Combined psychotherapy plus benzodiazepines for panic disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Pharmacology

Background:

• The combination of psychotherapy and benzodiazepines is frequently used for panic disorder, but its efficacy remains uncertain.
• Existing research has not definitively established the benefits of this combined approach over monotherapy.

Purpose of the Study:

• To systematically review and analyze randomized controlled trials comparing the efficacy of combined psychotherapy and benzodiazepine treatment versus monotherapy for panic disorder.

Main Methods:

• Searched major databases (e.g., Cochrane DANE) and contacted experts for relevant randomized trials.
• Included studies compared combined therapy with psychotherapy alone or benzodiazepine alone in adults with panic disorder.
• Data were extracted, quality assessed, and random-effects meta-analyses were performed on the primary outcome of 'response'.

Main Results:

• Three trials met eligibility criteria, utilizing behavior therapy or cognitive-behavior therapy.
• No significant differences were found when comparing combination therapy with psychotherapy alone, though a trend towards inferiority at follow-up was observed.
• Limited evidence suggested a potential borderline significant benefit of combination therapy over benzodiazepine monotherapy at the end of treatment, but this was not sustained at follow-up.

Conclusions:

• There is a significant lack of high-quality evidence regarding the efficacy of combining psychotherapy with benzodiazepines for panic disorder.
• Current evidence is insufficient to confidently assess the clinical effects and guide treatment decisions for patients with panic disorder receiving this combination therapy.
