HealthDay News — The US Food and Drug Administration has approved Emflaza (deflazacort) to treat Duchenne muscular dystrophy (DMD) in patients 5 years and older.

The corticosteroid is designed to reduce inflammation and suppress the immune system in patients with DMD, the most common type of muscular dystrophy. 

The FDA said it’s the first corticosteroid approved to treat DMD. Emflaza was evaluated in a clinical study of 196 males aged 5 to 15, all with documented mutation of the dystrophin gene and onset of DMD symptoms before age 5. 

After 12 weeks, patients taking the drug showed muscle strength improvement, compared with those who took a placebo.

Emflaza is marketed by Marathon Pharmaceuticals, based in Northbrook, Illinois.
