Metoprolol Efficacy in Treating Anxiety: Clinical Evidence
Metoprolol for General Anxiety Symptoms
Research shows that metoprolol, a beta-blocker, can significantly reduce anxiety symptoms in patients diagnosed with anxiety neurosis. In a study of patients with moderate to severe anxiety, metoprolol led to a statistically significant improvement in anxiety scores, especially in reducing physical (somatic) symptoms of anxiety. Side effects were minimal, suggesting metoprolol could be a useful alternative to other beta-blockers like propranolol for anxiety management .
Metoprolol in Pre-Operative Anxiety
Several studies have evaluated metoprolol’s effect on anxiety before surgery. In double-blind trials, patients who received metoprolol before surgery reported greater relief from anxiety compared to those who received a placebo. Both patient self-assessments and anesthetist evaluations confirmed that metoprolol reduced anxiety and improved calmness before anesthesia. Additionally, metoprolol lowered blood pressure and heart rate, which are often elevated due to anxiety Jakobsen1989Jakobsen1990.
Metoprolol and Anxiety in Chronic Heart Failure Patients
For patients with chronic heart failure (CHF) who also experience anxiety, metoprolol treatment has shown benefits. Over a 12-month period, CHF patients treated with metoprolol experienced significant improvements in quality of life, including those with anxiety. Importantly, while depressive and burnout symptoms sometimes worsened, anxiety symptoms specifically improved with metoprolol, and this effect was independent of the drug’s impact on heart rate Zhang2019Liu2017.
Safety and Considerations
Across studies, metoprolol was generally well tolerated with minimal side effects when used for anxiety. However, in CHF patients, while anxiety improved, depressive and burnout symptoms could worsen, so careful monitoring is recommended for patients with multiple mental health concerns Chaturvedi1985Liu2017.
Conclusion
Metoprolol has demonstrated efficacy in reducing anxiety symptoms in various settings, including general anxiety disorders, pre-operative anxiety, and in patients with chronic heart failure. Its anxiolytic effects are well supported, especially for somatic symptoms, and it is generally safe, though caution is needed in patients with coexisting depression or burnout.

Effects of β-blockers and anxiety on complication rates after acute myocardial infarction.
Anxious patients after acute myocardial infarction had more complications and longer stays, and metoprolol administration did not eliminate this relationship, possibly due to insufficient doses.
