Acute bronchitis, a common cough illness, is primarily caused by viruses. Antibiotics are not recommended, but albuterol may shorten cough duration, with education reducing unnecessary antibiotic use.

Area of Science:

  • Internal Medicine
  • Pulmonology
  • Infectious Diseases

Background:

  • Acute bronchitis is a prevalent cough illness in healthy adults, typically resolving within 1-3 weeks.
  • Viral respiratory infections are the primary cause of uncomplicated acute bronchitis.
  • Pertussis infection can be a factor in persistent coughs exceeding 2-3 weeks.

Purpose of the Study:

  • To review the pathophysiology of acute bronchitis.
  • To outline a practical approach for evaluating and treating adults with uncomplicated acute bronchitis.
  • To provide evidence-based recommendations for management.

Main Methods:

  • Literature review of pathophysiology, evaluation, and treatment strategies.
  • Analysis of randomized, placebo-controlled trials on antibiotic and albuterol efficacy.

Related Experiment Videos

  • Examination of intervention studies on reducing antibiotic prescribing.
  • Main Results:

    • Transient bronchial hyperresponsiveness is a key mechanism for cough.
    • Pneumonia is unlikely in patients without abnormal vital signs.
    • Antibiotic treatment is not supported by evidence for uncomplicated acute bronchitis.
    • Inhaled albuterol has demonstrated efficacy in reducing cough duration.
    • Patient and physician education can decrease antibiotic treatment rates without compromising care quality.

    Conclusions:

    • Acute bronchitis is predominantly viral, and antibiotics are generally not indicated.
    • Bronchodilators like albuterol may offer symptomatic relief.
    • Effective management strategies focus on ruling out pneumonia and judicious antibiotic use through education.
