According to a new review of recently concluded studies comparing inhaled corticosteroids and the medicine cromolyn, asthmatic patients, including children and adults, can exercise a better control over their asthma and breathe deeper with inhaled corticosteroids.

James Guevara, M.D., of the University of Pennsylvania School of Medicine and colleagues said that asthmatic patients treated with steroids have an advantage of scoring higher in lung function tests. It was also remarked by them that the usage of corticosteroids allow patients to make lesser use of inhalers than patients who makes use of cromolyn.

“To our knowledge, this is the first systematic review comparing the effects of cromolyn to the gold standard, inhaled steroids,” Guevara said.

The review appears in the current issue of The Cochrane Library, a publication of The Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.

The consensus still leaves room for cromolyn treatment, according to 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.

“Any expert would agree that inhaled corticosteroids are preferred first-line therapy for treatment of persistent asthma, which requires daily therapy. But we also will agree with the NIH [National Institutes of Health] asthma guidelines, which state that cromolyn and other drugs are alternative therapies,” Storms said.

Cromolyn, or sodium cromoglycate, and inhaled corticosteroids both block the action of certain inflammatory cells in the lungs. Physicians recommend both types of medication for persistent asthma, but individual studies disagree about which type of medication works best, the reviewers found.

Guevara and colleagues said that inhaled corticosteroids are superior to cromolyn irrespective of asthma severity level and also said that the attained results are so decisive that there is no need for any future study on this matter.
