Cromolyn sodium for the prevention of chronic lung disease in preterm infants.

Chronic lung disease (CLD) frequently occurs in preterm infants (< 37 weeks gestational age) and has a multifactorial etiology including inflammation. Cromolyn sodium is a mast cell stabiliser that inhibits neutrophil activation and neutrophil chemotaxis. Therefore it is possible that cromolyn sodium might have a role in the prevention of CLD.
