Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Previous work demonstrates that the red blood cells of older adults do not release a potent vasodilator (ATP) as well as the red blood cells of younger adults. The investigators are targeting a pathway within the red blood cell using fasudil hydrochloride to determine if both the release of ATP from red blood cells and blood flow responses to low oxygen (hypoxia) and exercise in older adults can be improved.
