[Long-term treatment with antidepressive drugs]

Area of Science:

• Psychiatry
• Pharmacology

Context:

• Assessing long-term antidepressant treatment efficacy is challenging due to the difficulty in distinguishing between relapse and recurrence.
• A symptom-free period of 4-6 months is necessary to define recovery and initiate preventive strategies.
• Current research focuses on long-term controlled trials for newer antidepressant compounds.

Purpose:

• To review current evidence and guidelines for long-term antidepressant prescription.
• To differentiate treatment strategies for unipolar and bipolar depression.
• To highlight the role of psychotherapy and physician-patient relationship in treatment outcomes.

Summary:

• For unipolar depression, long-term (≥5 years) high-dose antidepressant therapy is favored.
• In bipolar depression, combining antidepressants with lithium may benefit patients with a depressive index episode.
• Dysthymia, panic disorder, and obsessive-compulsive disorder are recognized indications for long-term antidepressant use, though empirical evidence requires further validation through controlled trials.

Impact:

• Provides insights into evidence-based long-term antidepressant strategies for various mood and anxiety disorders.
• Emphasizes the importance of patient-physician relationship and psychotherapy for treatment adherence and success.
• Identifies areas where further research is needed to specifically assess individual antidepressant compounds for long-term use.
