Bipolar disorder is a highly recurrent illness requiring maintenance treatment with mood-stabilizing medications to decrease the risk of recurrent mood episodes. Preferred medications for bipolar maintenance treatment include lithium, the anticonvulsants valproate and lamotrigine, and the second-generation antipsychotic quetiapine. (Choices A and E) Bupropion, a norepinephrine dopamine reuptake inhibitor, and paroxetine, a selective serotonin reuptake inhibitor, are antidepressants that have the potential to precipitate manic episodes. Antidepressant monotherapy should be avoided in bipolar maintenance treatment due to the risk of mood destabilization. (Choices B and C) Chlorpromazine and haloperidol are first-generation antipsychotics (FGAs) used in the treatment of schizophrenia. FGAs may be used in combination with lithium or valproate for treatment of severe mania, but are not used as monotherapy for maintenance treatment of bipolar disorder. (Choice D) Lorazepam is a benzodiazepine that can be used as an adjunct to mood stabilizers in the treatment of acute mania; it is not recommended for maintenance treatment. Educational objective: The anticonvulsant valproate has mood-stabilizing properties and is an effective maintenance treatment for bipolar disorder. Other maintenance options for bipolar disorder include lithium, lamotrigine, and quetiapine. __________ References: Effectiveness of psychotropic medications in the maintenance phase of bipolar disorder: a meta-analysis of randomized controlled trials.
