Trimipramine in physical illness with depression

Area of Science:

• Psychiatry and Internal Medicine

Background:

• Major depression frequently co-occurs with serious physical disorders.
• Treatment of depression in medically ill patients presents unique challenges.
• Tricyclic antidepressants are a potential therapeutic option for comorbid depression.

Purpose of the Study:

• To evaluate the efficacy of trimipramine, a tricyclic antidepressant, in medically ill patients with major depression.
• To determine if trimipramine improves depressive symptoms irrespective of the course of the underlying physical condition.

Main Methods:

• A 6-week, double-blind, randomized trial was conducted.
• 42 outpatients with serious physical disorders and major depression (RDC criteria, Raskin score ≥7) were enrolled.
• Participants received either trimipramine or a placebo.

Main Results:

• In the placebo group, depressive symptom improvement correlated with physical disorder improvement.
• Trimipramine treatment led to significant improvement in depressive symptoms.
• Improvement in depressive symptoms with trimipramine occurred even without concurrent improvement in the physical disorder.

Conclusions:

• Trimipramine is an effective treatment for major depression in medically ill patients.
• Tricyclic antidepressants can alleviate depressive symptoms independently of the physical health status.
• This suggests a specific antidepressant effect rather than a secondary improvement due to physical healing.
