This is a randomized, open-label, pilot clinical trial of spironolactone suspension versus
oral prednisolone for use in Duchenne muscular dystrophy. The goals are to determine the
safety of 6 months of treatment with spironolactone treatment int he steroid-naive DMD
population as well as to determine if either spironolactone or a standard clinical dose of
corticosteroids results in equivalent improvement in time to complete the 100 meter timed
test (100M).
