Is nedocromil effective in preventing asthmatic attacks in patients with asthma?

In general, about 50% to 70% of patients respond to nedocromil (SOR: A, multiple RCTs and meta-analyses). Unfortunately, which patients respond is not predictable from clinical parameters. Nedocromil is worth trying in mild persistent asthma, particularly for children where the parents are worried about the growth issues associated with inhaled steroids. Side effects (sore throat, nausea, and headache) are mild and infrequent. Maximal efficacy is usually seen after 6 to 8 weeks
