The excretion of free cortisol in two 24 hour urine samples, collected at the end of each treatment period, was significantly higher (mean = 76.3 nmol per day) during budesonide treatment than during beclomethasone treatment (mean = 53.7 nmol per day) (p less than 0.01). The difference between the two drugs was more pronounced in the eight children who received 1,000 and 1,200 micrograms per day than in the 22 children who received 800 micrograms per day. Four children had cortisol excretion below the normal range when treated with beclomethasone. This was seen in one child during budesonide treatment. The age of the child did not influence the result. The long term clinical significance of these findings has yet to be elucidated.
