Duchenne Muscular Dystrophy (DMD)

Tadalafil, Sildenafil Increase Blood Flow to DMD-Affected Muscles

A study conducted in 10 boys with Duchenne muscular dystrophy (DMD) has found that blood flow to exercising muscles is deficient and that treatment with either tadalafil (Cialis) or sildenafil (Viagra) normalizes this blood flow, at least in the short term (after one dose of either drug).

Tadalafil and sildenafil, both PDE5 inhibitors, are approved by the U.S. Food and Drug Administration (FDA) to treat erectile dysfunction.
