Absorption of digoxin in children with cystic fibrosis.

The absorption of digoxin in cystic fibrosis was evaluated in 16 subjects 
by assessing the relationship between dosage expressed in mug/kg/day and serum 
digoxin concentration. The results indicate that the same relationship exists between 
maintenance dosage and serum levels in these patients and in patients 
without cystic fibrosis. Thus, no evidence of impaired absorption was found.
