It is common for lithium to be combined with other mood-stabilizing drugs or antipsychotic drugs, if necessary, in order to achieve more complete remission of symptoms. Studies indicate that monotherapy is often insufficient to reach this goal.17... 

Divalproex sodium is comprised of sodium valproate and valproic acid. The delayed-release and extended-release formulations are converted in the small intestine into valproic add, which is the systemically absorbed form. It was developed as an antiepileptic drug, but also has efficacy for mood stabilization and migraine headaches. It is FDA-approved for the treatment of the manic phase of bipolar disorder. It is generally equal in efficacy to lithium and some other drugs for bipolar mania. It has particular utility in bipolar disorder patients with rapid cycling, mixed mood features, and substance abuse comorbidity. Although not FDA-approved for relapse prevention, studies support this use, and it is widely prescribed for maintenance therapy. Divalproex can be used as monotherapy or in combination with lithium or an antipsychotic drug.31...

The dosages of antipsychotic drugs differed markedly between the six sites studied (see Table 12.2). Of note, there were more than 50% of patients in China, Hong Kong, Taiwan, and Singapore taking less than 600 mg chlorpromazine-equivalents... 

Thirty-five to eighty-seven percent of the patients studied received antiparkinson drugs. Compared to other countries, Japan and Singapore used the most of these antidotes for drug-induced extrapyramidal symptoms. This is most likely related to the frequent use of high-dosage antipsychotic drugs and poly-antipsychotics (see Table 12.3).
