Sodium Nitrate to Improve Blood Flow
study id #: NCT02847975
condition: Becker Muscular Dystrophy
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.
intervention: Sodium nitrate
mechanism of action: Nitrate supplement to alter funcitonal muslce ischaemia
last updated: November 21, 2018
start date: October 2013
estimated completion: December 2014
phase of development: Phase 1
size / enrollment: 11
- change in muscle tissue oxygenation [ Time Frame: change from baseline to post treatment (3-4 hours) ]
The pre-specified primary outcome is the pre vs. post treatment change in functional sympatholysis measured by muscle oxygenation.
