Corticosteroids ease symptoms of asthmaAccording to a review of studies comparing inhaled corticosteroids and cromolyn, it was noted that adults and children suffering from asthma and using inhaled corticosteroids fared better than those using cromolyn.

James Guevara, M.D., of the University of Pennsylvania School of Medicine and colleagues, said that patients on steroids had on average three fewer severe asthma flare-ups each year, scored better on lung function tests, and make lesser use of inhalers than their counterparts on cromolyn.

William Storms, M.D., an allergist at the University of Colorado Health Sciences Center and director of the William Storms Allergy Clinic in Colorado Springs, said that the consensus still provides room for cromolyn treatment.
