Study Summary

This proposal hypothesizes that oral supplementation with sodium nitrite or nitrate will result in in vivo conversion of nitrate to nitrite and nitrite to nitric oxide with limited toxicity in the doses proposed in healthy adult normal volunteers. We utilize a powerful in vivo technique (pharmacokinetic testing) and are the first to design inorganic nitrate and nitrite capsules for cardiovascular disease.

Primary Outcome

"Post-doses" refers to that subjects will receive a single dose of each study drug, oral 15Nitrogen(15N)-labeled sodium nitrate and nitrite, in random order, separated by a 3-7 day washout period

Interventions

  • DRUG 15Nitrogen(15N)-labeled sodium nitrite
  • DRUG 15Nitrogen(15N)-labeled sodium nitrate
