Buspirone significantly improved major depression with anxiety compared to placebo over 8 weeks. This medication was well-tolerated and safe, showing promising results for patients with moderate depression and anxiety.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Pharmacology

Background:

  • Major depressive disorder (MDD) is a prevalent mental health condition often co-occurring with anxiety.
  • Anxiety symptoms can complicate the diagnosis and treatment of depression.
  • Identifying effective and well-tolerated pharmacological interventions for comorbid depression and anxiety is crucial.

Purpose of the Study:

  • To compare the efficacy and safety of buspirone versus placebo in treating outpatients with major depression and moderate anxiety.
  • To evaluate treatment response rates after 8 weeks of therapy.

Main Methods:

  • A double-blind, placebo-controlled study involving 155 outpatients diagnosed with major depression and moderate anxiety.
  • Participants received either buspirone or placebo for 8 weeks.

  • Treatment outcomes were assessed using physician- and patient-completed measures.
  • Main Results:

    • Buspirone treatment demonstrated significantly greater efficacy than placebo at the 8-week endpoint.
    • Seventy percent of patients receiving buspirone showed moderate to marked improvement, compared to 35% in the placebo group (p < .01).
    • Treatment discontinuation rates were 34% for buspirone and 41% for placebo. Initial anxiety and depression severity did not impact treatment outcomes. Buspirone was safe and well-tolerated up to 90 mg/day.

    Conclusions:

    • Buspirone is an effective and well-tolerated treatment option for major depression with moderate anxiety.
    • The medication shows a significant advantage over placebo in improving depressive symptoms.
    • Further research can explore optimal dosing and long-term effects in this patient population.
