Ipratropium Bromide for Cough in COPD
Mechanism and Efficacy
- Ipratropium bromide therapy in stable patients with chronic bronchitis results in patients coughing fewer times with less severe cough, according to the American College of Chest Physicians (ACCP) 1, 3
Comparison with Other Bronchodilators
- The American College of Chest Physicians (ACCP) evidence-based guidelines give ipratropium bromide a grade A recommendation for improving cough in stable patients with chronic bronchitis 2, 3
Clinical Considerations and Caveats
- Ipratropium bromide has demonstrated more reliable effects on cough reduction, unlike short-acting β-agonists which show inconsistent results for cough improvement, in patients with chronic bronchitis 1, 3
- Ipratropium bromide significantly decreases the volume of sputum expectorated in patients with chronic bronchitis 1, 3
- For acute exacerbations of chronic bronchitis, ipratropium bromide is recommended alongside short-acting β-agonists, with the addition of the other agent at maximal dose if the patient doesn't show prompt response 3, 4
Treatment Algorithm
- For stable COPD patients with chronic cough, monitor for improvement in cough frequency and severity after starting ipratropium bromide 36 μg (2 inhalations) four times daily 1, 3
- Consider adding a short-acting β-agonist for additional bronchodilation and potential cough relief if response to ipratropium bromide is inadequate 3, 4
- For patients with severe airflow obstruction or frequent exacerbations, consider adding an inhaled corticosteroid with a long-acting β-agonist 1
- Use ipratropium bromide or short-acting β-agonists as first-line therapy for acute exacerbations, and add the other agent at maximal dose if response is inadequate 4
- Avoid theophylline during acute exacerbations 5
