title: The expanding pharmacopoeia for bipolar disorder.
abstract: Over the past decade, the number of treatments available for bipolar disorder has undergone an extraordinary expansion. In that period, valproate and olanzapine have received regulatory approval in the United States for the acute treatment of mania, and carbamazepine has been indicated for this condition in many other countries. In addition to those agents, a number of other anticonvulsants (in particular lamotrigine, gabapentin, and topiramate) are in trials, as are the atypical antipsychotics clozapine and risperidone, and other novel compounds. This article critically reviews the evidence from controlled trials of these proposed "mood stabilizers," highlighting the strengths and limitations of the data for each compound. A major challenge to the field is the capacity to prove the prophylactic properties of agents for which effectiveness in acute mania and/or bipolar depression has been demonstrated. Finally, as the mechanisms of agents such as lithium are now becoming apparent, and the possibility of understanding the molecular defects underpinning the condition is no longer highly fanciful, the prospect of targeted therapies is considered feasible by both academia and the pharmaceutical industry.
