Treatment of Bipolar Disorder with Lamotrigine and Aripiprazole

Efficacy and Safety

• The American Academy of Child and Adolescent Psychiatry recommends lamotrigine for maintenance therapy in adults with bipolar disorder, and aripiprazole for acute mania in adults 1
• Aripiprazole is less likely to cause extrapyramidal symptoms compared to typical antipsychotics, though risk increases with long-term treatment, according to the Annals of Oncology 2
• Risperidone carries increased risk of extrapyramidal symptoms when doses exceed 6 mg/24 hours, and may cause insomnia, agitation, anxiety, drowsiness, and orthostatic hypotension, as reported in the Annals of Oncology 2

Guideline Support and Clinical Considerations

• The American Academy of Child and Adolescent Psychiatry suggests that medication choice should prioritize: (1) evidence of efficacy, (2) phase of illness, (3) side effect spectrum and safety, (4) patient's history of medication response 1
• For agitated but cooperative patients, oral benzodiazepine + oral risperidone combinations are recommended specifically for acute agitation management, not maintenance treatment, according to the Annals of Emergency Medicine 3, 4, 5
• Lamotrigine provides specific benefit for bipolar depression prevention, whereas risperidone lacks efficacy data for this indication, as stated in the Journal of the American Academy of Child and Adolescent Psychiatry 1
