Combination Therapy with Ipratropium Bromide and Beta-Agonists

Rationale for Combination Therapy

• The National Asthma Education and Prevention Program (NAEPP) recommends adding ipratropium 0.5 mg to beta-agonists every 20 minutes for 3 doses in moderate-to-severe exacerbations 1
• In adults with severe asthma exacerbations, add ipratropium bromide 500 µg to the beta-agonist if initial response is inadequate 3

Evidence-Based Recommendations

• The American Thoracic Society gives ipratropium bromide a Grade A recommendation for improving cough in stable chronic bronchitis, reducing cough frequency, severity, and sputum volume 2, 4
• Standard dosing is ipratropium 36 μg (2 inhalations) four times daily for maintenance therapy 2

Clinical Algorithm

• Continue Xopenex at current dose and add ipratropium bromide 1
• For nebulized therapy: Mix 0.5 mg ipratropium with 2.5 mg albuterol-equivalent (or levalbuterol at half the dose) in the same nebulizer 1
• For MDI: Administer 4-8 puffs of ipratropium every 20 minutes as needed for acute symptoms 1

Important Caveats

• Use mouthpiece rather than mask in elderly patients to minimize risk of glaucoma from ipratropium exposure to eyes 3
• Never discontinue the beta-agonist (Xopenex) to use ipratropium alone, as beta-agonists remain first-line for acute symptom relief 5
