Divalproex sodium is an anticonvulsant agent approved for use either alone or in combination with other antiepileptic drugs for simple and complex absences seizures and mania. Four double-blind placebo-controlled studies have confirmed that divalproex sodium/valproate is an effective migraine treatment. In all of the clinical studies, whether open, retrospective, or placebo-controlled and double-blind, valproate was an effective preventive treatment for migraine. There was a reduction in the number of migraine attacks, and migraine duration and intensity were also reduced in some instances. It is equally as effective in patients with severe frequent migraines as in those with less severe migraines. In clinical trials, the most frequent adverse events reported by patients treated with divalproex sodium were nausea, asthenia, dyspepsia, dizziness, somnolence, and diarrhea, with most adverse events being mild to moderate in severity.

To compare the efficacy of sodium valproate administered as adjunct to neuroleptic medication for patients with acute mania with the efficacy of neuroleptics alone, the authors conducted a 21-day, randomized, double-blind, parallel-group, placebo-controlled trial. The study design closely reflected a clinical psychiatric setting in Europe where patients with acute mania commonly receive neuroleptic medication. In this trial, 136 hospitalized patients met the ICD-10 criteria for acute manic episodes; these patients received a fixed dose of 20 mg/kg of body weight of sodium valproate (Orfiril, Desitin Arzneimittel GmbH, Hamburg, Germany) orally, in addition to basic neuroleptic medication, preferably haloperidol and/or perazine. The primary outcome measure was the mean dose of neuroleptic medication (after conversion into haloperidol-equivalents) for the 21-day study period. Severity of symptoms was measured using the Young Mania Rating Scale (YMRS), the Global Assessment Scale, and the Clinical Global Impression Scale. Intent-to-treat analysis was based on 69 patients treated with valproate and 67 patients who received placebo. Groups were comparable with regard to demographic and clinical baseline data. Premature discontinuations occurred in only 13% of the patients. The mean neuroleptic dose declined continuously in the valproate group, whereas only slight variations were observed in the placebo group; the difference was statistically significant (p = 0.0007) for study weeks 2 and 3. The combination of neuroleptic and valproate proved superior to neuroleptics in attempts to alleviate manic symptoms. The proportion of responders (a 50% improvement rate shown on the YMRS) was higher for the combination with valproate than for the group receiving only neuroleptics (70% vs. 46%; p = 0.005). Adverse events consisted of those known for valproate or neuroleptics; the only adverse event was asthenia, which occurred more frequently with the combination therapy. Valproate represents a useful adjunct medication for the treatment of acute manic symptoms. Valproate is beneficial because it allows the administration of fewer neuroleptic medications and produces improved and quicker remission of manic symptoms.

Quetiapine (QTP) combined with lithium (Li) or divalproex (DVP) for the treatment of mania was evaluated in 2 double-blind, placebo-controlled studies. Patients were randomized to 3 or 6 weeks of treatment with QTP plus Li/DVP or placebo (PBO) plus Li/DVP. Quetiapine was dosed up to 800 mg/d; Li was dosed to achieve serum concentrations of 0.7-1.0 mEq/L and DVP to 50-100 microg/mL. A total of 402 patients were randomized: 197 to QTP + Li/DVP and 205 to PBO + Li/DVP. The mean quetiapine dose in responders was 492 (+/-204) mg/d. Improvement in the Young Mania Rating Scale (YMRS) at day 21 in the QTP + Li/DVP group (-15.29) was statistically superior to the PBO + Li/DVP group (-12.19) (P < 0.05). A statistically significant difference in favor of quetiapine was observed within the first week (P < 0.05). Significantly more QTP + Li/DVP patients achieved a response (> or =50% decrease in the YMRS) at day 21 (QTP + Li/DVP, 55.7%; PBO + Li/DVP, 41.6%;P < 0.01). Improvements in Clinical Global Impression-Bipolar Severity of Illness scores by day 21 were also significantly greater in QTP + Li/DVP-treated patients (-1.59) versus PBO + Li/DVP (-1.19) (P < 0.01). Common adverse events (> or =5% and twice that in the PBO + Li/DVP group) in the QTP + Li/DVP group were somnolence, dry mouth, and asthenia. Quetiapine combined with Li/DVP was not associated with extrapyramidal symptoms (including akathisia) or emergent depression. More QTP + Li/DVP-treated patients completed the trial, and there was no difference in discontinuation rates due to adverse events between the two groups. Quetiapine, in combination with lithium or divalproex, is well tolerated and has superior efficacy to lithium or divalproex alone in the treatment of bipolar mania.

This study evaluated the efficacy and safety of two fixed doses of aripiprazole (15 mg/day, n = 131 and 30 mg/day, n = 136) compared with placebo (n = 134) in acutely manic or mixed bipolar I hospitalized patients. The mean change from baseline to Week 3 in the YMRS Total Scores was -10.01 (95% CI: -11.92, -8.09) for aripiprazole 15 mg/day, -10.80 (95% CI: -12.71, -8.90) for aripiprazole 30 mg/day, and -10.12 (95% CI: -12.01, -8.24) for placebo. The most frequent adverse events (> or = 10% and greater than placebo) for either of the aripiprazole treatment groups were headache, nausea, dyspepsia, insomnia, agitation, constipation, akathisia, anxiety, lightheadedness, vomiting, diarrhea, asthenia and extremity pain. Aripiprazole 15 or 30 mg/day was not significantly more effective than placebo in the treatment of bipolar I disorder acute mania at endpoint (Week 3). A high placebo response rate may have accounted for the lack of separation between treatment groups.
