Anxiety Disorder Treatment

Introduction to Anxiety Disorder Treatment

• Anxiety disorders can be treated with various interventions, including pharmacological and non-pharmacological approaches, as recommended by the National Institute of Mental Health and American Psychiatric Association 1, 2, 3

Pharmacological Interventions

• Propranolol can be used as an adjunctive treatment for symptom relief in panic disorder, combined with cognitive behavior therapy and/or SSRIs, as recommended by guidelines from reputable organizations such as the American Psychiatric Association 4
• Propranolol is contraindicated in patients with asthma or COPD, heart block greater than first degree, cardiogenic shock, or heart failure, due to potential adverse cardiovascular effects, as advised by the American College of Cardiology and American Heart Association 5, 2, 1
• The recommended dose of propranolol for anxiety with physical symptoms is 20-40 mg, 1-3 times a day, with women potentially requiring lower doses due to higher oral bioavailability and slower clearance via CYP2D6 2, 6
• Common side effects of propranolol include bradycardia, hypotension, sleep disturbances, respiratory effects, and changes in skin color, with a strength of evidence rated as high 7, 2, 1
• Propranolol may potentially induce depression in predisposed patients, although the evidence is not strongly supported and requires further study 2

Non-Pharmacological Interventions

• The National Institute of Mental Health and American Psychiatric Association recommend that SSRIs/SNRIs and Cognitive Behavioral Therapy be used as first-line treatments for chronic anxiety disorders 1, 2, 3
• Cognitive Behavioral Therapy is a recommended first-line treatment for anxiety disorders, with a strength of evidence rated as high 1, 2, 3

Treatment Guidelines

• The Canadian Clinical Practice Guidelines and other recent guidelines specifically deprecate propranolol for social anxiety disorder based on negative evidence, with a strength of evidence that is not strongly supported 2
• Propranolol is not recommended as a first-line treatment for generalized anxiety disorder due to insufficient evidence of effectiveness, as stated by the Canadian Clinical Practice Guidelines and recent guidelines 2

Special Populations

• Recent evidence suggests that propranolol may have some benefit for anxiety symptoms in autism spectrum disorder, but more research is needed to confirm this, with a strength of evidence rated as low 1
• Propranolol may be beneficial for performance anxiety with somatic symptoms, particularly for physical symptoms like tremor and palpitations, in populations such as anxious musicians, with limited evidence supporting its effectiveness 2
• Some evidence suggests atenolol may be better tolerated than propranolol for anxiety symptoms, although the evidence is limited and not strongly supported, with no clear comparison or control group 2

Contraindications and Precautions

• The American Academy of Pediatrics and American Heart Association suggest that propranolol should not be used in patients with certain heart conditions, such as sinus bradycardia, heart block greater than first degree, cardiogenic shock, or heart failure 1
• The American Thoracic Society recommends that propranolol should not be used in patients with asthma or COPD due to the risk of severe bronchospasm 1
• The World Health Organization recommends that propranolol be used with caution in patients with depression, as it may worsen depressive symptoms in predisposed individuals, with a strength of evidence rated as moderate 1
