5. Study Description
Brief Summary
Investigators recently showed that tadalafil restores functional sympatholysis in patients with Becker muscular dystrophy (BMD). If tadalafil restores functional sympatholysis in BMD via the NO-cyclic guanosine monophosphate pathway, then functional sympatholysis should also be restored by sodium nitrite- which is an indirect nitric oxide donor.
