Combivent is a combination product containing ipratropium bromide and which other agent?

• A. Cromolyn sodium
• B. Albuterol
• C. Acetylcysteine
• D. Dornase alpha

Answer: (B)

Combivent pairs ipratropium bromide with a fast-acting bronchodilator to maximize relief of bronchospasm. Ipratropium blocks muscarinic receptors in the airways, reducing acetylcholine-driven constriction, while albuterol stimulates beta-2 receptors to relax the smooth muscle. Using these two mechanisms together gives additive bronchodilation, helping open the airways more effectively than either agent alone. Other options aren’t bronchodilators used in this combination: cromolyn sodium is a mast cell stabilizer used for prophylaxis, acetylcysteine is a mucolytic, and dornase alfa is a DNase used in cystic fibrosis.
