Summary

This project will assess the vascular responsiveness in leg muscles of boys with Duchenne muscular dystrophy (DMD) to one single dose of tadalafil, a common vasodilator drug, using non-invasive techniques (MRI or Doppler ultrasound) and exercise testing. These findings will provide proof of concept for a subsequent intervention study to demonstrate efficacy of longer-term tadalafil to counter sympathetic vasoconstriction and slow disease progression in DMD. It will also inform whether a group of patients do not respond to the drug.
