors report a 47-week comparison of olanzapine and divalproex. METHOD This 47-week, randomized, double-blind study compared flexibly dosed olanzapine (5-20 mg/day) to divalproex (500-2500 mg/day) for manic or mixed episodes of(More)
OBJECTIVE The effects of olanzapine and divalproex for the treatment of mania were compared in a large randomized clinical trial. METHOD A 3-week, randomized, double-blind trial compared flexibly dosed olanzapine (5-20 mg/day) to divalproex (500-2500 mg/day in divided doses) for the treatment of patients hospitalized for acute bipolar manic or mixed(More)

The objective of this study was to compare lamotrigine (LTG) and lithium (Li) monotherapy for the treatment of BDII depression. METHODS Patients with BDII acute depression were randomized to open-label monotherapy with LTG or Li, and evaluated by trained raters blinded(More)
BACKGROUND Few controlled studies have examined the use of atypical antipsychotic drugs for prevention of relapse in patients with bipolar I disorder. Aims To evaluate whether olanzapine plus either lithium or valproate reduces the rate of relapse, compared with lithium or valproate alone. METHOD Patients achieving syndromic remission after 6(More)
