Clinical observations of nebulized flunisolide in infants and young children with asthma and bronchopulmonary dysplasia.

Severe bronchopulmonary dysplasia (BPD) is frequently associated with asthma. The combination is often severe enough to necessitate corticosteroid therapy. There are no commercially available nebulizer solutions of corticosteroids for use in infants and young children. Seven infants and small children with very severe BPD and asthma aged 6-24 months, were treated with flunisolide, 187-250 micrograms q.i.d. in the form of nasal spray delivered by nebulizer. After treatment for 2.5-20 months, four patients showed clinical improvement, one initially improved but later deteriorated and died of cardiac failure, and two patients showed no improvement and died within 3 months. The number of days of hospitalization was significantly reduced from 8.4/month to 2.5/month (P less than 0.05). No side-effects were detected and it was felt that the three patients who died, did so as a consequence of very severe BPD and its cardiac consequences. The suspension remained stable for 80 min when mixed with normal saline, cromolyn sodium, albuterol, or acetylcysteine. It is concluded that nebulized flunisolide is a potentially useful treatment for infants and young children with asthma and BPD.
