How effective is intal (cromolyn sodium) whenused in a nebulizer?

Fair. Cromolyn is effective for a subclass of patients with asthma. We lack a blood or other test to identify those persons who are likely to respond so you have to try everyone. The trial requires administration 4x/day for 30 days. Its hard for many people to stay on this schedule so some people who might be helped do not benefit. Once shown to work some folks can take cromolyn 3x or twice a day.
