Cromolyn sodium is used for prophylaxis (prevention) of asthma symptoms and is not used to treat acute asthma exacerbations. Albuterol, ipratropium, and levalbuterol HFA are bronchodilators used to relieve acute asthma symptoms by opening airways. So cromolyn sodium is contraindicated in treating acute exacerbations as it doesn't provide immediate relief.

A. Cromolyn sodium
