From the Guidelines

No, there is no evidence supporting the use of hydralazine for anxiety or panic attacks. Hydralazine is a vasodilator medication primarily used to treat high blood pressure and heart failure by relaxing blood vessels. It is not approved or recommended for treating anxiety disorders. In fact, hydralazine can occasionally cause side effects like palpitations, tachycardia, and headaches, which might actually worsen anxiety symptoms in some individuals.

Established Treatments for Anxiety and Panic Attacks

For anxiety and panic attacks, established treatments include:

  • Selective serotonin reuptake inhibitors (SSRIs) like sertraline (50-200 mg daily) or escitalopram (10-20 mg daily) 1
  • Benzodiazepines like lorazepam (0.5-2 mg as needed) for acute symptoms
  • Cognitive behavioral therapy
  • Relaxation techniques These treatments target the neurochemical imbalances and thought patterns associated with anxiety, whereas hydralazine's mechanism of action has no known beneficial effect on anxiety pathways in the brain.

Importance of Evidence-Based Treatments

If you're experiencing anxiety or panic attacks, it's essential to consult with a healthcare provider who can recommend appropriate evidence-based treatments, as noted in the clinical practice guideline for the assessment and treatment of children and adolescents with anxiety disorders 1. The guideline emphasizes the importance of comprehensive, evidence-based assessment to enhance evidence-based treatment.

Other Considerations

While beta-blockers are sometimes used to treat performance anxiety and panic disorder, as mentioned in a study on individualized beta-blocker treatment for high blood pressure 1, hydralazine is not indicated for these conditions. The most recent and highest quality study on the topic, a clinical practice guideline published in 2020, does not support the use of hydralazine for anxiety or panic attacks 1.

From the Research

Evidence for Hydralazine in Anxiety or Panic Attacks

  • There is no direct evidence to support the use of hydralazine for anxiety or panic attacks in the provided studies 2, 3, 4, 5, 6.
  • The studies primarily focus on the treatment of generalized anxiety disorder, panic disorder, and social anxiety disorder using various medications such as hydroxyzine, selective serotonin reuptake inhibitors (SSRIs), benzodiazepines, and others.
  • Hydralazine is not mentioned in any of the provided studies as a treatment option for anxiety or panic attacks.

Alternative Treatment Options

  • Hydroxyzine, an anti-histamine medication, has been shown to be effective in alleviating the acute symptoms of generalized anxiety disorder (GAD) compared to placebo 2.
  • SSRIs, such as fluvoxamine, fluoxetine, paroxetine, sertraline, and citalopram, have been proven to be superior to pill-placebo in the treatment of panic disorder and agoraphobia 3.
  • Benzodiazepines (BZs) and SSRIs are effective in the pharmacologic treatment of panic disorder, but SSRIs are generally favored over BZs due to their side effect profile 4.

Limitations and Future Directions

  • The provided studies have limitations, such as high risk of bias, small sample sizes, and limited generalizability, which affect the reliability of the findings 2, 4, 5.
  • Further research is needed to investigate the efficacy and safety of various medications, including hydralazine, in the treatment of anxiety and panic disorders 6.
