Sodium Nitrate to Improve Blood Flow

key information

study id #: NCT02847975

condition: Becker Muscular Dystrophy

status: completed


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

results: https://clinicaltrials.gov/ct2/show/results/NCT02847975

last updated: November 21, 2018

study details

start date: October 2013

estimated completion: December 2014

phase of development: Phase 1

size / enrollment: 11

primary outcomes:

  • 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.
